Hey guys,
I bought a F700bt a few weeks ago. It has been a great deck. I just bought a used F900bt for another vehicle I have and i'm having issues with it. The subs worked fine with my F700bt. No when I hook the 900 into my truck the subs start pounding the minute I put power to the head unit. I have both decks working fine just having issues with the subs going off for no reason on the 900. What could be my issue? I'm guessing it is more of a hardware then a software issue. I have turned the sub function off on the 900 and it still keeps pounding. Any suggestions?
