I have a Sundown Audio SD-2

Amazon.com: SD-2 8 D4 - Sundown Audio 8" 300W RMS Dual 4-Ohms Subwoofer: Car Electronics

And this Amp:

MTX Road Thunder RT500D Mono subwoofer amplifier — 500 watts RMS x 1 at 2 ohms at Crutchfield.com

Im wiring it like this....and it sounds like total crap.

its wired correctly. What box is the sub in?

2x it's most likely the box if you wired it right

Yeah, I cut my box wrong and ruined it. Didnt realize a little air passing through would make that big of a difference! Thanks guys. Amp install is done, but back to the drawing board on the box.
