Panel Removal: Before the
subwoofer enclosure can be installed, removal of the factory side panel is
required. This requires a Phillips-head screwdriver to remove the upper trim
panel, and a #50 Torx bit to remove the upper and lower seat belt bolts.
Bracket Installation: In order
to install the mounting bracket, you will need a 10mm socket or wrench. The
amplifier on Bose-equipped vehicles is mounted in the same location. The bracket
will install over the amplifier using the same bolts that secure the amplifier.
Lower Trim Panel: In order for
the mounting studs to pass through the lower trim panel, holes will need to be
drilled in the storage pocket area. A drill and 3/8" drill bit will be needed.
Woofer Installation: Because
the enclosure is secured to the mounting location from the inside of the
enclosure, it is necessary to fully install the enclosure in the vehicle before
mounting the woofer in the enclosure.
