Question about Jl Audio Car Audio & Video
I need a schematic for a JL audio 500/5. Left front output has static. Not sure if it's a transistor or resistor. Even with no input source (on bench). Can't find a schematic anywhere!
SOURCE: Audio Amplifier JVC Model A-GX3
If the service manual is not available on the JVC websites then you should just Google search "JVC A-GX3 service manual" There are many websites that archive manuals. You'll probably have to pay for a copy. Why can't you disassemble the unit and see the output transistor numbers first? More importantly how do you know this is the fault?

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.
