Choosing the best speaker wire for car audio is less about chasing the biggest number and more about matching gauge, length, conductor material, and jacket flexibility to the installation. A wire that is easy to route and identify can save more time than a technically heavier cable that is difficult to fit behind panels.
My first choice is GEARit 16 Gauge Speaker Wire 100FT 16/2 Speaker Cable. Its flexible PVC jacket should be manageable in tight vehicle interiors, while the CCA construction keeps the cable lighter and more budget-friendly.
My second choice is GEARit 14 Gauge Speaker Wire 500FT 14/2 Speaker Cable. The trade-off is that its bulk and quantity may be unnecessary for a single small installation, even though the soft jacket and printed measurements make it convenient to use.
My third choice is Install Link 14 AWG Gauge Speaker Wire Car or Home Theater. Install Link 14 AWG Gauge Speaker Wire 100 Feet Car earns my third-choice position by offering a useful middle ground: 14-gauge CCA conductors, a soft-flex jacket, and a manageable 100-foot length. It is especially appealing when you want enough wire for a complete vehicle project without storing a large spool afterward.
The comparison below explains where all seven options fit, followed by individual buying guidance, setup advice, gauge and conductor information, common mistakes, and focused answers to practical installation questions. The goal is to help you choose a wire that suits your route and equipment rather than simply selecting the thickest cable available.
7 Best Speaker Wire for Car Audio Comparison
I selected these options based on their direct relevance to vehicle speaker installations, useful details such as gauge, length, flexibility, polarity identification, and conductor material, plus available customer-feedback evidence. The list also includes both CCA and oxygen-free copper choices, several lengths, and multiple gauges so the comparison reflects different budgets and installation sizes rather than one narrow use case.

GEARit 16 Gauge Speaker Wire 100FT 16/2 Speaker Cable
This GEARit cable is a sensible all-around option for a typical car speaker upgrade. The 16/2 layout gives you two conductors in one jacket, so each speaker run stays organized instead of requiring separate loose wires. Its 100-foot length is generous for most single-vehicle projects, with enough room to measure carefully and avoid coming up short after routing around seats, trim, or door openings.
The soft PVC jacket is another practical advantage. It should bend around tight interior spaces more easily than a stiff cable, which matters when working behind dashboards or along concealed paths. Sequential foot markers let you estimate cuts before stripping the ends, and the polarity markings help keep positive and negative connections consistent from the amplifier or receiver to each speaker.
The important limitation is the conductor material. This is CCA, or copper-clad aluminum, rather than pure copper. That makes it lighter and generally more economical, but buyers should not treat the stated 16-gauge size as identical to every pure-copper cable carrying the same label. For ordinary speaker-level routing and a cost-conscious build, it remains a practical fit; demanding, unusually long, or high-output runs deserve closer attention to resistance and gauge.
Pros
- Useful 100-foot length for many single-car installations
- Flexible jacket, polarity markings, and sequential foot markers
- 16/2 two-conductor format is simple to route and connect
Cons
- CCA construction is not the same as pure copper
- May be more cable than needed for a very small repair
My Opinion
This is my strongest general recommendation because it balances manageable handling, useful length, and accessible pricing logic without becoming excessive for a normal vehicle project. It suits beginners who want clear markings and enough material to measure twice, while buyers seeking maximum conductor purity should look at the Skar Audio option later in the list.
GEARit 14 Gauge Speaker Wire 500FT 14/2 Speaker Cable
GEARit’s 14-gauge spool is aimed at buyers who need substantial quantity rather than a short replacement section. Five hundred feet can support a complete multi-speaker installation, several vehicles, a home-and-car audio mix, or future projects. The 14/2 construction also keeps each run paired, which reduces the chance of losing track of conductor orientation while routing through a vehicle.
Compared with 16 gauge, 14 gauge provides a larger conductor size for buyers who prefer extra margin on longer speaker runs or more demanding systems. That does not make it automatically superior in every car. A large spool can be awkward to store, and its length is wasteful if you only need a few feet for one door speaker or a small repair.
The soft PVC jacket should help it pass around furniture, equipment areas, and tight automotive spaces without excessive kinking. Foot markers make a 500-foot roll easier to manage because you can plan cuts and keep track of what remains. Clear polarity markings are equally useful when several pairs are being run at once. The CCA construction lowers weight and cost, but it also means buyers should compare the actual application rather than assume the 14-gauge label tells the entire story.
