[quote name='seattle968' post='37667' date='Jun 30 2007, 12:48 AM']I'm thinking about installing an amplifier in my coupe (probably in one of the rear cargo area cubby spaces). I'm wondering what is the best route to get the power supply lead to the battery?

Tap off of the factory wiring behind the radio. There are two 12V leads - one switched with the ignition and one hot all the time - you'll want the switched lead. IIRC, it is the Geen with Red stripe. Solid Red is the hot lead. Also, if you have an aftermarket head unit, it may provide for "remote power" which will supply 12V when the head unit is on...exactly what it is designed for is external amps and powered subs.
If you need a direct battery connection, getting out through the firewall isn't a huge deal and it can be done on either driver or passenger side. Driver side has some paths under the steering wheel and passenger side would be done behind the glove box area.
Hope that helps!
