So I got a new car and put my old setup in (skar lp1000 monoblock, Jensen w12 4 ohm single coil, 4 gauge), whenever I turn up the volume slightly my amp goes to protect. Multimeter says battery isn't dropping voltage but when I check at the amp I can drop from 12 to 9.5 on a small bump, ground and all wiring is fine. Battery not discharging fast enough maybe? Would adding a second small battery help with this? Really can't figure this one out.
