I have a JBL1004 amp in my ski boat. I killed the battery listening to the stereo and caused the battery to lose a cell and drop to 10 volts. The stereo cut out as one would expect. I have replaced the...


if the protect light comes on then you might not have enough voltage running to the amp so you would need to add a second battery just for that amp.

My sony xplod 1200 whatt amps red light keeps coming on all the wires are good when it gos to hit it gos red


check your ohm load on the sub and see if your amp can do the same, That is why every time it shuts off into protection mode. Check your gain level on the amp to this is not a volume knob for your amp, It is to get both the amp and cd player on the same page. Hope this was helpfull

I would check to see if the vehicle came equipped with a stock amplifier sometimes the wiring comes loose from there or the amp just simply gives up.

My jcpower car amplifier is not sound come out


you are probably getting a high voltage jump when you turn it up which will throw the amp into protect mode the only thing I can think of is trying a voltage regulator for your stereo

My amp turns on and off


Sounds like there could be a short somewhere. Check to make sure that there aren't any (exposed/bare) wires touching each other or if there is a bare spot of wire touching something metal. Check both ends of all the wires. A speaker wire may have come lose and is shorting out against the frame or some other place. Usually if it goes straight into protection mode or you're popping fuses you have a short somewhere. I assume the capacitor you installed is somewhere on the power line, which would be for helping with
noise. You can also try disconnecting your amp from your stereo and see what happens but leave the speakers connected, you don't want to run the amp with out a load on it (the speakers). If your amp doesn't go into protection mode when the stereo is disconnected, then you have a problem with the stereo and not the amp, assuming you already checked for any possible shorts first.

Amp in protection mode


Disconnect all speaker wires and signal cables from the amp. If it powers up normally (doesn't go into protection), the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
