ok I installed my sterio a couple months ago and it has been working fine till just the other day. I installed a 550 watt amp and my own sub. Well it cut out and when i checked it the red light is on ( you know the one that says there is too much power and so on) well i thought maby i blew my amp so i put my old old old one in just to check and its doing the same thing so now im thinking its the wiring some where has any of you had this problum? i even unhook the cables from the deck so its just the power, ground and ant. wires and as soon as the deck is turned on and turned down it still lights the red light instead of the green light and does nothing.....any one have any advice other than ripping all the wiring out and testing it outside the car?
