NO NO
A THOUSAND TIMES,
NO.
WHen your run the fader to the rear, you will get no sound. Stop expecting the system to do what it was not designed to do. The crossfire was built with a TWO CHANNEL AM/FM head,
it had no fader. It has a left and right output, PERIOD. The amp in the car has four channels: Left Front, Right Front, Left Rear, Right Rear.
The car came wired like this:
AM/FM head Left output goes to amp's Left Front Input
and Left Rear input.
AM/FM head Right output goes to amp's Right Front Input
and Right Rear Input.
What must be done is four new wires must be ran from your new AM/FM head, these go to the amp. The EXISTING wiring is your FRONT speakers. The added wires are: Two for Left Rear and two for Right Rear.
THEN, at the amp, you connect the four new wires to the Left Rear and Right Rear inputs and cut the jumpers between Left front and Left Rear as well as the jumpers between Right Front and Right Rear. Your fader cant' work until you modify the wiring for true four channel sound.
It's all in this thread here:

Perhaps, but what they do is to tie the left front and left rear together and the right front and right rear together. That kinda works, but yuk.
