As an aid to your install you can get the schematic for your system at the following link:

If it is a 96 and you have 2 amps by the stock sub, one is for the sub, and the other is for the radio. If you remove it, you will have no sound. Use that schematic and hook in with a line level converter from one of the speaker sets, then run a power, ground, and a switched lead.

Or you can also just splice rca cables right into the speaker wires for the stereo. It's free and works fine.
