How to install a powered subwoofer

Learn how to install a powered sub and boost your bass

Powered subwoofers include all the elements of a subwoofer system — subwoofer, amplifier, and enclosure — in one convenient package. Here's a look at how you install a typical powered subwoofer.

Please note: As with any amplifier installation, you'll also need an amplifier wiring kit. The proper size of kit will be listed in the accessories for each powered subwoofer. If you need any help or just have questions about adding a powered sub, contact our advisors by phone, chat, or email. 

How to install a powered subwoofer | Video Transcript

No matter what kind of music you love, adding bass makes it sound better. Let's take a look at what it takes to install a powered subwoofer in your vehicle with the help of one of our guys from tech support.

Find a place to mount your sub

Before you get started, find a suitable place in your vehicle to mount your sub. The sub’s built-in amplifier generates heat, so adequate ventilation is important. And you'll want to place it somewhere that's not too difficult to access.

Wiring kit and speaker wire

Your powered sub does not come with the necessary wiring, so be sure to purchase an amp wiring kit that includes the wiring and fuses you'll need.

Disconnect the battery

First, disconnect the negative battery terminal to protect you and your gear during installation.

Step #1: Running power wire

Next, run the power cable from the battery to the powered sub. Some kits have the fuse assembly already put together. But if not, cut a short piece of the power cable, enough to cover the distance from the battery to the fuse holder location, and strip the insulation off both ends. Crimp the terminal ring from your wiring kit to one end, and attach the fuse holder to the other end. Strip the insulation from the end of the wire that leads to your amp and attach it to the other end of your fuse holder. It’s important to keep the fuse close to the battery since the lead between the terminal and the fuse is unprotected.

In most vehicles, you can pass the power cable through the firewall that separates the engine compartment from the main cabin using an existing entry point. Once you're inside the cabin, tuck the power cable under trim panels or your carpet along one side of your vehicle until you reach your powered sub location.

Step #2: Running turn-on wire and signal cables

After running the power wire, the next thing to do is run the turn-on wire and signal cables. Both the turn-on wire and RCA signal cables need to be connected to your stereo. Run these cables behind the dash to your stereo. The turn-on wire connects to a remote turn-on wire in your stereo's wiring harness. It's usually blue, but confirm this with your owner's manual. Plug the RCA cables into the appropriate RCA outputs on your stereo.

Run these wires, the turn-on wire, and the RCA cable, down the opposite side of the car from the power wire. This will prevent electrical noise from entering your system and spoiling your music.

All of this assumes you have an aftermarket stereo with preamp outputs. If you have a factory stereo then you'll get the signal to your powered sub a different way. You’ll want to make sure your amp has speaker-level inputs and "signal sensing" turn-on capability. In this case, you can just tap into the speaker wires behind your stereo, or possibly the rear deck speakers. Either way, this will get signal to the powered sub’s built-in amp.

Step #3: Connect the ground wire

The third primary connection is the ground wire. This wire should be connected to the vehicle's chassis. Look for a nearby bolt that you can fasten the ground cable to. The ground wire terminal should be in contact with the vehicle's bare metal. Sand away any paint at the contact point for the best connection.

Step #4: Make your wiring connections

Now, mount your powered sub and make your connections. Try to use gentle curves with your wires and cables when possible to prevent unnecessary wear and tear.

Before you fire it up to test, turn the built-in amp's gains all the way down. And reconnect your vehicle's negative battery terminal. Verify that the sub turns on when you start the car. Then you can play some music and set your gains.

If you have any questions about powered subs, please give Crutchfield a call.

    I just had a JL microsub+ installed into an 04 town car. Its connected to a recently purchased kenwood excelon DNX695S . to say that im not impressed with the bass is an understatement. At lower volumes bass is just ok when you turn radio up nass doesnt seem tp get louder. With that being said. With the 2 adjustments on the built in amp os there an adjustment i can make to make this sub hit harder. Ive read reviews where people say this 2 wooofer sounds betyer than 2. I find that hard to believe. I dont expect it to win any competitions but i would hope i can get my drivers seat to vibrate some. Any help would be greatly appreciated.

