BTW, the yellow top kicks some serious butt. I run my stereo at full blast all the time while I'm playing bball or cleaning my carport or whatever and the battery has never died or failed to start, even after 4 hours of constant use. The biggest problem is my amp overheating after a while. Guess its time to add some fans.

My neighbor is runing a 15 farad cap off a stock battery and alternator and it only lasts a few minutes before the battery is dead.
