All about subwoofers

A comprehensive checklist and reference guide for putting a subwoofer in your vehicle

Subwoofer that doesn't fit

It's a good idea to plan out the system completely, before you buy the gear.

When planning a bass system, customers ask every day about where they should start. Doing it properly takes some planning and forethought, especially if you're starting small and intend to expand over time.

How big of a subwoofer system will you need?

When putting together a bass system, the first questions to ask are:

  • How much bass do I need?
  • How many subwoofers? 
  • How much power? 

The answers depend on the type of audio system you have currently, and what your end goals are. Estimate the power your subwoofer system may need in order for the bass to musically blend and balance well with your existing system. If you have:

  • A factory radio — you won't need more than 50 to 200 watts RMS of power for the bass.
  • An aftermarket receiver — you might want 200 to 300 watts RMS of power.
  • Amplified speakers with around 50 watts RMS per channel — 250 to 500 watts RMS is a good starting point.
  • A system with 100 watts RMS per channel — having at least 1,000 watts RMS, or more for the sub is not uncommon.

Choose a subwoofer and enclosure

The sound quality and volume of bass depends not only on the specific component sub you get, but also what style and size of enclosure it mounts in. For some background in what to look for in a subwoofer, see our Subwoofers FAQ. Then go to Subwoofer Enclosures article for help finding out which enclosure will work best for you. For further help in deciding which sub to get, you can look at our Subwoofer Shopping Guide or watch our How to Choose a Subwoofer video.

Choose an amplifier

Mono, 1-channel amplifiers are designed to work best with subwoofers and often feature filters and tone controls specifically made to handle bass. You will want an amp that can put out up to the subwoofer's top RMS wattage rating.

To learn more about amps, check out our Car Amplifiers FAQ. For help in picking which amp to get, see our Car Amplifier Shopping Guide or watch our How to Choose an Amplifier video.

Subwoofer wiring diagram

Plan out the wiring scheme to be sure the sub and amp can work together

Subs come in different impedances, and in dual and single voice coil models, in order to work in a variety of systems. An amp puts out more power to a low impedance sub than to a higher impedance sub. So, to find out how much power an amp can deliver, you have to know how the sub will be wired. To make some sense of all this, you can refer to a couple of articles: Dual Voice Coil Subwoofers and Wiring Subwoofers — What's all this about Ohms?

You might need to adjust your choice of sub or amp, so they'll work together properly. Changing your set-up on paper is a lot less challenging than exchanging purchased gear. Check out the different ways subs get wired in our Subwoofer Wiring Diagrams. These diagrams can help you decide which method will work best for the gear you've chosen.

A powered subwoofer is an easier solution

For many people, a small, self-contained, powered subwoofer will provide more than enough bass for their system. After positioning the powered sub, all you need to add are power cables and signal wires. You can learn more by watching the Crutchfield video on Installing a Powered Subwoofer.

Vehicle-specific enclosures with subs

Instead of the usual "sub-in-a-box," you might want to consider a vehicle-specific enclosure. Made to fit your car or truck, this enclosure contains a high-quality sub and fits into a convenient spot in your  vehicle. Some enclosures even include a built-in amp, for the ultimate in stealth bass. You don't lose much (if any) space, the sub is perfectly matched to its enclosure, and it has a factory look that won't alert potential thieves to your expensive sound system. To see if there's a vehicle-specific enclosure for your car or truck, visit our vehicle selector.

Amp power wire kits

It is absolutely essential for an amplifier to receive its full share of electricity through large power wires, in order to operate properly and safely. The wattage of the amplifier determines what the proper size power wires should be. Amplifier manufacturers usually recommend a particular power cable size for each of their amps. Or, you can use our Cable Gauge Chart to figure out the power cable size that's best for your system.

Amp wiring kits contain most of what you need to hook up your amp. Some kits even come with signal wires, the RCA patch cords that allow the signal to get from the receiver to the sub amp.

Fuses are for your safety

Always install the in-line power fuse near the battery. If something failed back by the amp, you don't want a live, high current wire stretched throughout your car and engine compartment, because it could possibly heat up and start a fire.

The signal wires

The music has to have a way to get from the receiver to your sub amp. If you have an aftermarket receiver, it probably has RCA outputs you can use. Plan on getting new, high-quality patch cables. If you have a receiver with no RCA outputs, you can tap into the existing factory speaker wires with new speaker wires, to use for a high-level input to your amp. The amp, of course, has to have a speaker-level input feature for this to work. To prevent noise, all signal wires should run through your vehicle as far away from any power cables as possible.

The speaker wires

If your sub system is going to put out more than 1,000 watts RMS, you can use 12-gauge speaker wire. But 16-gauge speaker wire works well for most installations. Take a hint and order twice as much as you think you need. You never know when a sub or amp's position will need adjusting and you'll be thankful you have the extra length.

And don't forget tools

There are some tools and connectors that will make your sub installation much easier. Take a look at what you might need in our video on Car Stereo Installation Tools.

Gather the gear

Before you start working, make sure you have everything you need. You'll want to gather your component sub(s), enclosure, speaker wire, amplifier, (or a powered sub), an amp wiring kit, signal cables, and any tools you think will come in handy.

