My friend got 2 of these in his single cab truck and they hit much lower and harder than any subs Iv heard in his truck. After hearing them i got on sonic and ordered one and a box to go with it. I put it in my single cab truck, and wow it is so much better than the pioneer i had in there before. The amp i have is a to powerful so i cant crank it up all the way, but ordered a new fosgate amp to go with it so hopefully ill be able to turn up the volume!

I love these subs! I have two in a single cab f150 and they SLAM. They are being pushed by a 1000w monoblock and in a shallow wedgebox. I would have so many tickets if it wasn't for the mute button on my headunit. Not only does this sub have bass, but you can hear the sound.

Good quality product, gets the job done with less power and fewer speakers with the same punch.

This sub pounds! I have one bridged off an infinity 7520a amp at 283RMS and it hits for a single 12" woofer. The clarity is amazing! I would recommend this to anyone that wants good clear crisp bass.
