Planning the Installation Read all instructions carefully before you attempt any installation procedures. Make sure all operations are clear to you. Make sure you have adequate time and shelter to complete the installation. Many installations require multiple days to complete. Examine the Boston Rally Series speakers and hardware so that you are familiar with them before you start the installation. 1. Decide on speaker placement. 2. Run the speaker wires. 3. Install the speakers and complete th

Speaker Wiring For your convenience, two sets of two-conductor wire are provided to use between the speakers and the amplifier or head-unit. Other wire may be substituted if desired as long as it is at least 18 gauge. Two-conductor speaker wire connects the positive and negative ter- minals of each speaker to the corresponding positive and negative ter- minals on the amp or head-unit. One side of the wire will be marked in some way. Use the marked conductor to connect the positive terminals and

Installing Speakers in Factory Cutouts 1. Make sure the mounting surface provides a complete air seal between the front and the back of the speaker. If the surface is uneven, or if air can leak directly from the back of the speaker to the front, seal the air leaks with silicon sealant or weather stripping. Make sure that the sealing material does not touch any moving part of the speaker. 2. Attach the wires to the speaker. 3. Attach the assembly to the factory cutout using four of the supplied #

RX47 Notice The RX47 is supplied with the grille adapter ring attached to the metal basket of the speaker. For many factory cutouts, this adapter ring will have to be removed for installation. 1. Hold the speaker between both of your palms with the speaker cone facing you. Hook your fingers behind the magnet assembly. 2. Push one locking tab out and back with your thumbs to release it from the speaker frame (see diagram). Repeat this on all sides of the adapter until the adapter falls free. RX

RX87 and RX97 Installation Option The RX87 and RX97 can also be installed from underneath the rear deck to reduce the installed height of the tweeter module. A spacer is sup- plied with these speakers to protect the rubber surround. The spacer is installed between the speaker and the mounting surface as shown in the diagram. 7

Installing Speakers In Nonstandard Locations Check the clearance of both speaker locations. Your vehicle may not be symmetrical. (There may be multiple window controls on the driver’s side, for example.) If installing in the doors, remove the interior panel. Avoid possible speaker contact with door frames, handles and window tracks. Check the window clearance by rolling the window up and down. Also check for clearance with the door open and closed. The Boston Rally Series speakers are heavy, and

1. Trace the template onto the mounting panel. Mark the pilot hole, the edges of the large cutout and the locations of the screws. 2. Make sure that the mounting surface provides a complete air seal between the front and the back of the speaker. If the surface is uneven, or if air can leak directly from the back of the speaker to the front, seal the air leaks with silicon sealant or weather stripping. Make sure that the sealing material does not touch any moving part of the speaker. 9

Make the large circular cutout with a saber saw, hole saw or nibbler (depending on the material). 4. Slip “U”-clips over the screw holes. Position the flat side toward the speaker as shown in the diagram. 5. Attach the wires to the speaker. 6. Attach the assembly to the cutout as shown in the diagram.

Attach the assembly to the cutout as shown in the diagram. Use the supplied machine screws and nuts or other hardware. Tighten the nuts just enough to seal the woofer against the mounting surface. Do not over- tighten the hardware. 5. Attach the wires to the speaker. 6. Attach the grille front. Snap the grille on to the grille frame f

Professional Tips • Some installers construct mounting surfaces from MDF. This dense material dampens resonances and provides a rigid mounting surface. • In cases where the speaker is being mounted on the surface of the interior door panel and there is a gap between the panel and the metal of the door, an appropriate thickness of MDF can be used as a spacer. • When mounting the speakers in nonstandard locations in the front of the car, try mounting them as high up and forward in the doors as

Adding Subwoofers and Electronic Crossovers The best way to combine a subwoofer with your Boston Rally Series speaker system is with an electronic crossover. Level matching (making the subwoofer play at the same level as the coaxial system) and precise frequency division are much easier to get right with an electronic crossover. Additionally, electronic crossovers have no insertion loss, and they isolate the coaxial speakers from the subwoofer’s back EMF. Subwoofer Crossover Frequency Recommenda
