i took out the stock radio, the stock cd player, the stock amp....disconnect all harness from everything you take out.........go buy a wiring harness for your car.....one of the harnesses will be a grey l shaped one which sonnects to the power harness.....another will be for the speakers which will be a rectangle or square and connect to a plug that you unplugged from the amp....you are not using the amp with aftermarket radios......you can also buy a pocket from crutchfield to fill in the cd player hole

 

I just said forget it and a rewired the whole thing myself. Much easier that way i thought.

 

Mustangs are some of the easiest cars to put radios in. With the proper tools and parts I can be in and out in 10 mins.......................

It is always easier with the hrns.

Check page 2 of my sig and see if the hrns's look the same.

 

why can i not use the stock amp?
and i might just replace it with a new 1.
how many whats is the stock amp?

 

cruchfield has an adaptor that plugs into the amp and a/m radio.

its junk........ You can use it how ever if you ever add a sub then you will know why. That amp will distort and sound like crap long before even the new HU CD player would. Take my work for it you don't want to use it.
