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 . See Figure 2 . 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 41 / 2inches ( 11 cm ) of mounting depth . However , once installed the enclosure requires only 31 / 2inches ( 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 close enough to adversely affect any compass . Note : The magnets in the speakers will affect a boat compass . Avoid mounting the speakers closer than three feet from the compaSSr If necessary a marine installer can help correct any deviatiOnr F _ umZ Selecting the right locations A . Mount from the rear ifyou can insert the speaker enclo - sure behind the bulkhead mounting surface B . Mount from the front if you cannot reach behind the mounting surface If you are uncertain about the depth and clearance behind your mount - ing surface , consult your boat manufacturer or dealer I . _ _ Note : Before going any further with your assembly , choose one of the methods de - scribed in Figure 2 above , The instructions for A begin on page 7 ; B on page 11 .

Test the speakers It is a good idea to test your system before installation . With the power turned off , connect the receiver to the speakers . The provided speaker cord consists of two insulated wires ; one is marked or ribbed , and is always positive ( + ) . The plain wire is always negative ( - ) . The wires correspond to the red ( + ) and black ( - ) terminals on the back of the speaker , receiver , or amplifier . Place the stripped end of the positive ( + ) right channel receiver wire together with the stripped end of the positive ( + ) right speaker wire . Then place the stripped end of the negative right channel receiver wire together with the stripped end of the negative right speaker wire . Repeat this procedure for the left speaker . Be sure to connect each wire to the proper terminal ( positive to positive , negative to nega - tive ) . For this test , just twist the wire ends together . You will use the supplied wire nuts for the permanent connections . When you are satisfied that everything works , disconnect the speakers and continue with the installation . Mounting the speakers CAUTION : Be sure to mount your 737 ' _ marine speakers on a bulkhead only Do not cut 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 . 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 . The template has four functions . 1 . It helps you position the speaker enclosure by showing how much room to provide for the extension of the enclosure behind the bulkhead . 2 . It shows you how much room to allow for the snap on grille . 3 . It assists you in cutting the appropriate hole size in the bulkhead wall . 4 . It helps you drill the mounting screw holes in the bulkhead . The template has two punch - out hole diameters . Use the smaller size for installation from behind the bulkhead . Use the larger for installation from the front . See Figures 2 & 3 . Figure 3 Thetemplate 6 October 30 , 2001 AM188201 _ 02 _ dpdf

Installation from the rear of the bulkhead 0 Choose the 53 / 8inch ( 13.6 cm ) diameter hole size if you can comfortably hold the 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 . Determine where you will drill the hole for the speaker . 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 surfaCer Tobe certain , contact your boat manufacturer or deale _ Also , be certain that the enclosure will fit within the mount - ing area before drilling any holes . 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 . There are two perforated circles in the template . Snap out the smaller one . Place the template over the area where the speaker is to be located and mark the 53 / 8inch ( 13.6 cm ) hole with a metal scribing tool or pencil . 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 . AM 188201 _ 02 V . pdf October 30 , 2001 7

Using the sabre saw , cut the hole for the speaker , carefully following the line . Take your time ; you want a smooth - edged circular hole . Use a half - round file or wood rasp to smooth out any roughness in the hole you have cut . Hold the speaker enclosure up to the hole from behind the bulkhead and find the best position for the extended portion of the enclosure . Be sure the enclosure is hidden behind the bulkhead . If the enclosure does not fit , use the file or rasp to enlarge the hole . Place the mounting flange so that it interlocks with the enclosure and is flush with the mounting surface . 8 October 30 , 2001 AM188201 _ 02 _ _ pdf

Marksixscrewholes . Usethesmallest holepatternthatfits . Removteheenclosurferombehindthe bulkhead . CAUTION : Be sure the enclosure is not in _ lace behind the bulkhead while drilling . Drill the marked holes using a 1 / 8inch ( . 32 cm ) bit . Use a center punch to make a slight indentation for your drill bit . This will keep the drill bit from " walking " away from the mark you have made . You need to open one of the five marked drain holes because water can enter your 131 " ' marine speaker through the ports on the front of the enclosure . Holding the enclosure in the mounting position you chose in Step 7 , find the drain hole that will be at the lowest point when the speaker is mounted and break through the surface using a center punch , awl , or 1 / 8 inch ( . 32 cm ) drill bit .

Connect the speakers . Be sure the receiver or amplifier is turned OFE If possible , disconnect the power source . Use the supplied silicone - filled wire nuts to secure the ends of each wire pair . Place the stripped end of the positive ( + ) right channel receiver wire together with the stripped end of the positive ( + ) right speaker wire . Place the wire nut over the ends of the wires and turn it in a clockwise direction . Turn it with firm pressure until it stops ; there should be no uninsulated wire visible . Repeat this procedure for the remaining wire end . Repeat the above procedure for the left speaker . Check that all connections are made positive to positive ( + to + ) and negative to negative ( - to - ) . Tighten any loose connections before you plug in the receiver or amplifier and turn it on . Note : Twisting the ends of the wires together is not necessary Tie a knot in each joined wire pair to protect the connection from being pulled apart . Remove the perforated speaker cone shields from the enclosure cartons . Insert the tabs of the shields into the speaker ports . 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 . 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 . Attach the flange to the mounting surface using six screws . Next , install six screws through the flange into the matching holes in the enclosure . Note : Ifyou 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 inch - pounds or 135r84 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 _ I / pdf

Remove the speaker cone shield from the enclosure . Snap the grille in place on the mounting flange . No hardware is needed to secure this part . You are now finished with the assembly . Enjoy your music system ! Installation from the front of the bulkhead 0 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 / 8inch ( 18 cm ) hole , the larger of the two perforated sections on your template . CAUTION : Determine whether any obstacles exist behind the mounting surface . To be certain , contact your boat manufacturer or deale _ Also , be certain that the enclosure will fit within the mounting area before drilling any holeSr Place the template over the area where the speaker is to be located . The round outer edge shows how much room to allow for the grille . The long end is used to judge the room needed behind the bulkhead . There are two perforated circles in the template . Snap out the larger one and mark the 71 / 8inch ( 18 cm ) hole with a metal scribing tool or pencil . AM188201 _ 02 Epdf October 30 , 2001 11

Mark six screw holes from the largest hole pattern on ® the template , but do not drill yet . You may need to mark and drill a different set of holes along the same circle before finally attaching the flange . Note : These markings are important to help keep the saw blade inside the Iine you have just drawn . 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 . Using the sabre saw , cut the hole for the speaker , carefully staying just inside the line . Take your time ; you want a smooth edged circular hole . CAUTION : Be sure to stay inside the line you have marked , and in particular , be sure to stay well inside the hole pattern you have marked . The marked holes , or others along the same circle , will be used to secure the speaker and must not be too close to the speaker hole , It is also important to stay inside the fine because any error you make could be visible after the speaker grille is installed , Use a half - round file or wood rasp to smooth out any roughness in the speaker hole you have cut . 12 October 30 , 2001 AM188201 _ 02 _ dpdf
