I to am expieriencing this battery problem with my 05 coupe. I have replaced the stock Shaker 500 HU with a Pioneer AVIC Z3, replaced the stock battery with red top Optima, and the stock alternator with a PA Performance 130amp alternator. Still cant leave the car for more than 14-15 hours without the battery draining enough that nothing will work. That is even with driving for several hours at times prior to parking. I am going to local stereo shop in the am to try to trace the power draw down. I may also upgrade wiring from alternator to a 0 gauge wire, and upgrade factory ground to 4 gauge. Will report back in a few. Will have the shop look at the radio fuse and fog light relay though.
