BMW Z3 Model 68 Subwoofer Installation Instructions
Read these instructions from start to finish twice before you even go near the car! Professional installation is recommended for those who are unfamiliar with car audio. These instructions assume you have already installed your new amplifier.
Remove the old enclosure1. Carefully remove the subwoofer enclosure cover by first lifting the rear edge of the cover and then lifting entire cover straight up. The cover should lift out with minimal effort, but may require some additional effort to release the rear snaps. Take your time and be careful when removing the sub lid! The easiest thing to do is to insert a flat, metal, handled-tool like a stiff putty knife and carefully pry each side up from the back. NOTE: If you have the storage compartment, you may find it easier to temporarily remove the storage compartment lid while performing the install.
2. Remove the 4 mounting screws (2) from the existing speaker enclosure (1). If you have the storage compartment, remove the screws holding the compartment liner and lift out the liner.
3. Remove the old enclosure (1) by pulling upwards. Disconnect the wiring harness connector (2) and remove the entire enclosure from vehicle.
4. Using a knife, diagonal flush cutters or small saw, carefully trim away the 4 plastic extrusions (2). If you have the storage compartment, remove the (4) center extrusions—Do Not remove the extrusions the storage compartment lid hinges mount to.
5. Remove the old foam insulation from the rear panel of the sub compartment. Remove the backing from the sound matting and apply in the upper center portion of the rear plastic panel. Press matting firmly against panel to ensure complete adhesion.
Prepare the Subwoofer Compartment
Overview: The Model 68 enclosure is designed with the speaker facing toward to the rear of the vehicle. The “L” shape in the back/bottom of the enclosure faces the front of the vehicle, and rests over the beam that runs sideways through the enclosure compartment. The protrusions on the speaker side of the enclosure are standoffs to ensure proper clearance between the speaker and the plastic panel at the rear of the subwoofer compartment. The round hole drilled from top to bottom in the back of the enclosure (the part towards the front of the vehicle) accommodates the mounting bolt. The wire terminal cup mounts in the rectangular hole in the driver’s side of the enclosure.
