Crutchfield Customer Review (What's this?)
I replaced all four given that the fronts were blown and one of the rears was dead (I blame it on the frat brothers using the truck at some festival but I really think it was me after night out). Obviously the improvement in sound quality was noticeable ... The 6.5 " fits nicely. The provided mount brackets came in handy for the front. Simply remove the side mounts, I used a small hacksaw.. All I needed was the 2 bottom hangers and the top clip. Mount the speaker to the bracket, attach the provided wiring harness to the speaker and you are ready to install. I did not need any bracket for the rear. I found I was able to remove the 3 bolts that attach the OEM mount and speaker to the door (you need to make some minor cuts in the plastic cover to access the bolts. Once out of the door, remove the 4 screws that attach the speaker to the OEM bracket and gently pry the OEM speaker from the OEM mount. Its attached with a sealant so you need to slowly walk the old speaker off with a putty knife. It comes off clean. It is the a simple process to attach the new speaker to the OEM bracket using the 4 screws as the holes lined up nicely. Attach the wiring harness provided and you are ready to mount into the door. Note: If you have a second pair of hands to hold the door panels, you dont have to remove any of the wiring connectors. I found that once you have the panels slid in place, start your attachment with screw that holds the door handle.
Pros: Fairly easy installation with minor modifications to the bracket. If you are a DIY'er its a breeze I should have done this years ago