Now is the time to install it

To see how an amp installation is done, see our Amplifier Installation Guide, and watch our video on Installing a Car Amplifier. You can also check out the Subwoofer Installation Guide for more tips and suggestions.

Make sure you always disconnect the car battery's negative, ground cable before working on the electrical system. Also, make sure the fuse is out of the in-line fuse holder until the installation is complete. Only then should you re-connect the battery ground and install the fuse.

Test — does it turn on and off correctly?

Make sure all volumes and gains are set to their minimum, and make sure all filters are off or disengaged. The sub amp should come on when you turn on the receiver. If the amp stays on even after you turn off the ignition, then you need to go back and re-wire the remote turn-on lead correctly to a switched power source. An amp that's always on will drain your car's battery in a hurry.

Gain up

Turn the gain up until it distorts, then back it off until the sound is clean again.

Tune your sub

Properly setting the gain and the filters of your sub amp is crucial to getting good bass without causing damage. See Tuning Your Subs for the "by ear" method of tuning your system. Another method involves using test tones and a multimeter to set the amp's gain to a target output voltage. Our Test Tones article helps explain that.

A lot of people notice changes in a new subwoofer's tone after a few months of play. Whether this "breaking in" period really effects the sub or not, a second tuning, a few months after the first, will make your ears happy.

Don't blow it

There are two ways to blow a sub. The first way is to over-power it: constantly playing music at a power level well beyond what the voice coil can stand. Eventually, it burns up.

The other method of blowing a sub doesn't involve power, but distortion, often called "clipping." That crumbling, crackling, gritty, or hissing sound can destroy a subwoofer no matter what the volume. There're a couple reasons why. One is that during the flat parts of a clipped signal, although plenty of current flows through the voice coil, there's no movement, and hence no cooling. When that happens, the coil overheats.

Another reason is that severely clipped waveforms force the sub's coil and cone to try to move at infinite speed when changing direction. That can't happen, and either the cone or the coil dies. Under-powering is often the contributing factor in a blown sub because a distorted signal gets applied in an attempt to get more volume.

Don't stress your vehicle's electrical system

Capacitors should only be used if your lights dim a little on hard bass hits. For more information, see Capacitors FAQ. If your lights dim a lot whenever the music plays, then your sound system is overwhelming your vehicle's electrical system, and could damage the battery and alternator. Refer to the article entitled Car Lights Dim When the Music Plays for some suggestions on how to solve that problem.

Rock on, but be cool

If your car stereo can be heard a block away, that's impressive -- but it might not make the best first impression. Enjoy your music, and share it with those who'll appreciate it, but don't infringe on someone else's right to peace and quiet.

Speaking of sharing, send us some photos of your finished installation. Our Custom Car Showroom is a great place to show off your system, or find inspiration for your next car audio project.

    Hi, Was Wondering what size cable to run to my x2-400w (rms), 4 ohm dvc sub woofers, are there any formulae you use to determine this? I understand that 16 gauge would work, but would I gain any real audible performance by using 12 Gauge etc.? Cheers

    Buck Pomerantz from Crutchfield

    on 10/27/2020

    Jaeden, For wiring subwoofers, we recommend using wires of 12- to 16-gauge in size. There will be no audible difference between them - just less power loss with larger wire.

    on 10/16/2020

    Craig, If you're talking about speaker wire between the amp's output terminals and the sub's wiring terminals, then 6-gauge is already wildly over-doing it and you won't need any upgrading. If you're talking about power and ground wiring, then you might need to upgrade to 4-ga.

    So we just put 2 pioneer 10 inch subs in my girlfriends Honda Accord with a Evo2 amp... her car is a 2017 and we are running the subs with a stock head unit and just running a reviver instead of off the radio, but when all doors are closed the subs starts hitting super hard, constant wounds no fluctuation in power, but as soon as you open a door or break the current of the vehicle the subs stop.. what could this be?

    William, Your Honda has an active noise cancellation (ANC) system which reacts poorly with subwoofers. You might look into disabling it. Do an online search for disabling the ANC in a Honda Accord and I'm sure you can find someone online to show you how to do that.

    So I bought an amplifier and accidentally bought a powered sub instead of a normal one. My question is. Instead of running 2 power wires from the battery. Can I run one 8 awg to the amplifier and then run my subs power and ground wire to the amp power and ground terminals?

    Commenter image

    Buck Pomerantz from Crutchfield

    on 8/26/2019

    Dallas, You should not daisy-chain power wires from one amp to the other. When running two or more amplifiers in a system, you run one fused power wire from the battery to a distribution block. Then you run power wires from the distribution block to each amp.

    I have two massive audio mma104 that can handle 500 watts rms. Do I need a one channel 1000 watt amp? Does it equally distribute 500 watts to each speaker or do I get a 500 watt amp?

    Commenter image

    Buck Pomerantz from Crutchfield

    on 5/15/2019

    Kyle, Two DVC 4-ohm subs rated for 500 watts RMS each will work best with an amplifier that can put out between 750 and 1500 watts RMS into one ohm or 4 ohms, like a Pioneer GM-DX971. Wired like this, each sub will receive one-half of the amp's total power output.

