Alright guys, I need some input. Here's what I have : Cerwin Vega 12" 8ohm DVC sub from an old SW12B home sub. I built a sealed 1^3ft box and wired it in parallel for a 4ohm load. This sub is powered by a kicker KX120.2 amp, bridged to put out 120 watts at 4ohms. I know the sub sucks, and the amp is not a power house, but for me and my budget, its ample. Heres my problem. When playing super bass heavy music, the sub sound great, and doesn't distort, but the amp will cut off, when I turn it down, it comes back on. I likely have a bad ground, since I re-installed the rear bench before grounding and took the easy road by grounding on top of the bench mounting plate and using the nut to tighten down on the ring terminal. I didn't even bother to scrape paint.. Knowing this, I can easily fix the "problem" but I am not sure this is the "problem". Can a weak ground cause the amp to cut off at peak power? Or is my sub doing something funky? Like I said, it is not distorting at all, actually it is sounding its best when this happens. I am using a 10 gauge power lead, fused at the battery with the same amp size fuse as the amp uses. Would a heavier gauge make this go away. More notes on install.. Chevy Silverado ext. cab LS trim factory radio, using line level inputs on amp. Opinions please?
