Just what the question says. When it's cold outside, my amp turns on and everything works like a charm. But now that it is warming up, the past week or so my amp has been being a bitch and won't even turn on at. i have two kicker 12 inch CVR's and a kicker ZX750.1 amp. with 4 gauge wiring if it matters any. Please, this problem is REALLY starting to annoy me. Thanks
