Boston Rally Series coaxial speakers, not the exact installation methods to be used in any given case. If you do not have the experience that these procedures require, we strongly suggest you consult your Boston Acoustics dealer about professional installation.
Tools Required These are the tools required to complete the basic installa- tion of the Boston Rally Series components. Additional tools are necessary for more cus- tom work. 1. Electric drill with ” (3mm) ” (6mm) bits 2. Phillips screwdriver 3.
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.
stripe on one side ridge on one side 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.
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.

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.

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.
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.

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.
RX47/RX57/RX67 3. Drill the pilot hole at the center of the cutout, then drill four screws. 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.
RX87/RX97 3. Drill four ” holes for the speaker’s mounting screws. Make the large elliptical cutout with a saber saw or nibbler (depending on the material). 4. Attach the assembly to the cutout as shown in the diagram. Use the supplied machine screws and nuts or other hardware.
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.
Only through experimentation can the optimum crossover fre- quency be determined. However, you can use the following guide as a starting point. Start with a crossover frequency of 100Hz for the RX47 , 90Hz for the RX57/RX57 , 80Hz for the RX67/RX67 70Hz for the RX97.
