drive over to ny and i'll do it for you!

You're gonna want amps with high level (speaker) inputs, or if the amps you want dont have them, you'll need a LOC (Line Output Converter) that will transform the speaker level signal to a line level signal.

An easy way to send the audio signal from the deck to the amps in the trunk is to get some "speed wire", its a 9 conductor, color coded cable for all 4 audio channels and one wire for a remote turn on. It makes the install 10 times easier.

upgrading the stereo in your car is pretty easy... I'd say the hardest thing will be getting that beast of a deck out of the dash.
