well I bought and installed a yellow top battery, and ofcourse my sound system still doesn't get enough power. Now it has a different problem! In the middle of a song, no matter what song, the power suddenly cuts off. As if the power cuts off to 10%, and then trys to regain power again. It's really weird, I dunno if it's the battery or the RCA connection. Arg, this sound system is frustrating as hell, in the end it'll cost more to maintain it than the sound system itself!
