if you really think that the sound system is causing it i would disconnect the system to see if it has any effect. you can also try to diagnose the problem with a multimeter(if the drain isnt strong enough to light a test light) to measure amperage draw between the battery negative and ground like with test light. if you do see an amperage draw then 1 by 1 pull fuses from the fuse box til you the amperage draw disappear then youve pin pointed battery drain is coming from.
I'll do that.

A couple things:
1) your ground(s) should be way less than 1 ohm.
2) your battery drain could happen if the amp(s) are not shutting off when
the remote wire from the headunit turns off. You could check this by removing the
fuse to the amps when all is off, and then putting your multimeter on them set to
"DC amps" and seeing if there is current flowing.
