dumb azz, they are no good. thats why they are cheap. I would keep checking ebay if your tight on cash. Kicker choice will be way better than pyle or pyramid! Since u got the JL sub, I would save up and get the JL amp. just wait..... I know its hard.
the JL 500/1 would be perfect but you could go w/ the kicker 600.1 which will over be powering the sub a little if it is the 12 or 13 it should be fine though. not sure if there are still new ones available but a good solid 500 watt amp was the rockford bd500.1 they were a good quality amp some of the better rockford amps over the last few years.
