MOS36SUB Mounting Steps

1. Mount temporary holders to ceiling joists.

Cut a couple of 2” x 4”s or 1” x 4”s, a few inches wider than the ceiling joists. Then with a couple of drywall screws, mount the temporary holders to the joists. (Drywall screws not included).

These temporary holders will help you hold up the MOS36SUB and make the speaker mount flush to the future drywall. Using a level, check that your temporary holders are evenly level, adjusting as needed.


2. Adjust the rails, as neccessary, to fit ceiling joists.

Place the MOS36SUB in the desired final location. Then, using a Phillips screwdriver, loosen the screws on each side of the system rails, and extend them so they reach the ceiling joists. Afterwards, make sure to re-tighten screws once the rail length matches the ceiling joists.

NOTE: The cabinet also has screw openings on the short sides so you can move the rails from the long side to the short sides for tight space installations.

3. Securely fix the rail brackets to the joists.

Use a drill and the included screws. Ensure each the screws on each side of the rails are evenly inserted, for a level positioning.

4. Remove the temporary wood supports from the joists.

5. Ensure the face of the speaker is plumb with the joists.

6. Speake wire connection:

To connect the ceiling speaker wire to the Terminal Connector on the Subwoofer module, push down on each connector, and insert each wire into the opening with the correct polarity.

7. Drywalling Steps:

Use the cut-out template to mark the cut-out for the speaker (MOS36MRM) on the drywall/ surface material.

Trace along the inside of the Cut-Out Template, then use a keyhole or drywall saw to cut out the hole.

Place the Placeholder Sponge inside the Port Tube Opening, before installing the drywall, to protect the cut-out hole & port from any debris during the drywalling process.

If using sheetrock that is thicker than ½”, or if the Port Tube cover does not reach the edge of the drywall, attach the appropriate number of spacers according to the depth of the drywall ceiling. The chosen finishing trim kit will be added after the drywall.

Apply drywall/ surface material, plaster & paint, using mesh tape to cover any installation seams. Apply joint compound and level out compound to conceal seams. Make sure to mud up to the rim of the trim ring spacer. Then remove placeholder sponge.

8. Trim Ring Steps:

Once the Placeholder Sponge is removed, the chosen Round or Square Trim Rings can now be inserted into the Subwoofer assembly. Secure the chosen trim ring into all spacers using the 3 included Trim Ring Screws.

9. Adding the Grille Steps:

Lastly, to complete the installation, use the pieces of included adhesive tack, to secure the press grille in place. The grille can be spray painted to better match the ceiling color and environment, prior to being attached.


If you have a problem, try isolating it first. For example, if you’re playing a DVD and there is no sound, try replacing the DVD with an MP3 player to see if you get sound. If it does work, then the problem is with the television, DVD player, or the cables connecting them. If it doesn’t work, the problem will be with the amplifier, speakers, or those cables.

Common Solutions

NO SOUND The volume may be turned down or muted. Check the volume settings volume may be turned down or muted. Check the volume settings on both the amplifier and the DVD player/ television/ computer/ etc.
NO SOUNDMake sure the proper source is selected on the amplifier or receiver.
NO SOUNDCheck the cord connecting the amplifier with the source. The cord may be damaged or plugged into the wrong input or output.
NO SOUNDCheck the wires connecting the amplifier with the speakers. Make sure they’re connected properly and not damaged in any way.
POOR SOUND QUALITYIf you hear something like static, or the sound is cutting in and out, check the audio cables. If the problem increases when a cable is being moved, then the cable is most likely faulty or not connected properly.
POOR SOUND QUALITYToday’s audio systems may have several places to adjust the volume, for example your MP3 player may have a volume control, and your amplifier may also have one. Check to be certain that the volume isn’t turned up past 80% on any device.
POOR SOUND QUALITYTry changing sources to be certain that the selection you’ve chosen is a good quality recording.
