My model didnt come with rear speakers and I decided to add some cheapo ones. Picked up a pair of boss 6.5" on amazon for $12.88 and had some fun. The rear does have the wires installed but they are taped to the door. Door panel is held on by 3 screws on the exterior and 2 on the underside of the power window switch panel, remove door panel and lock mechanism(cables). I decided to do a little cutting to get them to fit, I used an angle grinder and fire extinguisher (risky sparks), then I filed the edges, taped remainded of plastic sheet and hit it with some plasti dip to prevent rust and maybe improve audio resonance. Saudered and heatshrink on all the connections, overall very happy for $12.88 LOL. Next for the front
