How much thump thump you got in your bump bump? lol I tought I had a crappy HU and Amp, but I only turn my HU up to 10 (it can go to 30) and the seats are shakn' like crazy, I can't see out of the side mirrors or the rearview mirror, and it's just deafning. Believe it or not I have a Pioneer DEH-27MP (someone gave it to me, so I didn't complain!) a Jensen 220W MAX, yes MAX, and one 12" MA Audio Sub with 1000W peak. I also have a Low Pass crossover on the sub, (how well do those actually work, does anyone know?) and this setup is great, but I'm upgrading. I'm lookn at a Kicker 12" and a 300W RMS amp. I was lookn at Radio Shack and the salesman and I went to the sealed off room and messed around with different setups of subs hooked up to a 1000w amp. The Rockford Fosgate was 12" in a ported box, nutn great at all, there was one Alpine 12" in like a $600 box, that blasted away EVERYTHING! then 2 12" Kickers in a ported box and the Kickers sounded SOOOOOOOO much better than the Rockford!
