Figured I would post up a little "How to" seeing as how the beginning of the installation, going through the firewall, is the hardest part for some when it comes to doing an amp install.
This isn't a super detailed write up, I'm going to assume you are somewhat handy with basic tools and aren't afraid to get your hands dirty.
Ok here we go
Tools I used:
Plastic pannel tool
solder and soldering iron
Amp kit w/ RCAs
Line out converter (LOC)
Break open you shiney new amp kit. I just went with the power kit because I already had RCAs:
Take the battery cover off
All the covers come off by popping the middle of these up then pulling them out
Then take the cabin filter cover off
This gromet with the mass of wires going in it, that's where you are going to feed your power wire and any other wires you may need to run in the future. You can already see the hood pin/tach/siren wires coming out for my remote start/alarm.
Make an "X" in the rubber gromet with your knife, and feed the power wire in about 2ft.
Open the front passenger door and remove the lower trim that runs along the door sill and then the kick panel
