Either an external or internal fuse is blown on the amp or the fuse by the battery is blown. If that's not the case your amp is done

I have a pioneer GM-X524 amp connected to a TS-W253C subwoofer and it isn't working. It has 12v power to it and a solid ground, but the power light wont come on and the sub isnt working


there should be 3 power related cables connected to the amplifier:

1-From battery to amp via fuse (positive)
2-From chassis of car to amplifier (negative)
3-From head units (power continuous) (blue or blue/white cable) to the amplifiers remote connection.
this connection enables the amplifier to switch on when the head unit is switched on and off when the headunit is switched off.
I hope this helps and let me know if I can further assist you.

My power acoustic protection light stays on i got good ground and a good positive connection, no speakers or RCA's hooked up, what could it be


Are you fused close to the battery with a 30-50 amp fuse block?
Ground unit also to most closest suitable location!
Is your power wire undersized?
Check units fuses you may have blown one hooking it up!!
Good luck

My kenwood amp wont turn on all the way i just hooked it up to my truck. the blue lights and the fan come on but the red light wont come on to power my subs


REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL DOES NOT POWER UP, VERIFY THAT THE POSITIVE AND ESPECIALLY THE GROUND CONNECTIONS, ALONG WITH THE REMOTE CONNECTIONS ARE 100%, THEN TRY AGAIN. IF STILL NOT POWERED UP, MEASURE THE REMOTE WIRE VOLTAGE TO INSURE THAT IT IS NOT LOWER THAN 11 VOLTS. IF YOU CANNOT MEASURE IT, THEN DISCONNECT THE REMOTE LEAD FROM THE AMPLIFIER AND TEMPORARILY INSTALL A JUMPER WIRE FROM THE POSITIVE POWER TERMINAL TO THE AMPS REMOTE TERMINAL WHICH WILL FORCE IT TO TURN ON. IF IS STILL DOES NOT POWER UP, THEN IT WILL HAVE TO BE SERVICED. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

Amp gets power but doesnt send anything through speaker wire


There are several things that could cause this that i know of, bad ground not being one of them.
A bad ground terminal should cause a noticeable distortion in sound and cause the amplifier to turn on and off.
If you are getting power and no sound, the first and easiest thing i would check is your RCA wires. Replace them with known good wires.
If that does not work, are you positive the speakers you have hooked up to your amplifier are not blown?
If available, use a DVOM to check resistances on the coils on your speakers. An open lead reading indicates a blown voice coil.
Also make sure that your speakers are each hooked up to a positive and negative terminal, as some amplifiers have two positives next to each other and two negatives, while others go + - + -.
Your amplifier could also have bad input or outputs, but i would try these other easy fixes before resorting to buying a replacement amplifier.
The only other cause to my knowledge would be bad RCA outputs on your head unit.
If possible try with a head unit you know the outputs work on.

Hopefully one of these suggestions solves your problem.

Have you connected the remote wire from the stereo to the amp? assuming it has one.
If the stereo has not got a remote wire you can link it from the positive 12 volt on the amp to the remote connection on the amp, usually it's in between the ground connector and the 12volt.
