Have a jl audio 500/1 the red light blinks and no other light turns on. whats the problem with it?
I think you might have your remote turn on from your deck to amp hooked up wrong check that out!! I not are you familliar with the mr. butterworth crossover JL developed for that series of amp? Just like its big nrother the 1000x1 class D the built in smart crossover has many built in pretect modes. If your subs are drawing to much power it shuts down if they draw to little of ohms or to many but that 500 is 1 ohm stable so download the crossover settings from JL and go from there

I have a jl 500/1 amp hooked up in my car and the power light comes on for about 5 seconds then turns off. no sound out of the subs. it is hooked up to a factory deck through a high to low level converter....
hook up the remote wire ( or make sure its hooked up good) check your ground! ground wire not big enough awg wire and put on bare metal not more than 1 foot away from amp. bad ground will cause this.

I have a jl 500/1 . The distribution block is lit showing 12v plus. no green power light on the amp? I disconnected pwr and ground and reconnected. the green light came on for 10 seconds and shut off. all...
The amplifier will not power on unless/until it recieves the turn-on signal from the head unit.

It seems the issue is with the head unit in this case.

Check the fuses and verify constant and switched power with a multimeter.

Once the Head unit powers on - the amplifier should also.

Green power light on JL Audio 500/1 but no output
Its the power transistors that would be affected by low voltage. It delivered till it finally gave up 'cos the output wattage to be generated at low voltage means more current flowing through the equipment. This high current will adversely affect all small solenoid valves & transistors and IC's. Even failure of one section of any IC is rarely detectable with the naked eye. It has to be thoroughly checked with a multi-meter to assess the damage correctly......sodeep

Jl audio 500/1 amp low ohm light at high volume
I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.

It is going into protect mode for a reason.
Disconnect the subs and turn everything on again. If the light comes on, the problem is internal and will need servicing by a technician.

500/1- Low ohm light
Disconnect the speaker wires from the amplifier's terminal block. If the low ohm light still comes on with no speaker wires connected, the amplifier will need to be repaired.

If the light no longer comes on, check the speakers and the wiring.

Jl audio 500-5
Assuming that you've confirmed that the speaker is in good working order and that the wiring isn't shorted in any way...

There are separate power supplies for the high and low amplifiers. It's possible that the one for the sub output has failed. If that's the case, the output transistors probably failed and that's what damaged the supply.

Generally, I'm willing to help people repair their amps but this is a large, complex amplifier and it should be repaired by a qualified technician.