GEARit states that the wire strips easily and works with banana plugs, spade tips, or direct terminals. A two-year support commitment is also supplied with the product information, which may matter to DIY buyers who want help if a spool or connection project raises questions.
Pros
- 500-foot quantity fits large or repeated installation work
- 14/2 format, polarity markings, and foot markers aid organization
- Soft jacket is easier to route than a rigid cable
Cons
- Much more cable than one small vehicle normally requires
- CCA may not suit buyers specifically seeking pure copper
My Opinion
This is the best quantity-focused choice in the group. I would choose it for a full custom build, several vehicles, or a workshop drawer, but not for a single modest speaker replacement where a 100-foot roll is easier to handle and store.
Install Link 14 AWG Gauge Speaker Wire Car or Home Theater
The red-and-black Install Link version makes polarity identification especially intuitive. Its contrasting jacket colors provide an immediate visual cue while connecting an amplifier or receiver to a speaker, and the 100-foot length is substantial without approaching the storage commitment of a 500-foot spool. For a first installation, that balance can make planning less intimidating.
Its 14-gauge, two-conductor construction is suitable for common speaker-level routes in cars, home theater systems, and studio applications according to the supplied product information. The soft-flex jacket should help it move around trim and other tight spaces, while the stranded construction supports bending during routing. It is also described as easy to strip, a useful benefit when preparing several ends.
There is a clear trade-off in the CCA design. Copper-coated aluminum is a cost-conscious material and can keep the cable flexible and light, but it is not the same material choice as the 99.9% oxygen-free copper option ranked seventh. Buyers who are prioritizing economy, manageable installation, and an adequate 100-foot supply may find that acceptable. Those who place conductor purity and corrosion-focused construction first should compare the alternatives before ordering.
The product information gives this version a 4.8 customer rating from 3,549 ratings, which provides meaningful marketplace feedback, although it cannot replace matching the cable to your own route and equipment.
Pros
- Red-and-black colors make polarity easy to follow
- 14-gauge, 100-foot format suits many complete projects
- Flexible jacket and stranded conductors support easier routing
Cons
- CCA construction is a compromise compared with pure copper
- Color contrast may matter less if the cable will be fully hidden
My Opinion
This is a strong straightforward choice for a beginner who values visual organization. It offers the useful middle gauge and length many car projects need, and the red/black jacket is a small but genuine convenience when multiple connections must stay consistent.
Install Link 14 AWG Gauge Speaker Wire Car or Home Theater
Functionally, this blue-and-black Install Link cable sits close to the red-and-black version above. It uses the same 14-gauge CCA construction, 100-foot length, two-conductor layout, and soft-flex jacket. The meaningful difference for a buyer is the color scheme, which can be useful when separating left and right channels, identifying rear-speaker routes, or coordinating cable colors with an existing installation plan.
Blue and black still provide a visible distinction between the conductors, so the cable can help reduce polarity mistakes during a rushed connection. That is particularly helpful when several runs enter the same amplifier area. The flexible jacket also supports routes through tight vehicle interiors, while the stranded conductors are intended to strip and connect without making basic preparation unnecessarily difficult.
As with the other Install Link CCA options, the material is the main limitation to keep in mind. The cable is positioned as a cost-effective solution for car audio, home theater, and studio work, not as a pure-copper specialty cable. A 100-foot roll is a practical amount for many vehicles, but measure the actual path before cutting because door and hatch routes can consume more material than a simple straight-line estimate suggests.
This version makes the most sense when color coding has value in your system. If you already use blue identification for a particular channel or want a different appearance from the red/black alternative, the choice is simple; otherwise, the two Install Link 14-gauge versions are broadly similar on paper.
Pros
- Blue-and-black jacket supports visual channel organization
- 100-foot length is practical for many vehicle projects
- Flexible CCA cable is light and manageable to route
Cons
- Does not provide the pure-copper construction some buyers want
- Color choice offers limited value if all runs are hidden
My Opinion
I would select this version when blue-and-black identification fits the rest of the wiring plan. It is a dependable value-oriented format, but its rank reflects the fact that the color is mainly an organizational preference rather than a performance upgrade over the other 14-gauge Install Link option.
