Question about Jl Audio E2150 Car Audio Amplifier
My amp has power. the green power light is on, but there is no sound coming out of the speakers. the speakers are good. i hooked them up to the amp in my truck and they work great. i checked the outputs with a voltemeter with the stereo on, and i didn't get a reading. can anybody help?
I often troubleshoot these issues via a stereo head set, modify the leads so you can "Touch" them onto the Speakers Output Terminals, connect the "Shields" together, thats "Earth" and the other Two, are Left & Right... with the Amp's volume turned to about 25% volume, connect up the Earth wires to the Chassis with a clip, under a srew etc, just make good contact... then touch the Left & right wires onto the output, ya should hear sound... if not most probably the Output device(s) may have gone faulty.

Sony generally drives their power light from a source that does not rely on the amplifier's switching power supply. This means that it's not a good indicator as to the health of the amplifier.
As long as you have B+ and remote voltage, it will light up. Since you've tested the speaker and the signal source, I think the amplifier is likely defective.
