Very likely the amp is overloaded and goes into protective thermal shutdown. Letting it cool off for a little while would allow it to reset. could be it's not capable of sustained power level you like. Next most likely reason is miswiring speakers - if you have more than one and they are in parallel (the usual case, with all the red+ terminals wired together and all of the black- terminals wired together), check to see that their total impedance is no less than the minimum specified in the amp's manual. The total impedance is Z=1/(1/Z1)+(1/Z2)+(1/Z3)... where Z1 is the impedance of the first speaker, Z2 the second, etc. For example, two 4 ohm speakers in parallel = 2 ohms.

are you using more than one amplifier? it sounds like you may be using the blue wire to turn one amp and and the blue/white to turn the other one on. use the blue/white only. the blue wire is antenna remote and turns off when not in tuner mode.

Hi i turn the amp on and the green light turns on but no sound comes out from the sub


You need to check the wiring of the sub or the box. If you have done that successfully than look at the rca cables and the blue antenna wire running from your deck to your amp

When the radio is on the sound comes out of all the speakers. when the cd player is on the sound only comes out of the sub woofer


are you running separate amps for the woofer and speakers??? sounds like you have the woofer amp being turned on be the amp remote wire (blue/white) and the speaker amp turned on with the power antenna remote wire (blue). if this is the case you need to use the blue/white to turn both amps on.

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..

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.
