my remote wire had a notch out of it about 7 months back were my seats folded up and down and that caused my amp to go into protect....took me a month to find that problem....always worth a shot haha
When you did your big 3 did you sand everthing down to the metal? I have two 3000ds and they are monsters. My back batterys got disconnected from the front battery / alt and my 3000d played with my batt down to 8 volts. The amp is rock solid
no, i would say to check all of your grounds... like i told you, do an ohm check for each ground to chassis... a ground can look great, but still not have good continuity
