1 pointYou were right on point. Fixed it, so I end up buying a small voltmeter to permanently wire to the amp power terminals. When bass hit, it dropped way below 12v from 14v. So I sanded and tightened the battery terminals. The biggest thing that I think helped was that I had a 2 foot ground going to a large bolt on the frame, so I re-sanded it, and jumped another foot 2AWG from that bolt to another. Now everything seems to be running fine. Gain is at 60 - 70% no problem, no clipping or cutting.
