Turn off the radio before playing with your speakers. You will have to flick the back seats forward , lift up the carpet trim and place forward carefully,remove the trim screws and plugs on each side including the rear trim on the tailgate latch. Carefully pop out the window trims ( It has a few tight spring steel clips, if you haven't pulled car trim before be careful as you may break it ). The speakers are an odd size (5") but they are available in JVC. You will have to refit the speaker wiring with new terminals as they are different. Re-assemble as per dismantle making sure everything is working and the wiring is secured, enjoy.
