Mounting the speakers CAUTION: Be sure to mount your 131 marine speakers on a bulkhead only. We recommend you consult a marine installer before drilling or cutting any holes. Do not mount the speakers on surfaces with concealed hazards, such as electrical conduits or plumbing. TM The cutting and drilling template Locate the cutting and drilling template. It is perforated into the inner carton that contained your grilles and mounting flanges. It helps you position the speaker enclosure by showing how much room to provide for the extension of the enclosure behind the bulkhead. It assists you in cutting the appropriate hole size in the bulkhead wall. See Figures 2 & 3. Figure 3 The template 6 October 30, 2001 AM188201_02_V. pdf Installing Your Speakers From The Rear Of The Bulkhead A Installation from the rear of the bulkhead Choose the 53/8 inch (13. 6 cm) diameter hole size if you can comfortably hold the speaker enclosure from behind the wall while installing screws from the front. If the hole you cut is not perfect, any slight overcut will be hidden by the grille. A 1 Determine that there is enough room by reaching into the mounting area and sweeping with your hand. You should also experiment by placing the speaker enclosure behind the bulkhead before making your final selection. Any orientation of the speaker enclosure is acceptable. CAUTION: Determine whether any obstacles exist behind the mounting surface. Also, be certain that the enclosure will fit within the mounting area before drilling any holes. A2 The round outer edge of the template shows how much room to allow for the grille. The long end is used to plan for room for the enclosure behind the bulkhead. Place the template over the area where the speaker is to be located and mark the 53/8 inch (13. 6 cm) hole with a metal scribing tool or pencil. A3 A4 Drill a starter hole that is large enough for your sabre saw blade. Be sure to drill inside and close to the line you have marked. AM188201_02_V. pdf October 30, 2001 7 Installing Your Speakers From The Rear Of The Bulkhead A5 Using the sabre saw, cut the hole for the speaker, carefully following the line. Take your time; you want a smooth-edged circular hole. A6 Use a half-round file or wood rasp to smooth out any roughness in the hole you have cut. A7 Hold the speaker enclosure up to the hole from behind the bulkhead and find the best position for the extended portion of the enclosure. This helps protect the speaker cone from potential damage during the installation process. Note: For added protection against water entering the bulkhead, you can apply a generic silicone sealant between the flange and the mounting surface. A 16 Replace the enclosure behind the bulk head and place the mounting flange so that it interlocks with the enclosure and lines up with the drilled holes. Next, install six screws through the flange into the matching holes in the enclosure. Note: If you plan to use a screw gun to install the screws, you should first set the gun to its lowest torque setting (do not exceed 12 inchpounds or 135. 84 N-cm of torque). If the screw does not seat properly, finish installing the screw at the next highest torque setting, or by hand. 10 October 30, 2001 AM188201_02_V. pdf Installing Your Speakers From The Front Of The Bulkhead A 17 Remove the speaker cone shield from the enclosure. A 18 Snap the grille in place on the mounting flange. No hardware is needed to secure this part. Enjoy your music system! B B Installation from the front of the bulkhead If you cannot reach the mounting area from behind the bulkhead, you will have to mount the speaker enclosure by inserting it through the front. To do this you will need a 71/8 inch (18 cm) hole, the larger of the two perforated sections on your template. CAUTION: Determine whether any obstacles exist behind the mounting surface. Also, be certain that the enclosure will fit within the mounting area before drilling any holes. B1 Place the template over the area where the speaker is to be located. Snap out the larger one and mark the 71/8 inch (18 cm) hole with a metal scribing tool or pencil. AM188201_02_V. pdf October 30, 2001 11 Installing Your Speakers From The Front Of The Bulkhead B2 Mark six screw holes from the largest hole pattern on the template, but do not drill yet. [. . . ] · Remove the cord from the working speaker and connect it to the "faulty" speaker and either set of receiver connections. ­ If the speaker now works, the problem is in the original speaker cord. · Follow the same procedure for the problem of no sound from one speaker, as outlined above. · Check the connections to make sure they are correctly in phase (+ to + and ­ to ­).
