You will need to run 4 sets of speaker wires to the trunk to tie into the speaker wires coming off of the stock amps. You will also need to run an antenna extension from the tuner module to the dash. The best way to run the wires is to remove te passangers front seat and pull up the carpeting to access the factory plastic wiring conduit. You will also need to remove the rear seat to get the wiring into the trunk. Here is a diagram of your car.
