Check in line fuse, make sure you have a good ground, and make sure the remote turn on wire is connected to a 12v power supply that only comes on when your car is on (that wire sends a signal to your amp telling it when to turn on and off.

Stereo remote wire won't power on amp sony mex


The easiest check is unhook the remote turn on wire from the amp and use a small jump wire to bridge the 12dvc input of the amp and the remote turn on connector of the amp. If the amp powers on there is an issue with the remote turn on connection either a bad wire or bad output. If the amp doesn't turn on there is an issue in the amp wiring or the amp itself.

The amplifier light keeps turning off, then on which leaves me with no power for my subwoofer. This usually happens when I turn up the music in my car. The base would go away, then come back constantly...


Hi,

This problem is due to over powering the speaker. Amps have built in protection for both themselves and the speakers they are connected to. If you have the gain turned up too far on the amp, it can cause the amp to go into protection mode which will turn the amp off temporarily. You have probably noticed the speakers make odd noises or sound awful just before the amp turns off. Other issues may be that you have a bad ground connection to the amp. Check this connection at the amp and at the location the amp is grounded to. Follow the "-" or "GND" cable from the amp. if that connection is good, just turn down the "gain" dial on the amp about 1/4 and turn up the volume and see what happens.

Amp turns off


Sounds like remote turn on wire is bad. If using aftermarket HU, find another location to power amp. Try the the power antenna wire on the HU to run the REM.

You may have the amp set to turn on via an audio signal. Set the Signal Sensing switch to OFF.

Jl; audio 500 amp


I assume the signal sensing switch you are talking about is the remote turn on for the amp. The amp should turn on when you turn your radio on, not your truck.
First try disconnecting the remote turn on that comes from your radio. After that is removed turn your radio on and them run a jumper wire from the positive voltage terminal of the amp ( the main power input) to the remote turn on terminal of the amp. If the amp turns on and you hear music, you have a problem with the remote turn on from the radio. If the amp turns on but you hear no music you have a problem with the audio input of the amp or the wiring of the speakers. if the amp does not turn on you have a problem with the amp.
I think you may have a problem with the remote turn on output of your radio. if so, you need to get the radio looked at by a service technician.
If the amp is turning on sometimes, you may just have a loose wire or faulty ground. Double check all the wiring.

Visonik amps turn on into protection mode(where green not red for three days)...switched over the wires to some sony amps and they dont even turn the hell on


the fuze could be blown on the amp or the speakers are to much power for the amp at full power so try to turn the amp to half and not to turn the speakers all the way up,.
