Hello, I have been looking around for possibly better subs. I currently have a set of 12" Pyramid Imperials DVC 4ohm subs rated 1200peak 600RMS.. I keep getting told that the rockford fosgate P3D412's would hit harder.. but they are rated 1000peak 500rms. Also since Im sorta newbie on how to pick subs.. I thought the higher the DB sensitivy the better? The rockford subs have 85db sensitivy where as my Imperials have 97. Right now I am putting about 250watt rms to each of my subs and they are...

A: i would say start with a better amp....then try the other subs. but they may not be any better depending on their specs/setup. IE. awesome subs in a shi**y box vs. so-so subs in a built to spec tuned box, the *lesser* system would sound better. also if u are not giving your subs full power then they are not giving you full output.

I have a Pyramid 450w amp, a Pyramid crossover unit, Alpine headunit, and a 1200w 600rms Boss subwoofer. At low volumes it sounds real good and hits. But when i try to turn up the subwoofer setting or just volume on my headunit, it starts soundin bad and makin a poppin, crackling sound when it suppose to hit but sounds ok when just holding out a note. I know its not blown though. So what could be the problem?

A: It is probably NOT the sub cone but the enclosure -- at least that's how it sounds. Could be as simple as a screw not tightened all the way, or a small crack in the frame. Just go with the less expensive way first and check the cheap stuff like that before you get too worried about the electronics, especially if sustained low dynamics are clean and distortion-free...

Good Luck... :)

I have a 12 inch lightning subwoofer, but I found a 400 watt pyramid brand AMP...will it work with my subwoofer???????

A: It doesn't matter. They are both junk brands anyway. If it blows it, buy a better sub.
