I got two of these in a ported box recently and I'm thoroughly impressed. Even with only 160W going to each (4ohm load on an R500-1) they really pound, much much louder than my 2 old Kicker CVR102s. Only thing I regret is the fact that I overpaid by about $100 by going through the local car audio retailer instead of just buying everything here. Regardless, I'm completely satisfied with these subwoofers.

These 12s have 250 Rms and with a well powered sub u can get some descent sound from them. I have 2 of them connected to a 1200 wat pyle amp and they have lasted for over a yr without a problem, and now I have just one connected to the amp and it hasnt overpowered of blew so its a very solid sub.