Install Link 16 AWG Gauge Speaker Wire Car or Home Theater
This Install Link cable keeps the same convenient 100-foot format while moving to 16 gauge. That smaller size can be easier to tuck behind trim, route through compact openings, and work with when a vehicle has limited space around the speaker terminals. For standard door-speaker replacements or moderate runs, the reduced bulk may be more useful than choosing a heavier cable simply because it looks substantial.
The frosted red-and-black jacket remains beginner-friendly. It gives the two conductors an obvious visual distinction, and the soft-flex covering should bend through interior pathways without fighting every corner. Install Link also describes the stranded wire as easy to strip, which helps when preparing several speaker ends for direct terminals or compatible connectors.
CCA construction keeps the cable lighter and more budget-conscious, but it is the same reason to avoid treating this wire as a universal answer for every amplifier setup. Gauge, run length, and system demand should be considered together. A shorter route to an ordinary car speaker may be a sensible fit, whereas an unusually long run or a high-output application may justify examining a thicker option.
The product is also described for home theater and professional studio use, so it is not limited to vehicles. That flexibility can be useful if leftover cable will be repurposed later. Still, buyers should not pay for extra length they do not need; a measured cut plan helps avoid both waste and an unexpectedly short final run.
Pros
- Compact 16-gauge size is easy to route in crowded interiors
- Red-and-black colors make conductor identification simple
- 100-foot roll covers many ordinary speaker installations
Cons
- Less conductor size than the 14- and 10-gauge alternatives
- CCA is not the choice for buyers seeking pure copper
My Opinion
This is a good fit for ordinary, space-conscious installations where flexibility and easy routing matter. I would keep it on the shortlist for factory-speaker replacements and moderate runs, while moving up in gauge when the route or system demands more conductor capacity.
Install Link 10 AWG Gauge Speaker Wire Car or Home Theater
The 10-gauge Install Link option is the thickest cable in this comparison but it is supplied in a shorter 50-foot length That combination makes it more specialized than the 100-foot 14 and 16-gauge choices A buyer working on a compact system with a demanding speaker run may appreciate the larger conductor size while someone routing wire through narrow doors and trim may find the extra thickness more difficult to.
The blue-and-black two-conductor jacket gives the wire clear polarity identification, and the soft-flex covering is intended to keep a heavy cable workable during installation. It is also described as suitable for car audio, home theater, and studio connections. The 50-foot quantity can reduce leftover material when the project is carefully measured, but it leaves less room for errors or complicated routes than a longer spool.
CCA is an important qualification here. The 10-gauge label indicates a larger size than the other Install Link options, yet the aluminum core with copper coating remains a different material approach from pure copper. Buyers should choose this cable because the route and system justify the larger gauge, not merely because the number is bigger. Thick wire can take more effort to strip, terminate, conceal, and secure.
Before purchasing, measure both speaker runs and the path to the amplifier, including bends and service loops. If the final route needs more than 50 feet, this roll will not provide a comfortable margin. Conversely, when a measured project fits, the shorter package may be a sensible way to avoid storing a large surplus.
Pros
- Largest gauge in the comparison for buyers needing a heavier cable
- Blue-and-black jacket provides clear conductor identification
- 50-foot length can suit a carefully measured installation
Cons
- Thicker cable may be harder to hide and terminate
- 50 feet leaves limited allowance for measuring mistakes
- CCA is not equivalent to pure copper
My Opinion
This is a targeted choice rather than the default winner. It is worth considering when a larger gauge and a 50-foot quantity align with the project, but most beginners will find a 14- or 16-gauge 100-foot roll easier to plan and install.
Skar Audio 14 Gauge Elite Oxygen-Free Copper Audio Speaker Wire
Skar Audio takes a different approach from most options here by using 99.9% pure oxygen-free copper. That gives this cable a clear appeal to buyers who specifically want a pure-copper conductor instead of CCA. The 14-gauge size remains practical for many speaker connections, while the blue-and-white jacket makes the two conductors easy to distinguish during installation.
The 30-foot length is the main constraint. It may be ideal for a short replacement, a single pair of speakers, or a carefully measured amplifier-to-speaker route, but it is less forgiving for a full vehicle rewiring project. Buyers should map the path before ordering and allow enough material for bends, terminal preparation, and a little service slack. Running short is more frustrating than having a modest amount left over.
