[QUOTE="wew lad, post: 8397922, member: 665412"] Where do you have the sub amp grounded? Same size wire for power/gnd? Are you using 4 gauge CCA or OFC? I know my powerbass amp, after getting it 4 gauge OFC instead of CCA, sounded much much better. Don't underestimate the crappiness of most 4 gauge CCA, it is terrible. Mine would corrode and melt fuse blocks due to huge spikes in resistance from where the corrosion started, this was on a 1000w RMS amp, yours is rated a little higher. clipping is the easiest thing to blame... it could be your issue, but you can't say it is for sure until you ensure your amplifier is happy with the signal it's receiving, power/gnd, and the speaker wiring is proper. that amp will blow that sub, 1kw rms is a lot of power for one sub, even if the thing is rated for 1250w RMS, you're running right next to its max RMS power so you need to be conservative with the gain.
