Better than the best!

I bought 2 put them in a sealed box with about 500 watts each in my full sized SUV (cea rated 500 watts each) and OMG! The window and body waved! Very deep, very clear and they punch so hard I can not only feel it, you can SEE it! Wow !

Holly cow these things BANG!!!!

So I ordered two of these to replace the Polk Audio PSW505's that I have. I had a local car audio shop build matching boxes that where the exact dimensions from the factory specs (2.75 cubic feet and tuned to 28hz). I used the 300 continuous watts plate amps from the PSW505's and they power them perfectly. Once I hooked them up, I realized quite quickly that I needed to start rattle proofing the entire theater room. The PSW505's didn't shake much of anything in the room, these just about knocked the lights off the damn wall, and that is using the exact same power supply for both pairs. I LOVE THESE SUBS!!!!!!