Skar Audio also specifies a tinned outer coating for corrosion resistance and a soft-touch matte jacket for flexibility. Those details may appeal to vehicle owners concerned about long-term exposure around automotive wiring areas, although proper routing and protected connections still matter. The true-to-spec 14-gauge claim makes the cable attractive to shoppers who want the stated gauge and conductor material to be central parts of the purchase.
Customer feedback shows a 4.7 rating from 607 ratings. That is useful context, but the shorter length and typically more material-focused positioning mean it is not automatically better for every installation. Its strongest advantage is the pure-copper construction, not quantity.
Pros
- 99.9% pure oxygen-free copper conductor
- Tinned outer coating is specified for corrosion resistance
- Flexible blue-and-white jacket with clear color coding
Cons
- 30-foot length may not cover a complete vehicle project
- Pure-copper construction may cost more than CCA alternatives
My Opinion
This is my preferred alternative for buyers who place conductor material ahead of quantity and want a compact, pure-copper 14-gauge option. It is especially attractive for a measured short run, but the 30-foot package requires more careful planning than the larger rolls.
How I Selected These Speaker Wire Options for Car Audio
I started with products explicitly positioned for car audio speaker connections, then compared the details that affect real installation decisions: conductor gauge, total length, two-conductor layout, jacket flexibility, polarity identification, and the difference between CCA and oxygen-free copper. I also considered whether the package made sense for one vehicle, several projects, a short repair, or a more demanding route.
Customer feedback helped provide additional context rather than acting as the sole ranking factor. GEARit’s 16-gauge cable has a 4.7 rating from 9,404 ratings, while the 14-gauge spool lists a 4.8 rating from 560 ratings. The Install Link 14-gauge options share a 4.8 rating from 3,549 ratings, its 16-gauge option lists 4.8 from 3,086 ratings, and the 10-gauge version lists 4.8 from 681 ratings. Skar Audio lists 4.7 from 607 ratings.
Gauge and length only help when they match the route. A shorter pure-copper cable can be the better purchase for one measured repair, while a longer CCA spool may be more practical for a complete multi-speaker installation.
The ranking also reflects product identity and use-case diversity. The first positions favor balanced, broadly useful formats; the middle choices show how color and gauge change the installation experience; and the final option highlights a pure-copper alternative. None of these rankings claim hands-on performance testing, laboratory resistance measurements, or a universal match for every amplifier and speaker combination.
Do not select a cable solely because it carries the largest gauge number. The correct choice also depends on how much wire is required, how tightly it must be routed, what terminations it accepts, and whether CCA meets your material preference.
How to Choose Speaker Wire for Car Audio
The best speaker wire for car audio depends on the actual route, speaker connection, and amount of cable required. Start by measuring the path from the amplifier or receiver to each speaker, then compare that measurement with the available length and choose a gauge that suits the run without creating unnecessary installation difficulty.
- Choose the gauge after considering run length, system demand, and available space.
- Confirm whether you prefer CCA or pure copper before comparing price and quantity.
- Measure around panels, seats, and bends instead of estimating a straight-line distance.
- Look for clear polarity markings if several speaker runs will share one amplifier area.
- Buy enough cable for service slack, but avoid an oversized spool when the project is small.
Gauge: 10, 14, or 16?
Gauge numbers work in reverse: a smaller number represents a larger conductor. The 10-gauge Install Link cable is physically heavier and may suit a buyer who specifically wants a larger cable for a measured run, but its thickness can make routing and termination harder. Fourteen gauge is a versatile middle ground represented by several products here. Sixteen gauge is slimmer and often easier to conceal, making it practical for many ordinary speaker routes where space is limited.
There is no benefit in forcing a thick cable through a cramped pathway if the installation becomes unsafe, poorly secured, or difficult to terminate. Conversely, a very long route should not be planned around the thinnest cable solely because it is easy to hide. When the equipment requirements are unclear, consult the amplifier and speaker documentation before deciding.
CCA versus oxygen-free copper
CCA uses an aluminum core with a copper coating. It is lighter and commonly positioned as a more economical option, which explains why it appears throughout the GEARit and Install Link choices. Oxygen-free copper uses a different conductor material; the Skar Audio cable specifies 99.9% pure oxygen-free copper. Buyers who prioritize pure copper may prefer that option, while buyers focused on quantity, weight, and budget may accept CCA for an appropriate route.
