Hi guys, I just put a new headunit in my little brothers 05 mustang gt it has the shaker 500 system. I used the appropriate harness (705521) and now I am getting a poping sound when the ignition is being turned on. I suspect it is the amp remote turn on is to high of voltage, like in the previous body style mach systems you had to use a resistor to reduce the aftermarket headunits 12v remote turn on to a 5v. Does any one have any input on this before I go foreward?
Thanks,
Chance
