Your sound system probably is not draining your battery.
it's likely an old battery, or a door or glove box ajar, or bad alternator, or alternator belt.
The Ultima battery is one of the better batteries out there: http://www.optimabatteries.com/publish/optima/americas0/en/config/product_info/automotive.html
Available at autozone, Sears etc.
I've always had good luck with Sears international die hard. other people swear by the BMW batteries. Depends on how much you want to spend.
However you should find the real cause of your battery drainage. _________________ Lachssilber Metallic 203 1988 325i sedan with 200,xxx miles

An 04 325is? the guy is in the wrong forum =)
When I had bad battery, hte car was stalling when I drove right away after starting. The batt was always low and used all power from the generator trying to charge.
Any battery should work wine anyway.
1) see if it's charging - use multimeter on battery with engine running,,, should be around 15+ wolts. (not sure if those new cars have violtmeters gauge in them)
2) see if it holds - check voltage with engine off. <12V =not good.
or screw all that just go to autozone and say you want to get your battery and alternator tested
3) when you connect and disconnect ground terminal - is there a spark present? If yes, that means something is turned on.
3) to illuminate sound system try pulling the proper fuse out and see if it helps. _________________
