so i got an issue with my car battery draining all the time. i’d park it for a day or so and it would need a boost. i have an aftermarket audio system with subs etc the works and a compustar alarm… along with the traditional gauges etc… kat set up with safc2. i suspect that it’s the alarm that could be draining the battery power… any suggestions? it wasnt doing this before though. ---

i’m with shawn on this one. try a new battery first and than go to all the stuff you have in there. I would also suggest that you put the sound system on it’s own battery. ---
