[QUOTE="brice15s, post: 8837111, member: 688602"] Hello, I've had a Kenwood-511 1000w amp powering a single Memphis Audio MJP1522 15in sub (750watt RMS) for a couple years now. never had any issues, could crank it all the way to max without clipping or it cutting off. Now I'm looking to upgrade to a bigger amp, and add another 15in sub. The new amp I have is the Pioneer GM-DX971 which is stable at 1ohm 1200w rms. I wanted test it on my current single sub before pulling the trigger on another sub and a ported box. The issue I'm having is that when I get past about 35-40% volume, it cuts out. I've been trying everything to diagnose, upgraded my power and ground to 4 gauge, re-wired the sub down to 4ohm (amp can do 500w at 4ohm) and I'm still getting the same results. I currently drive a 08 civic with a stock 80amp alternator, the alternator is the only thing I can think of that I havnt tested, but I get very minimal dimming when running full blast on the old 1000w amp, so Im just not 100% this is the issue. So figured id post here to get other opinions of people more experienced than I. Thank you edit: the new amp is 2400W Max [/QUOTE]
