Select the locations for your speakers In selecting locations for your speakers, understand that there are two possible mounting options. It is easiest to mount the speakers from behind the mounting surface. 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.
Mounting the speakers CAUTION: Be sure to mount your 131 holes in the hull. We recommend you consult a marine installer before drilling or cutting any holes. Choose a safe spot for drilling. Do not mount the speakers on surfaces with concealed hazards, such as electrical conduits or plumbing.
Installation from the rear of the bulkhead Choose the 5 speaker enclosure from behind the wall while installing screws from the front. This is the preferred mounting method. If the hole you cut is not perfect, any slight overcut will be hidden by the grille. Determine that there is enough room by reaching into the mounting area and sweeping with your hand.
