Is the main power wire going directly to the battery? does it do it under load only, or all the time.
Disconnect the RCA inputs and see if it continues to do it. if it still does it, then disconnect one speaker at a time, if it is still turning on/off with no speakers and no input, and has 12V direct from the battery, then it is faulty and will need service.
If it only does it under load, get a multimeter and check that the speaker wires are 4-6 ohms between them, also check from each speaker to body of car, there should be no connection.

The lights on my amp are not on


Check your fuses! Then check your remote turn on wire from your head unit and make sure it's sending a 12v signal out to the amp, you can also jumper a wire from the + connection for the power wire over to the turn on remote wire connection and see if it powers up. If not, then test for voltage at the amp connection, + & - should have no less than 12 volts to get that amp to turn on and it will require a constant 11.5 volts even at full volume to keep it from being damaged by under voltage or under amperage. If you have voltage at the amp then I would smell the amp to see if it has that burnt component smell that accompanies most amp failures. If it smells like smoke it's in need of repair to the power supply, check maufacturers warranty and have it fixed.

What size wire should i have for two 12 volfenhag subs


I would use 10 to 12 gauge wiring. As fare as your amp's fuse...Check to make sure you are using the correct amp fuse. Make sure your subs are wired to a ohm load your amp is stable with. Check your ground and positive connections. Check and make sure your amp's gain settings are correctly set. Your amp's gain should not be turned all the way up.

It keeps blowing my fuse for my stock radio. Pushing a 10" sub.. Fuse on my amp is good. In-line fuse is good. But it keeps blowing the radio fuse in my panel.. ? Please help.. Thanks Ryan


Check the amp turn-on wire. It's a blue/white wire running from the radio to the amp. It's probably label REM at the amp. This wire sends a switched 12 volts from the radio to the amp. It is probably shorting out somewhere between the radio and the amp.

Amp light comes on briefly when car turns on but dims out right away. Whats the problem i have checked all wires numerous times.


first make sure your remote wire is hooked to amp turn on wire not power antenna wire if head unit has both wires or if you have multiple amps you may need to put a relay in line to help keep voltage steady

Amp keeps turnning off say to check speaker wires but speaker wires all ok i think


The amp turning off means you've got a shorted output, so I'd unplug your speakers, unplug the wires, etc, then plug it all back in, paying attention to the wires and where they're going.

3amp fuse keeps burning out


Hi,

when a fuse blows, its telling you that theres a fault. this could be a loose or broken wire.
or alternatively, the fuse rating is too low. you could check the wires are tight. and also possibly try fitting a 5 amp fuse. check first that the fuse is rated correctly for the appliance. usually 3-5 or 13 Amps.

My amp wont turn on


The reason it used to cut-off at 60% volume as you said before,
Is probably due to the "protection circuit mode" being tripped.

You can try resetting it by turning off your CD player ,removing the Batt( + ) and Gnd ( - ) terminals from the amp for a short period. Reconnect them Allow the amp to receive power but not switch on (keep cd player/remote power source off)

If you dont know how to wire the CD player to control the amps power status , the easiest way is to connect the 'power antenna' or similar low voltage throughput wire from the head-unit to the amp's Remote terminal.

My old amp did the same thing ,and would need to be powered off/on before resuming sound output, sometimes I had lots of trouble with the protect mode staying on , even with little or no sound output from headunit.

My Power Protector Light wont turn Green


switch off the amp then take off all the wires off including the speaker wire and then reconnect the wires on like before the problem is that the amp is on protection and if that dont work then get it repaired another thing is make sure ur amp fuses havent blown.

Keeps swirching to protect mode


First thing to do is disconnect all of the speaker wires on the amp. Turn on the amp, if it is still turning on and off then there is a definant problem in the amp circuitry. If you have no solid state service skills, I highly advise you to take the amp into a repair shop. If it stops turning on and off turn off the amp and try and connect up one speaker at a time untill the amp starts to mess up. you then take that speaker and have it checked out and inspect the wireing for pinchs or shorts.
