Wobbly AND Redmx_TX5 if you're in salisbury-ish area, head to the salisbury and elizabeth cashies, they have heaps, and one of the best amps for subs ever made, Phillips XP-480, are going for about $30 - $50 last time i checked... i got one of them (the one i broke) and i have yet to find a better one for subs, they are pretty old, dont have remote bass control yada yada yada, but they are FAN-F**KING-TASTIC!...
p.s. the reason my broke was coz i had a part in the boot of my car, went around a corner, it snagged the power cable and ran it accross the speaker jacks

and i haven't replaced it yet :P...
