I'm going to be cutting out my own holes on the panels for the speakers in the rear, any tips? And was wondering where would I connect the rear wires to? I have a after market hu a Pioneer p4900ib to be exact, with a dci thanks.

 

bump for help, searched.

 

Mount your speakers in the panels. Then run speaker wire for each speaker from your HU to the speakers.

Voila, done.

 

yeah but lets say there's 4 wires, left rear positive/negative and right rear positive/negative, would I splice into the harness to those outputs or would I utilize rca jacks?

 

The + and - speaker leads are right on the back of the HU. Run these to the back of the speakers.
