Caps really aren't a big deal, they're just a B to mess with. You have to use resistors to partial charge and then "pop" until charged enough to put your block back on the battery. Otherwise they try to suck up all the power at once and it can be dangerous/messy. Btw, what are you powering with this amp? I'll start looking around. In this case a big 3 may help your situation too. If you have the wires laying around it can't hurt to try the cheapest routes first.
