I got my mind made up and I'm going with either the XXX 12 or 10" sub. Anyways, I was wondering if this amp is too much for these subs, good enough, or what. I'm slowly building a really nice system and I don't mind spending extra if I get a solid product. Anyways, are there any other amps that I should consider? I was going to go with Zapco, but the price is a little too steep hehe. Any input is appreciated. Also, is there anywhere other than Rainarc that sells these amps? Thanks in advance.
