* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1W/1m) is not an accurate indicator of a subwoofer’s output capability and should not be used
as a comparison to other subwoofers to determine which one is “louder” !
We recommend the use of this speaker in a bi-amplified system using high-quality satellite speakers and amplifiers.
We do not recommend the use of this subwoofer with a passive crossover (coil), as this type of device will adversely
affect performance.

INSTALLATION PROCEDURE
The diagram above shows the typical
installation procedure into a fiberglass panel using
the supplied hardware (Classic Grille Model shown.
Installation is the same for Sport Grille Models).
Always follow proper safety procedures when
working on a vessel. Use eye-protection at all times
and a dust mask and gloves when cutting.
1) Choose a flat mounting surface that has
sufficient
depth and air space behind it to accept
the subwoofer.
2) Cut a 8.875-inch (225 mm) diameter hole.
3) Run the speaker cable to the mounting location.
4) Place the woofer in the hole and mark the screw
hole locations using a sharp, pointed tool.
5) Remove the woofer and drill a pilot hole
(see chart on next page) in each of the screw
locations. It is also advisable to use a hand-driven
countersink tool on each hole to further inhibit
gel-coat cracking of fiberglass panels.
6) Connect the speaker wires and place the woofer,
with its grille in place, into the opening (for Sport
Grille models, pay attention to where the logo
badge will added.
7) While holding the speaker firmly in its mounting
location, evenly snug the mounting screws in a
criss-cross pattern, then hand tighten in a criss-
cross pattern.
Non-standard installations may require different
hardware. Always use marine-grade, stainless-steel
fasteners to ensure a secure, reliable installation.
