These subs are fantastic for someone looking to hit at a low power setup, once I bridged the amp it always went into protection mode and finally after about a month the amp gave out and fried, so Sonic is sending me a new one and im installing a fan on it also. but I plan to sell the 2 12's and buy one 15 to run off the amp. but I would recommend these for someone that just wants that extra bass, but if you want to really flex, I would stay away.
