Question about Jl Audio 300/4 Car Audio Amplifier
You should have blown a fuse. Check the main power fuse feeding the system (usually at the battery). If it appears to be good, you'll need a multimeter to check the voltage at the B+ and remote terminals of the amplifiers. Place the black meter lead on the ground terminal of the amp when testing. .
