  • I love this sub! I'm pushing it with a JL 500/1 amp and it kicks ass. Sounds just like JL sub but lots less $$$.

  • Best sub for the price, hits very hard, one of these will rattle your whole car, they are unbelivable when installed in a transmission line box.

  • This sub is awesome!! Smooth, clean bass for a great price. 2 of these subs would be great for an SQ setup, (which is what I have in a BMW 330i), but 3 of these for an SPL setup will blow your eardrums, (which my buddy has in a Ford SVT Lightning). You CANNOT get a sub that performs like this one for the price!!!
