1) Mount so that water will not collect in the enclosure.

2) To optimize output, point the grill end of the enclosure into a

corner.

3) The grill end should have at least 4 inches of clearance between the

grill and the corner it is pointing into.

4) Drill 1/8” (3mm) pilot holes in the mounting surface corresponding

to the 4 mounting ﬂanges of the enclosure. Be sure not to drill into
any critical areas of your boat or vehicle.

5) Install the 4 rubber isolation grommets into the slots on the enclosure’s

mounting ﬂanges. Fasten the subwoofer to the surface securely using
the 4 included tapping screws.

MS-55 Installation Instructions

The MS-55 can be mounted horizontally or vertically on any ﬂat surface.
Since bass radiates uniformly in all directions, the MS-55 can be placed
in out of sight locations such as underneath seats or storage areas.