Do not compare only the gauge printed on two cables while ignoring conductor material. Two products with the same nominal gauge can still represent different material choices and different ownership priorities. Read the product details, match the cable to the planned run, and avoid assuming that a marketing term means every cable has the same construction.
Length and quantity
A 30-foot package can be convenient for one short run but restrictive for a full vehicle. A 50-foot roll offers more room, while 100 feet is a comfortable amount for many single-car projects. The 500-foot GEARit spool is better suited to repeated work or multiple systems. Before ordering, measure both conductors as a paired route and add enough allowance for bends, stripping, and a small service loop near each connection.
Jacket color and polarity
Polarity markings prevent avoidable wiring errors. Red/black and blue/black jackets make the two sides easy to identify, while printed markings on the cable can remain useful when the jacket colors are less obvious. Choose one consistent convention and follow it from the amplifier to every speaker. A color difference is not a performance upgrade, but it can make a complicated installation easier to inspect later.
How to Measure a Speaker-Wire Run
Good measurements start with the actual route, not the distance between two points on a diagram. Use a temporary length of string or inexpensive spare wire and follow the planned path from the amplifier to the speaker. Include the route around trim, under carpet, through a door area where appropriate, and into the final terminal location.
Build in a sensible allowance
Once the temporary route reaches both connection points, measure it and add a modest allowance for stripping, bends, and repositioning. Avoid adding so much extra that the cable becomes a tangled bundle behind a panel. If you are cutting multiple runs from one spool, write down each length first and check the total against the cable you plan to buy.
Plan the cuts before stripping
Sequential foot markers are helpful because they make it easier to confirm how much cable remains and where a cut should occur. Mark both ends of every run with its destination before pulling the cable into place. Labeling “left front,” “right rear,” or another clear destination can prevent confusion when several identical-looking pairs meet near the amplifier.
How to Route Speaker Wire in a Vehicle
Route speaker cable away from moving pedals, hinges, sharp metal edges, seat tracks, and locations where occupants may step on it. The wire should not be left loose where it can rub against trim or become caught during normal vehicle use. A flexible jacket helps with routing, but it does not replace careful placement and secure retention.
Keep the path protected
Use existing protected pathways where practical, and avoid forcing a cable through an opening that can pinch the jacket. At door areas, allow enough movement for the door to operate without stretching the wire. If a route passes near an edge, reposition it or add suitable protection rather than relying on the jacket to absorb constant abrasion.
Separate and label the runs
Keep each speaker pair organized as it travels toward the amplifier. Labeling both ends is worthwhile even if the color coding seems obvious during installation. If the system is changed later, labels can save time and reduce the chance of reversing one speaker or connecting the wrong channel.
How to Strip and Connect Speaker Wire
Cut the cable cleanly, then remove only enough jacket and conductor insulation to fit the selected terminal. Excessively long exposed strands can touch an adjacent terminal or make the connection harder to secure. Twist stranded conductors neatly without crushing them, and check that no loose strand is left outside the terminal.
Choose the terminal style first
The supplied product details indicate compatibility with direct terminals, banana plugs, and spade tips where applicable. Confirm the terminal size and connection method before cutting every run. If a connector requires a particular amount of stripped conductor, prepare a short sample first so the remaining cable is not repeatedly cut down.
Check polarity before powering up
Use the marked or color-coded conductor consistently. Connect the same side of the pair to the positive terminal at both ends, then do the same for the negative side. A reversed speaker may still produce sound, but inconsistent polarity can affect how speakers work together, so a final visual check is worthwhile before the system is powered.
How to Make Speaker Wire Last Longer
Most ownership problems begin with poor routing, loose terminals, or repeated movement rather than with the visible jacket itself. Leave a small, controlled service loop where a component may need to be removed, but do not coil excess cable tightly into a hot or crowded area. Keep connections clean, secure, and protected from unnecessary moisture.
When servicing the audio system, inspect sections that pass near doors, seats, hinges, or trim edges. Look for crushed insulation, exposed strands, pulled terminals, or a cable that has shifted into a moving path. Replace damaged sections instead of hiding them under a panel and hoping the symptom disappears.
