Green light on amp?? Seems like your amp is going into thermal overload. Check your power connections, and make sure there are no shorted wires. Hope this helps.

could be the speaker its hooked up to . try to disconnect the sub and see if the protect light goes out

1. check power supply
2. check flyback

Ether or you have a ppower fauilure in the unit. and its probably blowing fuses.

Power supply is the place to look, look for bulging on top of the capacitors in the secondary side of the main power supply.

its probably wires touchin or the ground not connected well with fat enough wire. i would try to rewire and do everything all over again because one wire or fuse is messing up i had t he same probelm. its the red light on the amp is ur amp shut off or ur warning light?

The amp should always light up showing you that it is powered and there will also be a red light that will light up if theres something wrong.Sounds like maybe the hot wire that goes to the amp isnt big enough to give the amp enough power.Check your positive wire and ground wire for tightness and make sure hot wire supply is big enough and also the ground wire is big enough and has a good ground.I hope this Helps you.Have A great day..

make sure the turn-on wires wasn't accidently disconneted

Either the amp is ad or the sub got shorted? You can check itby disconnecting the Sub and seeing if the amp comes on blue then. If yes, then the sub is shorted. If no, then the amp is shorted. Also chck the voltage AT THE AMP. Make sure that it is above 12 Volts.

The person(s) who hooked up your system made a boo boo. They wired your remote turn on lead to the power antenna lead instead of the amp turn on line (both are blue and easy to mix up). Thus when your radio is on it sends a signal to the amp and the amp turns on, but when you set to CD the signal goes away and your amp shuts down. Easy fix, just re-wire the amp turn on lead and the problem will be fixed.
