SKU#90136/90137
We strongly recommend that you have your new Enclosed 3-Way Weatherproof Subwoofer/Satellite system installed
by your authorized JL Audio dealer. The installation professionals employed by your dealer have the necessary tools
and experience to mount the enclosure properly. If you choose to attempt the installation yourself, please read this
installation guide completely before beginning the process.
If you choose to per form the installation yoursel f, it is absolutely vital that the
enclosure be prop erly mounted according to these instruc tions. Failure to
mount the enclosure properly presents two problems:
1) The sub-bass per formance will suffer due to the movement of the enclosure
caused by the force exe rted by the woofer(s).
2) A loose enclosure pres ents a serious safety haza rd in the event of a collision
or other such accident.
STEP 1
Determine the desired location for the Enclosed Subwo ofer/
Satellite then decicide on which sur face would be the
best location for the universal mounting bracket. It can
be installed on any side of the enclosure to fit a variety of
applications. Here the br acket is shown on the top.