    I have an Alpine ILX-207 in a 2016 F150, with an iDatalink Maestro RR Module. Does the Blue/White wire on the back of this head unit have the ability to send the remote signal to a Kicker Hideaway? And how would i connect this? Just splice this right into the blue/white wire?

    Do I have to run a Rockville 10" amplified sub off the rear speakers or can I run it directly off the stereo unit, I just don't want to run it off the rear speaker wire. I have a sound stream xr1032b stereo

    Chris, You can probably wire the inputs either way, but using both left/right inputs for both subs may work better. Unfortunately for you, you'll have to use two controllers for your two subs.

    I have two Pioneer TS-WX130DA that I want to put into my 2018 Jeep Renegade Trailhawk (nav, no beats, 6-speaker stock). Should I run each sub as mono to the left and right channels? Or parallel them together as stereo to both the left and right (using speaker-level inputs, not RCA). Also, is there a way to use just one of the controller modules to adjust the gains on both?

    Hunter, Bazooka's BTA850FH 8" Bass Tube may be just the sub for you. It comes with a wiring kit for connecting to the system harness without needing a power wire run to the battery.

  • Hunter from Tucson, AZ

    I've scrolled through the above comments and didn't see this question, but I'm sorry if it's a duplicate ... Is it feasibly possible to connect a powered sub/amp to an alternate source of power besides the battery, perhaps a fuse box or similar? I'd like to avoid tapping the battery directly if possible.

    Anthony, Your factory radio won't power the sub, its onboard amplifier will do that. The FAST kit is made for exactly the application you want, connecting the sub's input to the factory speaker wiring.

  • Anthony Shaffer from West Chester

    I recently sold my 96 Blazer that I had originally purchased a Bazooka BTA850FH for. With the Blazer I had an aftermarket head unit with RCA outputs already so the hookup went smooth and easy. I now have a 2014 Ford Focus SE, and am curious the power output of the stock radio, and whether or not it'll be enough to power the sub. I've done countless hours of research online to find an answer with no luck. The sub has been sitting disconnect for months now. Before I buy the F.A.S.T kit again I would like to know if the stock radio can support it, not looking to upgrade the headunit or any other factor of the system since it performs very well. Any feedback is greatly appreciated.

    Joshua, The auto turn-on mode of that powered sub works when using the high-level inputs. For those, you don't need any "splitters." You tap the factory speaker wiring to get your sub's input signal.

  • Joshua Greener from Jupiter

    Posted on 4/5/2018

    I have that jbl powered sub. Does it need a turn on wire? I thought it had an automatic on/off function. Also on my 2010 Mazda 3, instead of getting new head unit I saw that you can use aux splitters and "RCA to aux" splitters to get the sub to match the music. Do you suggest this or should I just get an aftermarket head unit instead?

    Mike, When running multiple amps in a system, most people run one power cable from the battery to a distribution block. From there, a power cable runs to each amplifier.

  • Mike

    Posted on 3/30/2018

    Can I connect a powered sub (that's already installed) to an aftermarket amp (to power the door speakers)? I only want to run one power line to the battery, so could I connect the powered sub to the amp and move the power cable that's already in place to the amp?

    Paul, A great way to get a remote turn-on voltage for your amp is by using an Add A Fuse to add a fused circuit to your vehicle's fusebox. First find what style of fuse your vehicle uses - ATC, ATM, or ATMLPDT - and get the appropriate connector and a 2A to 10A fuse. Use the factory radio's fuse to add your circuit to.

    Ratnadeep, That sounds like a perfectly valid way to hook things up. In fact, my vehicle is set up the same way, with the radio's fade control functioning as a subwoofer level control. If there's something about your system that doesn't sound right, you should take it up with your installer.

