My 12" eclpise subwoofers seem to be clipping or just going nuts when i start the car and the volume is off and i turn it up passed 0 it clips, then when i have the lp filter on they seem to be getting crazy feedback from the deck, and i need to turn it up for it to sound good, the amp i am running is a Rockford Fosgate 500a2. also when i turn the hp on it quiet's right down with the unessesary horrible sounding clipping.
and the subs are 175rms a piece 300 watt max, eclipse.
