Hey I have a JBL 1200 and when I installed it a red light came on instead of a green one. The manual says it is because of excess voltage B+ and to check for a faulty voltage regulator. Well is this the reason or not because I asked a few people and they said it could be several things i.e. speaker wires, RCA's, etc. But I disconnected everything except the power wires and it still did it. Any help?
blah blah blah blah.
I love the way JBL is attempting to play mechanic by blaming a voltage regulator for a poorly designed amp.
Likely the regulator is not the cause, as you would notice other things within your car not acting properly first.
A voltage regulator's job is to measure and meter the ammount of voltage that can safely pass from the alternator into the cars electronics.
Get ahold of a DVM - set it to 12 VDC, and take a voltage test at the battery and at the + terminal of the amplifier. - to ground and + to + in both cases.
Your reading should be almost the same at both test points, and if it is between 13.5 -14.7 volts at idle- everything is working correctly.
Assuming that your ground, remote, speaker, and RCA wires are all correct.
Amplifier is faulty if your charging system passes this test.
take it easy,
