Ok i think you might be lucky, i just had this problem for like 2 months.........k with your cd player on, get a multimeter turn it to DC volts, put the black probe on the ground of the amp and touch the red the power or remote, if its under 11 volts you found it....most likely its the fuse right off the battery check it at the far side with the multimeter......hopefully this helps

MAKE SURE YOUR GROUND WIRE IS GROUNDED GOOD,,AND IT IS IMPORTENT TO HAVE YOUR REMOTE WIRE HOOKED UP. IT WILL BE A BLUE WIRE,,FIND THE HOT WIRE FOR YOUR TAIL LIGHTS AND HOOK IT THERE THEN WHEN YOU TURN YOUR CAR ON THE AMP WILL ALSO COME ON.THAT SHOULD STOP ALL THE NOISE AND POWER YOU UP.

Only one channel is puttin out sound and its vary low power i have checked all the connections and they are all hooked up right any idea on what the problem(s) could be?


Try checking the fuses... How Many amps is the fuses u are using ? most of the time it is best to match the fuses with the amplifiers output. check the fuses also to see if any are blown or broken, or the nobs on the amp. there are controls on the amp u set to putout the amount of bass u want and other setting u want your amp to be set at.

Hope this helps.

Check the fuse sometimes when hooking them up youll blow a fuse.but make sure your ground is to bare metal no paint should be on it. very important.. also make sure the blue wire has current using a light tester or volt meter. if you have a long wire run it directly from battery to see if its the remote wire . sounds like a bad ground is the amp new what is the brand

My amps not working anymore.


first check your ground wire then you power wire connections .. check the fuse to see if its making connections on both ends of the wires..


i think the flickering is the result of a weak or bad connection in the power ground or acc wire "normaly blue"
your amp has no sound because the amp has to charge before it can out put at a higher amperage


hope this helps

Dont know whats wrong


You can check the fuses if it has more than one. Or another thing that might be wrong is that you might have to big of a speaker hooked up. Or your power wire might be to small because if its two small then the amp cant get enough power to power a big speaker.

No audio-amp protect light come on then went


You need to check the DC voltage across the B+ and ground terminals. You also need to check the DC voltage across the remote and ground terminals. If the voltage is less than 11 volts, you need to check the B+ supply and remote wiring for breaks or open fuses. You should also check the ground connection to confirm that it's not loose.

 

If the voltage is OK, the output transistors are likely shorted.
