5 front left channel doesn't work
The low ohm light is on when the unit is turned on. even with no speakers and input signal connected. the unit has been working fine for 4 years of very light use. but now its gone "bad" the system does put out sound but it is distorted and it only comes out of one of the front speakers. I am driving 2 JL speakers with the front channels, and a JL 10" subwoofer. Any help is welcome.

The first thing is to meter all the speakers with a volt/ohm meter. They should read somewhere between 2-6 ohms. If they meter good try swapping the RCA's and see if there is any difference. But if both of those check out ok than. Unfortunately it would appear that your amp has a bad output channel. What seems to happen is that when the amp is cycled off and on, off and on etc. the solder on the PCB can get brittle causing problems. The only answer i can offer is to send it to JL to repair or find a good repair shop that works on car audio amps. It's getting harder to find a good tech but they are out there. If you send it to JL they have a set repair rate of $180.00 which covers the return postage while the customer pays the shipping cost getting it there. They do an excellent job and pretty much go thru the whole board and replace not only what is wrong but will also perform any mods or changes since date of manufacture.
