anybody have subwoofers in their trunk that did it themselves?
can you tell how you went about it. like how did you get it from
the trunk to the battery did you have to drill a hole to get to the
battery or what... thanks

 

I have just a box with a single ten in the trunk. The wires are easy to run. You'll have to remove the rear seat, the door trim along the bottom, pull up some carpet, and remove the panel to under the dash on the drivers side. It takes maybe a half an hour to finish it all.

 

did you have to drill a hole to get to the battery by the gas pedals?

 

Sorry, ment to add that. Yes you will have to drill a hole in the firewall. Put some epoxy or some sort of waterproofing around the hole. This is actually the toughest part is getting the drill down there, but it can be done.

 

You dont need to drill a hole. The wire is really easy to run. If you look right above the brake pedal, you will see a pipe/tubing/metal thing, running into the engine bay. Right around it is rubber isolation. Just loosen the clamp around the rubber and run the cable through that rubber isolation into the hood.

Then in the car, behind the rear seat is a gaint metal cover. Unscrew it then pry an edge with a crow bar. After you get a small gap made. Enlarge the gap using a vise grip by pulling the metal thing back.

 

It's really easy but just time consuming because you have to remove many of the interior parts to hide the wires. On the GS the battery is on the right side so I ran my power down that side. No hole needed to be drilled because there are plenty of other wires going into the cabin on that side. If you do drill remember to use a grommet to protect the wire from getting cut by the metal hole and causing a nasty short (very bad). Remove the rear seats and run the wire down the side and into the trunk. Either drill a hole to mount the ground or find an existing bolt and mount it to that keeping the lenght as short as possible. For my RCAs I ran them down the center underneath the carpet and rear seat and into the trunk to avoid any interference with the power cable.
