Questions about amplifier install.
I finally broke down and bought a new Alpine Head unit with Ipod interface and a set of Alpine Component Speakers for the front doors. I was able to install everything myself but the components are not getting enough power and now I need an amplifier.
Does anyone know of a good walkthrough with pictures about installing an amplifier in the WRX? I plan on putting it under the passenger seat to power just the front speakers and i'm not sure of the best place to go through the firewall to the engine.
Also when running wire to the crossovers in the door should I bother with trying to run new wire or just splice into the existing wiring in the kick panel that they are already attached to?

Never mind, I figured it out myself. Installing an amplifier basically sucks. I'm surprised the car stereo place only charges 50.00 to do it. Now I have to save up for a sub or acquire a taste for classical music.

As far as your wiring goes, How many watts(rms) are your speakers? Stock speaker wire is rather small, so if you are going to be runing 100 watts off of a wire that has what...15w speakers....you are going to cause some major resistance. which leads to crappy sound.
Are you set on keeping your crossovers in the doors? Its not the greatest place for such a delicate instrument. Rain and vibration arent exactly good for them.
Placing them under the seat near your amp would make tuning your system easier. Than you could just run some nice bi-wire
Where did you mount your tweeters? Mouting them on the a pillers allows you to avoid running 2 sets of wires into the door, and is also said to be the best place for imaging.
Good luck with your system!

through firewall?
Just curious on how to get through the firewall the easiest. Is there a point at which you can just get the wires through a factory wiring grommet? I imagine they make the opening just to accomodate the factory wiring, and it's hard to get any wires through. I am planning a three amp setup, and will need a pretty big opening. I'd appreciate any tips on the best spot for the wires to go through.

I know that there's a grommet right under the edge of the carpet beneath the break pedal with a hole wide enough for even the beefiest wiring. When I install my amp. I'd like to pop the grommet out, drill a hole through it, run the wire through the hole and pop it back in. What I'd like to know is how to get that grommet out? Push from the inside out? the outisde in? twist? I'm sure some of you have done this before, anybody care to share?

Just did all this in my saab 9-2x with 0/1 gauge, and i have an amp under each seat. run power wires down drivers side through hole by brake pedal like suggested. then down the center console with the RCA's and under the carpet to the amps and poke them out the vent hole that's already cut. keep power wires under the carpet too, it's easy. Then, for ground unbolt a seat sand off the paint and attach it to that bolt. Everything in mine was run under carpet and completely invisible, works very well.
