Rockford Fosgate Punch P1 P1S410 10-Inch 150-Watt Subwoofer - 4 Ohm
I bought two of these and put them in a ported  Box.They hit hella hard I'm running a 400 watt   Rockford amp. Had to turn bass all the way down  Got pulled over for too much bass.all in all great  Subs for the price. I Would recommend them to  Anyone looking for clear clean deep bass.
