Default Where to run amp power cable from engine to cabin?

Couldn't find an FAQ or DIY on this - can someone please point me in the direction or give some pics of the best (hint easiest) to run amp power from engine to cabin (hopefully on driver side).

Thanks!
Sam

on my '04 wrx there is a large hole in the firewall on the passanger side i just ran the power cable thru the rubber grommet, then ran it underneith the side plastic running board things (sorry dont know the proper name), then ran it up to the side of the back seat, and ran it to the trunk from there. Sorry not that good a decsribbing the areas but i easily ran a 4awg wire to the trunk.

It looks like a WRX, but the concept is the same for most cars anyway.

you can run it up the driver's side.
just keep it well separated from the head unit to amp signal runs.
and by 'well separated' i mean put the signal runs on the passenger side!
:-)

i ran my power up the center 'hump', signals on passenger side, speaker wire down the appropriate side, so that my amp power would not be near any of the others.

through the rubber grommet behind the brake pedal. i cut a hole in it and passed my power cable through it. be careful when trying to put the rubber grommet back in the hole, it can be tricky to get it in the right position without popping back out.

then up the driver's side to the trunk! and run your audio cables behind the glove box and up the passenger side.

I used the same hole as the first poster. On the passenger side, towards the left there is a nice sized hole. Although mine doesn't have a grommet anymore not that it has a boost gauge line, 4 gauge power wire, and power for my gauges. And yes, IBTyou'rewiresaregoingtogetcut, I know I should do something about it mayb but its packed tight.

Like googooboy said, behind the brake pedal there is allready a precut hole with a rubber stop in it. Just pull out the rubber stop, cut a small hole in it. Best if the hole is smaller than your wire your running though. Then shove your power wire through it and now you can choose where to run it from there. I personally ran my 4 ga power wire up the drivers side. It is suprisingly easy to pop off all the panels to run the wire. No screws at all. I ran my Audio cables up the center console. Its best if you run your audio cables in a different spot than your power to prevent any noise. I recommend pulling the back seat (actuall sitting part not the back rest) it makes it a lot easier to pass the wires. Only 2 bolts holding it in, and very easy to reinstall it.
