Check your ohm load from your sub... that's generally the problem causing protection lights to kick on or the amp to shut down.

My sub has all bin wired up proberly the sub works for about 30 secs then the green light goes out and no power to the sub at all


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.

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

Basicly my speakers were working fine, my subs were working fine but everytime i was turning my volume up to a certain level i would lose all base and all noise from the subs in my boot, so i turned it...


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..

Kenwood KAC-8401 light goes from blue to red when turned on


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.

My amp only powers the subwoofer when the radio is on but wont when the cd player is on


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.
