Great value
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.

alright for the price.
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.
