I have a Jbl 1200.1 and when i turned it on the 1st time everything was fine. Then i looked at it later that day when it was playing and the red lite was on. (no subs hooked up) In my manual it say there is excessive voltage on B (+) connection. Then it says to fix it I have to check my vehicle for defective voltage regulator. Problem is if I need a refund I have to know now or else I cant send it back, but I would much rather repair it. Please help, THANKS. :mad:

hook up some subs then est it out and if the problem is still there then i would check the voltage regualtor. Also once the subs are hooked up see if the light changes from red to green if the amp is given more power (reving engine or driving above 2500rpm)
