Has anyone heard of this problem? I've gone through three batteries in about 8 months...I took the car to an Auto Electric shop, but they couldn't figure it out. I'm making an appointment w/ the dealership but was wondering if anyone heard/experienced similar problems.

It's a 2003 Sedan, electircal after market installs include a custom speaker box and amp, and the KP window mod thing.

Oh, and after getting the car back from the Auto Electric shop yesterday, my clock no longer works. I'm hoping it's a fuse...

 

Just posting in case anyone else encounters this problem. I took my car to the dealer and they found that the problem was with the audio head unit. Having the head unit replaced.
