Nope, dual 4's wired at 1-ohm final load. and i did the big 3 upgrade and tried the amp again and had the same jjump. Like i said I was bumpin at a low vol and then outta nowhere my voltage dropped to 9 back to 14.6 then kept doing it. I unhooked amp and it stopped. The alt takes the full load of a/c on, headlight on, 100rms amp full tilt, fan full speed, with no prob. doesnt even hesitate.
I double checked power for shorts and found none. I was advised by Maxxsonics not to hook amp back up or else i woulld try diff ground. I sanded sheetmetal first and everything. Thing is my ground waire is like 2 to 2 and a half foot. Idk if that plays any part but the amp worked perfectly for the few days i had it hooked up. subs are okay they still work, thats what the 100rms 2 channel is powering now.
Could my amp just be a lemon like suggected?
edit: oh and the voltage was jumping everytime the amp saw power. even with all rca's, speaker cable unplugged
