Amp / Voltage draw issue.

[robbz28]

I have a problem and I wanted to just throw this out there before I break my multi-meter out and start poking around on the car. I have something, somewhere sucking the life out of my battery over the course of a week. I thought maybe I had a bad battery, took it to Autozone today and they tested it and said all's well. So are there any "usual suspects" as far as these cars go with this issue? I know my dome lights, under-hood lights, courtesey lights, and glove box lights are in working order. The radio is stock, but there is an aftermarket amplifer wired in to replace the bose speakers, but the power light on it is off when the car is. Maybe a stuck relay or something?? Where to start? What to do? My little 1.5 amp battery charger stays on it in the meantime.
