View Full Version : Subwoofer Power Wire Through Firewall Write-up

05-07-2012, 01:08 PM
Hi everybody,

So after a failed search for a step-by-step write-up on how you could run the power cable for an aftermarket subwoofer, I decided to make my own. This is a basic write-up for running the power cable to an aftermarket subwoofer amp in the trunk.

1.)Remove the black plastic shroud that covers the air filter to expose the rubber grommet where the power cable will be running though.

2.) Poke a hole through the grommet to run your power cable through.

3.) I made the mistake of not poking a hole and realized this after everything was hooked up. So I just cut out a small section of the rubber to make it fit

4.) Now to retrieve the power cable on the inside of the car, you'll have to flip down your glove box. To do this, there are these rollers on each side of the glove box that keep the glove box from flipping all the way down. There is a spring that allows the rollers to move so you can "unhook" it from the notches on the glove box.

5.) After you unhooked the rollers, the glove should flip down all the way to give you access to the power cable you just ran.

6.) After snaking the coat hanger through the grommet it should end up somewhere in the middle or at least visible so you can grab it and pull it through

7.) Remove these screws from both side of the center console.

8.) At the very back of the center console, take off the cover for the ash tray and you'll see these two bolts. Take them off and your center consol will slide right now. If you have a phone jack, remember to not yank it out when you take the center console off. The plastic handbrake pieces all slide out.

After step 8, it should be pretty self explanatory. The rear seat just pops off - it doesn't have any bolts or screws holding it into the place. The carpeting might be hard to feed the wires through so what I did was I shoved a wrench in there and pried it up so I can grab the wires. My ground wire to the amp was bolted to on of the seat belt bolts.

If you have any other questions, feel free to shoot me a PM. Hope this is helpful to you guys.
