I Just ordered Rockford Fosgate 6.5 for the front and rear hatch. Now i have tried to wire this before but became confused. I do have a monsoon package with a aftermarket head unit. There are 4 wires that connect to one speaker do i have to wire just the regular 2 wires for the speaker to work or wire all 4 wires? please help

 

The front doors have 2 seperate speakers, the full range 6.5s and the tweeters. Use the wires that go to the 6.5s, the tweeters are on a crossover built into the amp. Also the rear seat area is set up for subs and if you want to run full range there you need to rewire the amp outputs from the rear hatch area to the rear seat area. Google search the Monsoon Wiring Schematic and you can see what needs to be done. I did it in about 1/2 hour.
