Battery Drain! HELP!

Hey everyone I have a 1995 BMW 325i. I'm having an issue with the battery draining while sitting idle (not started) for 6+ hours. I have to 10" sub woofers that I think may be draining the battery and was wondering if a capacitor would help or is there a bigger issue?

The function of a capacitor is to store energy and quickly release it upon demand. That has nothing to do with the battery draining.

Now are we talkin, "I am boomin the tunes all day and the battery goes dead" OR "The battery goes dead overnight with everything shut off"?

If it is going dead overnight, start disconnecting things one at a time to try and isolate the drain. This also may get better play in the e36 forum as their wiring is different than ours.

This doesn't make sense. Idling is when the engine IS started.

If you think the batt is being drained see this thread:

Thats why I asked. He does say idle, not idlling
