Speaker placement and positioning | 131™ Marine Speaker System

Placement locations depend on the mounting surface.

There are two possible mounting options. It is easiest to mount the speakers from behind the mounting surface (Figure A). However, if you cannot reach behind the mounting surface, you may cut a larger hole that allows you to insert the speaker enclosure from the front of the mounting surface (Figure B). With this in mind, find a location that:

  • Allows sufficient room to snap on the grille. Use the template to be sure there is enough area around the holes you will cut in the bulkhead.
  • Allows sufficient room for the speaker enclosure behind the bulkhead. During installation, the enclosure requires 1⁄2 inches (11 cm) of mounting depth. However, once installed the enclosure requires only 3 1⁄2 inches (9 cm) of mounting depth and 12 inches (31 cm) of extension. The enclosure may be rotated in a complete circle but attaches to the mounting flange in only one position.
  • Accommodates the speaker wire provided. Lay out lengths of wire that comfortably reach from the receiver to each speaker. Be sure the wires are secure and protected from being pinched, pulled, or damaged in any way.
  • Is not closer than 3 feet from the compass.