    I have installed a powered 8" subwoofer tube to my car Hyundai Eon's factory fitted music along with 6.5" JBL components in the front door. I have factory fitted 5" speaker's on the rear. The technician who installed the woofer and front speakers did the following. He attached all the speaker's to one output from my stereo and another output to the woofer he said he did the same because my stereo does not have separate sub woofer out. Now when I turn the fadder controls on my stereo to one side my speaker's only work and when turned on the other side only woofer works. Pl. Advice whether this is correct and is some another way to get the maximum out of my music system.

    I bought the Sound Ordnance B-8PTD and wiring kit. I have a 2015 Jeep Wrangler 2 door. with the factory stereo. I also purchase your Crux rearview camera for the same vehicle. My question is about the Blue REM cable. Is this going to be necessary? I was thinking that I was just going to plug the RCA cables I got from you all to the RCA plugs that are extra in the white harness that I had to plug in for the Crux camera. And using the Remote knob I got with the powered amp should all be sufficient correct? if not can I please just be given a place to connect said blue REM wire. Thanks!!

    Melvin, Those powered subs each come with its own power cable and in-line fuse. You'll need to run both of them to the battery. An alternative method would be to run 8-gauge power wire with a 60-amp in-line fuse from the battery to a distribution block. From there you'd use the subs' power cable to get power to each sub. For input, use RCA Y-cords to supply the same signal to both subs.

    Chase, In car audio, one has to make compromises as to which position of a subwoofer sounds best in your vehicle and which position the subwoofer can actually fit into without interfering with the driver or passengers' legroom. Like Stephen says in the video, "Find a suitable place in your vehicle to mount your sub. The sub's built-in amplifier generates heat, so adequate ventilation is important. And you'll want to place it somewhere that's not too difficult to access."

    Gary, You can get the input signals for your powered subwoofer by tapping into the factory speaker wiring either behind the receiver at the wiring harness, or at a more convenient spot like your vehicle's rear speaker wiring. Great connectors to use would be Posi-Tap connectors, so you won't have to crimp or solder wires together.

    Joe, You can get a receiver with front, rear, and subwoofer RCA outputs, or get one with less and use RCA Y-cord adapters in order to get signal to your amps. I'll bet that 600W number attached to a 4-channel amp is a peak spec and worthless for planning an amp installation. But even at those numbers, I doubt you'll come upon any power supply issues with your amplifiers.

    Luis, You'll need a 10-gauge amp power wiring kit and some speaker wire. You connect the power wiring between the car battery and the powered sub. Ground wire goes from sub to chassis. And you'll use speaker wires to get the sub's input signals by tapping the car's rear seat side panel speaker wiring. Why don't you give us a call so an Advisor can help you get everything you need.

    Pete, A fuse is absolutely necessary in order to protect you and your vehicle from burning up in the event of a short circuit. It goes on the positive battery lead near the battery. Ground wires usually connect to the vehicle's chassis, not to the battery.

    Sekhar, yes, you'll still need to run a dedicated power cable to your vehicle's battery. Sub's are power-hungry by nature and you won't get the full performance of your powered sub without the proper wiring.

  • Robert Ferency-Viars from Crutchfield

    Posted on 5/26/2016

    Scott, it can be done. If you're currently using 10-gauge power and ground wires, it would be safest (and give better performance) to upgrade to 8-gauge, then use a distribution block to connect the power leads from each sub. Likewise for the ground. Or, you can run a second set of wires for the second powered sub. The audio input will be a little tricky, unless one of the powered subs happens to have an audio output. If you're using an RCA cable from the headunit, you'll have to use an RCA splitter to branch off to the new sub. Or you can just use the speaker-level inputs and tap into a speaker line.

    Les, there's definitely a fuse holder on that power line. It came pre-installed on the power cable. It's just a little further down the line and out of the camera shot. The kit I used was an older version of this 10-gauge kit from EFX.

    Virgil, a powered sub by design has its own amplifier built into the box. You don't need to connect it to your other amplifier. You simply need to run power from the battery. Enjoy!
