DIY Rear Speaker Installation on a 2005 Mustang Convertible

When the Mustang debuted midway through the 1964 model year, a convertible was one of the two body styles available. From 1971 through 1982, there was no convertible option for the Mustang. The drop-top sort of returned in the 1983 model year, but it was a conversion that an outside company performed, not a factory option. In 1994, the convertible returned as a factory-installed option on the Mustang. The 2005 Mustang convertible was only available with the base 4.0-liter V-6 engine and came with a four-speaker sound system. Ford positioned the rear speakers behind the rear quarter panel on the convertible 2005 Mustang, so you must remove the quarter panel trim to get to them.

Step 1

Open the door on the side of the vehicle that you are replacing the speaker on. Pry upward along the door scuff panel, the panel on the bottom of the door opening, using a flat-head screwdriver. Remove the door scuff panel.

Step 2

Pry around the edge of the quarter trim cap, the topmost trim panel on the quarter panel trim, using a flat-head screwdriver to release the retaining tabs. Remove the quarter panel trim cap.

Step 3

Insert your fingers under each side of rear seat cushion and press inward to release the retaining clasps. Lift upward on the front-most edge of the seat cushion and pull it forward to slide the rear of the cushion from under the seat-back cushion.

Step 4

Pry the pin-style retaining clip from the top of the upper quarter panel trim – the trim piece that is right next to the rear passenger when seated – using a flat-head screwdriver. Lift the upper quarter panel trim upward to release its retaining tabs from the slots in the lower quarter panel trim. Remove the upper quarter panel trim from the Mustang.

Step 5

Remove the two pin-style retaining clips from the bottom of the lower quarter panel trim by prying them out with a flat-head screwdriver. Pull the lower quarter panel trim from the vehicle.
