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.

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.
