first of all i searched but couldn't fine any thing on it. my question is how do i hook the speaker wires on the new head unit to the car. because i want to keep the factory Bose amp(its a pain and don't have much money to spend) so to the harness do i hook the new HU's speaker wires or do i have to take a RCA cable and cut out one end and hook it up. But there like 8 speaker wires comming out of the BOSE hu and theres only left and right on the pre amp out
