Good luck finding a decent amp that has enough power to power those two subs, at least under 140 bucks, your best bet is to go to a pawn shop or go get the latest wal mart special, i say just spend a couple extra bucks and get a good one, i have a 3000 watt boss amp and it powers my two type r10s really good, really loud, those are not that expensive looking at like 250 for a new one, or look on ebay for a used one.
