It probably has shorted output transistors. Read through the following page to eliminate other possible causes. Let me know if you have any other questions.

Protect light comes on, no power


Hello patrick_h_mi,

You'll also need a remote turn-on source for the amp to operate. Normally, this is a blue or blue/white wire from your head unit, but for test purposes, you just need 12V to the "remote" terminal on the amp. The amp should power up without speaker inputs or speaker connections, but it is not recommended.

Hope this helps.

Amp not working


Does it do the same thing if you remove the RCA input and disconnect the wires from the speaker terminals of the amp?

On and off


Hi.
Take the input leads out of the amplifier for a start, but leave the power and remote cables connected.
See if it still turns on and off. If still faulty, you have probably blown a power transistor inside and the amp is shutting down when the output rises each time. It will almost certainly need looking at. Also make sure you are running into the correct impedance load. If you have hooked up too many speakers you will cause damage.

Protect light flashing/ticking


this problem sound like you have too low of power going to your amp, test your battery and make sure its putting out enough power for at least the mininum amount of power that your amp requires, you can find that information in your manual or sometimes they post it on the amp itself. i hope this info helps

No sound


I would try it without the slot for the additional amp. However, there is a chance that it is fried. When its powering up I would check the voltages with a multimeter to make sure everything there is in order.

Clip light


A shorted speaker, a pinched speaker wire or a short in the amp, itself. Try to disconnect the speaker wire from the amp. Did the clip light go out? No?? Ok take out the amp and send it to the service center as unless your a tech, there are no user serviceable parts inside as its all solid state. Good Luck