    I'm planning on buying a powered subwoofer off of here, because my speakers already run through a good enough amp. I'd like to know if having different wattage coming from my current amp (200w across 4 channels) and a new powered sub amp will affect my sounds quality. Will different wattages within separate amps cause an unbalanced sound between the sub and the speakers? Should I just try to get as close a possible or does it even matter at all when I adjust sound from the receiver? I know nothing please help.

    Allen, The amount of power going to your subwoofer should be greater than what each speaker gets. You balance the bass with the rest of the sound with your system's sub level control, on the receiver, or with the subwoofer amp's gain control.

    Eric, We recommend using 18-, 16-, or 14-gauge speaker wires for speakers and 16-, 14-, or 12-gauge speaker wires for subwoofers. Stranded speaker wire is preferred because its flexibility protects it from breaking under the conditions of constant vibration.

    Devonte, It ultimately depends on how your subs are wired, but it sounds like one sub is 180 degrees out of phase from the other. Reversing the polarity of one of your subs, switching the positive and negative leads, should solve the issue.

For the subwoofer, it says it will work with anywhere from 200-500 watts RMS. Will this sub be a good match for this amp? I want a really good sub with for spl purposes, and i want a sub that has high excursion capabilities, and this sub seems like a good match for what I want and for what the amp can give to it, but I still would like a professional opinion. I do not want to spend anymore then $200 on a 12 inch sub. Please let me know if this earthquake sub is a good match for my amp, or if you recommend something else, please give me some other ideas.

    Shannon, If your sub is the DVC 2-ohm model, you can hook it up to that amp and produce 200 watts RMS of bass. If it's the DVC 4-ohm model, it'll put out 400 watts RMS. The 500 watts RMS rated sub will take either wattage, whether that's loud enough is up to you.

    Noel, Rockford Fosgate makes two versions of that sub, a DVC 4-ohm and DVC 2-ohm model, both rated for 400 watts RMS. If you have two DVC 4-ohm subs, you'd look for an amplifier that can put out between 600 and 1200 watts RMS at 1-ohm, like a Pioneer GM-D8601. If you have two DVC 2-ohm subs, you'd look for an amplifier that can put out between 600 and 1200 watts RMS at 2-ohms, like a Pioneer GM-D9601. That Rockford Fosgate amp is not a good match for those subs.

    Scott, Does the subwoofer have a single voice coil (SVC) or dual voice coils (DVC)? It makes a difference in how they can get wired to an amplifier. If you want a question answered about a system, you must identify the equipment by brand names and model numbers. And, most people will think that 350 watts will sound better than 250 watts because it'll be louder.

Or would I be better off getting the 4 ohm/300 watt version of that subwoofer because at 4 ohms the amp puts out 250 watts RMS. And would one power set up sound better than the other?

    Matt, That's a great question. The answer involves the effects of wire size on a circuit's voltage, current, and resistance described in the mathematics of Ohm's and Joule's Laws. Let's take as an example a 500 watts RMS Class D amplifier powering a 4-ohm subwoofer in a 12-volt DC system. (I'll do the math behind the scenes.) On the output side, a 500-watt output through a 4-ohm sub requires 44.7 AC volts pushing 11 amperes of current. For the input, an 80% efficient 500-watt amplifier will require 625 watts of 12-volt DC and draw 52 amperes of current. Thin wires have higher resistance and can carry less current than thick wires. If we tried passing 52 amperes through a thin 14-gauge wire, for instance, the wire would heat up, due to its resistance to the current flow, lose voltage for the same reason, and might even burn through. The same wire would have no problem, however, passing 11 amperes without any heating or voltage loss.

    Dane, It depends on the vehicle, the factory amplifier, and the powered subwoofer you want to install. Many vehicles use digital signaling between the receiver and amp, so you can't use the amp's input signal for your sub's input. Most powered subwoofers feature high- or speaker-level inputs, so they can get their input signal from a vehicle's amplifier outputs or speaker wiring.

I've underpowered, overpowered and never blown a sub before. I currently am running 2 rockford punch 10"s on a 12.5watt rms amp in my truck. Yes I did just say 12 and a half watts. I've found that as long as you use a premium crossover (not one from an amp, like a physical crossover that hooks up between the amp and sub), you can underpower, and slightly overpower it over the peak power. I prefer Klipsch crossovers from their Synergy series of speakers. If you break a sub in before you pound it. It'll last longer, and it'll sound better too. Also if youre going to buy a premium brand sub, Rockford and JL are the best, Kicker and Kenwood is second, Pioneer and JBL are third. If you have the cash buy the Sundown Audio SA-8 subwoofer. You'll never regret it until you'redealing with broken windows on every car around you.

    Mounir, It shouldn't matter what anyone thinks of your subwoofers as long as they sound good to you. A sound system will only drain your car's battery if you play music with the engine off. While the engine's running, all electrical needs are taken care of by the alternator.

    I got some dual subwoofers on my Pontiac g6 they sound great but I heard they aren't any good? Also does it drain a lot from the car battery?
