You have a ground loop if its only happening at night. Normally the shound is caused by a bad install. Running the rcas with the power wire and that kind of stuff.onenighter712 said:that noise coming from your speakers? . . . I get the same problem in the nights when I turn on my lights on along with the system. . . i heard it's noise coming from the alternator and going through the wires and into the speakers. .. well I still need to find out how to fix the problem . .
I have an OPTIMA YELLOW TOP, a TSUNAMI 2-FARAD BASS CAPACITOR, a 150 amp alternator. . . so WHAT'S THE PROBLEM!?!?!?
