looking at the above diagram for a amp would i use the amp trigger wire or the accessory switched wire to turn the amp on?
Mitch, technically you could connect your 2008 Ford Focus amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever your 2008 Ford Focus is on and off whenever your 2008 Ford Focus is off. Just make sure to run an in-line fuse holder
with a 1-amp fuse
on the amplifier turn on wire. Hope this helps. Good Luck.
I’m having a heck of a time installing a new radio in my 2008 Focus SE!!! Seems my problem is the two sets of factory wires that are gray/orange and violet/orange. I’m stuck here. Can anyone help me out?
