When I turn it up the amp shuts off and I have to turn it down and then it comes back on. Check your grounds. I already have my ground is fine Alright well until you get a dmm and post back your voltage drop at full tilt, we can't really help that much alright
I have a 12" bl with a kicker zx1000.1 and an optima red top for a battery and even with the gain only half way up I am getting headlight dimming and my amp is clipping. I have a friend with the same amp and the 15" bl and his doesn't clip and he has a weaker battery so I have no idea why mine keeps clipping.
