Mach 460 New Head Unit

[Paul1981610]

Replaced the old 6 disc head unit for an aftermarket. Used all the proper harnesses but the rear subs aren't working. The door subs are. Now the one thing I don't know is if they were working before. Are there any issues that make the rear not work after a swap or could an amp be bad

Probably a bad amp. I did the same thing but after a while the subs went kaput. Were they working with the old head unit?

No

I just went through the same thing in my 04 GT. This is what you will need for the aftermarket radio install:

If the amps are bad, that is easy enough to change.
