I have 2 10" 4 OHMS Type R's in a sealed box, now the guy that made the box said that the amp I have (Sony XM - 1502SX, stats below) would not have enough power but it seems to pound pretty good. Do I need a different amp and if so what kind in a $0.00 - $500.00 budget.

Maybe not enough to power them to their full capability, but it's enough power to make them play, now isn't it ?

You don't really need a new amp, but if you want a new amp, any reliable amplifier that puts out 600-800 RMS @ whatever the final ohm load of your Type-Rs is would be the best choice ...

Well they sound good enough for now, but if I were ever to go in a comp I would want more power. Also what is a good bass CD, I currently have Food for Woofers 3 wich does the trick and various **** off the net but I need a real bass cd with good low hard pounding bass, mmmmmm shake, no rattle and pound.

if you feel you need more you could buy one more sony amp and run 1 per sub bridged ......
