Protect mode would indicate that the system is shutting down due to a fault in the output which drives the speakers. You can check the speaker wiring, are there an loose or frayed wires? Any small "whiskers" or wire touching anything? Check the wire all the way to the speaker for damage, some pets love to chew wires! Are you using the original speakers or added extra? The impedance of the speakers must be in the range shown on the back of the unit. Have you perhaps had the volume up very high? This could result in speaker damage that could also cause this error. Try disconnecting the speakers & see if the unit powers up, if it does then put the speakers back one at a time to discover the faulty one. If all this checks out OK then the output stage itself is probably faulty & that's a job for the repair shop. Please update the question & let us know if the information given was useful to you - Good Luck!

My jbl stereo wont turn on. when i turn my truck on it just lights up and then goes straight back off

Hi there Willieulin.
I wonder if the speakerwires are shorting the amp in the JBL stereo!
One or more speakers could be blown......
The protection circuit is most likely doing its job, protecting your stereosystem from damage.
If you have a extra amp connected to the stereo, check if it is wired right.
Try to turn the ignition key "only" so the lights on the stereo turn on. If you turn it further so you start the engine it most likely turns the stereo off.
If that happens the powerwires to the stereo are wrongly connected.
Luck with the problem.
Iceman.

Stereo goes into protect mode

Protect is a safety feature so that you do not blow your speakers. However with it hooked up with the computer you may have surpassed the max output. If it still does this with out going through the computer, it has been damaged.

Do you still have the AVR1500? I have one with a bad tuner--and would be interested in purchasing your for parts. Let me know if you still have it and if you'd be willing to sell it.

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.
