On the dreaded JBL Synthesis system, obviously the harness sends line level from the head unit back to the amp module. Do the speaker wires (output of the amp) run all the way back up to the front (dash or kick panel) and *then* out to the individual speaker locations, or do they spider out straight from the amp itself?
I've been looking at the Metra 70-8117 harness, but it sure looks like it uses the factory harness to send signal all the way down to the amp and back. Personally, I'd rather just wire straight into speaker wires behind the dash if possible.
