On my 17TRDSport 4 door speaker upgrade, here's what I discovered today. Hope this is helpful.
The front door speakers were not difficult to install but time consuming. It was not necessary to remove the green and white metal balls from the door handle. I just slipped the silver handle through the interior door slot. That saved me from trying to remember where the green and silver balls attach.
I covered as much of the metal door with the sound deadening material as I could reach. I concentrated on the metal in back of the openings of the metal interior part of the door. I also added material around the edge of the plastic grill. Plastic interior, of course.
I did not throw out the plastic that covers the door. Rather, I pulled it away so I could reach through the openings. Then I replaced it against the black sticky stuff, and then put deadening over the openings that the fiber material covers.
The biggest challenges??? The frame to hold the speakers is a pain to position and screw in. I had to make a new hole in the frame. Careful not to puncture the speaker.
The wires slide into metal connector at the speaker end nicely. The biggest problem was that the wire to use for the replacement speakers had just 2 bear wires at the other end. My solution was to push the wires into the original white plastic harness, tape it up, and now it works just fine.
I was concerned about polarity, but there was nothing in the instructions or on the speaker clips to help me figure this out. So, I took a chance. For the front door, the negative wire from the speakers inserts into the harness opening that is next to the smooth edge of the harness. Sound is good.
Took lots longer than I expected. Best not to rush.
Next, the rear doors.
