Hello everyone:
I just bought a new stereo/CD head unit for my Westy.
The new unit has the following wires for the speaker system:

A +, front right
B -, front right

C +, f left
D -, f left

E +, Rear, right
F -, Rear, right

G + Rear, Left
H � Rear, Left

Now, the factory harness that runs through the vehicle to the rear speakers
has only THREE wires (  + Rear, right,  + rear,left and a common (grey)
ground).
The front speakers have independent + an � for each speaker.

My question:
Does anyone have experience with connecting a modern stereo to the rear?
Specifically, can I connect my wires F and H to the grey ground wire for
both of the rear speakers?
Would this cause any problems?
(I really don�t want to have to run another wire all the way back and up�.)

Thanks

Rio