Troubleshooting Speaker-Wire Problems
If one speaker is silent, begin with the simple checks: confirm both conductors are firmly secured, verify the correct amplifier channel, and inspect the cable for a break or exposed strand. If the problem moves when you swap the suspected cable with a known-good run, the cable or its termination becomes a stronger suspect.
Intermittent sound
Intermittent audio often points to a loose terminal, a partially broken conductor near a connection, or cable movement around a door or panel. Turn the system off before handling connections, then inspect and remake the affected end if necessary. Avoid pulling on the cable itself when removing a trim panel.
Weak or unusual output
Confirm that the positive and negative conductors are connected consistently and that no strands are touching another terminal. Also check the amplifier and speaker documentation for connection requirements. Do not assume a thicker cable will solve every sound problem; an incorrect channel, damaged speaker, or poor terminal can create similar symptoms.
Common Mistakes When Buying and Installing Speaker Wire
Small planning errors can waste more time than the actual connection work. The most common problems are buying the wrong amount, confusing gauge with material, cutting before measuring, and routing the cable where it can be pinched or rubbed.
- Buying by gauge alone: Compare length, conductor material, jacket flexibility, and the planned route too.
- Ignoring the 30- or 50-foot limit: Measure the complete path before choosing a shorter package.
- Assuming CCA is pure copper: Read the conductor description and decide whether that trade-off fits your priorities.
- Cutting without labels: Mark both ends before pulling several similar runs into place.
- Leaving extra conductor exposed: Strip only what the terminal needs and check for stray strands.
- Routing beside moving parts: Keep the cable away from pedals, hinges, seat tracks, and sharp edges.
Measure first, label every run, and inspect the final route with the vehicle’s moving parts in their normal range. A neatly connected cable is still a poor installation if it can be pinched or abraded.
When to Replace Car Speaker Wire
Speaker wire does not have a fixed replacement schedule. Replace it when the jacket is cut, crushed, brittle, pulled from a terminal, or repeatedly exposed to rubbing. A wire that has been disturbed during a panel repair deserves an inspection before it is hidden again.
If the system is being upgraded, replacement may also make sense when the existing cable is too short, difficult to identify, or unsuitable for the new route. Reusing intact wire can be reasonable when its material, gauge, length, and condition match the new equipment. Do not replace a sound cable solely to obtain a different jacket color unless organization or routing genuinely improves.
FAQS About Best Speaker Wire for Car Audio
What gauge speaker wire should I use in a car?
Fourteen gauge is a versatile middle choice for many vehicle speaker installations, while 16 gauge can be easier to route through tight spaces. Ten gauge is substantially thicker and should be selected for a specific measured need rather than automatically treated as better. Always consider run length, equipment requirements, and available routing space together.
Is CCA speaker wire suitable for car audio?
CCA can be suitable for a cost-conscious car audio installation when its gauge, length, and route fit the system. It uses an aluminum core with a copper coating, so it is not the same material as pure copper. Buyers who specifically want 99.9% oxygen-free copper should choose a product that clearly states that construction, such as the Skar Audio option listed here.
How much speaker wire do I need for a car?
Measure the real path from the amplifier or receiver to every speaker, including bends and the amount needed at both terminals. Add a modest allowance for stripping and service slack. A 30-foot package may suit a short run, 50 or 100 feet can cover many single-vehicle projects, and a 500-foot spool is more appropriate for multiple installations or future work.
Does speaker-wire color affect sound quality?
No. Blue, red, black, and white jackets do not independently improve sound quality. Their value is organizational: contrasting colors and polarity markings make it easier to connect each conductor consistently. Choose the color scheme that helps you label and inspect the installation accurately.
Can I use home speaker wire in a car?
Wire sold for both home and car audio can be suitable when its gauge, length, flexibility, and conductor material match the vehicle route. The important considerations are installation space, protection from rubbing or pinching, secure terminals, and correct polarity. A product’s stated application should be checked rather than assumed from its appearance.
Final Thoughts
The best speaker wire for car audio is the cable that fits the route, connection, and material preference without creating unnecessary installation problems. My top three are the GEARit 16 Gauge Speaker Wire 100FT 16/2 Speaker Cable for balanced everyday use, the GEARit 14 Gauge Speaker Wire 500FT 14/2 Speaker Cable for large or repeated projects, and the Install Link 14 AWG Gauge Speaker Wire Car or Home Theater for a practical 100-foot middle ground.
