Mounting Considerations
When mounting the subwoofer in an area exposed to weather or water, you must mount the subwoofer on a vertical surface. If you mount the subwoofer on a horizontal surface facing up, water can gather in and around the subwoofer, causing damage over time.
If you intend to mount the subwoofer outside the boat, you must mount it in a location well above the waterline, where it is not submerged or damaged by docks, pilings, or other pieces of equipment. When mounted correctly, this subwoofer is rated for protection from the front of the speaker. Water exposure and damage to the rear of the subwoofer voids the warranty. This includes situations when the subwoofer is mounted in a sealed enclosure, especially if it is exposed to wash down. Using an enclosure with a port or vent exposed to the outside environment may allow water to collect and damage the subwoofer.
You must turn off the audio system before making any connections to the source unit, amplifier, or speakers. Failure to do so could result in permanent damage to the audio system.
You should protect all terminals and connections from grounding and from each other. Failure to do so could result in permanent damage to the audio system and void the product warranty.
When selecting a mounting location for the subwoofer, observe these considerations:
-
You must select mounting locations that provide sufficient clearance for the mounting depth of the subwoofer as specified in the product specifications.
-
You should select a flat mounting surface for the best seal.
-
You should select a location where the surface material is thick enough to support the weight of the subwoofer. It's important to note that when in use, the subwoofer exerts a pushing and pulling effect on the surface, so if the material is thin, it can result in excess vibration and negatively affect the sound quality.
-
You should protect the speaker wires from sharp objects and always use rubber grommets when wiring through panels.
-
To avoid interference with a magnetic compass, you should not mount the subwoofer closer to a compass than the compass-safe distance value listed in the product specifications.
Selecting the correct mounting location optimizes the performance of the subwoofer. Fusion® speakers are designed to perform in the widest possible range of mounting locations, but the more you plan the installation, the better the speakers' sound will be.
