i have two 12 cerwin vegas there new and a memphis amp ive been playing them for bout a week now until they started to go in and out could this be a ground problem
Check all your wiring, make sure it is all secure. Where is your ground at? Make sure it is free of paint for a couple inches around it, and you get good metal to metal contact. Ive had subs cut in and out and it turned out I had bad RCA's(had gotten them at walmart for my first system) when i replaced them they worked fine.
