Notice  
Installation of automotive stereo systems requires experience with a vari-  
ety of mechanical and electrical procedures. This manual explains the  
installation flexibility of the Boston Rally Series speaker systems, 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  
Before You Begin  
These are the tools required  
to complete the basic instal-  
lation of the Boston Rally  
Series speakers. Additional  
tools are necessary for more  
custom work.  
Familiarize yourself with the location of fuel lines, hydraulic brake lines  
and electrical wiring. Use extreme caution when cutting or drilling around  
these parts.  
Shut off all stereo and other electrical devices before you start.  
Protect the speakers by keeping them in their plastic bags until final  
installation. Speakers attract metal chips and filings. Always rest the  
speakers with their cones and tweeters facing up.

1. Electric drill with 8" (3mm)  
1
and ⁄4" (6mm) bits  
Never use force when installing any speaker.  
2. Phillips screwdriver  
3. Saber saw, hole saw or  
nibbler  
Check clearances on both sides of a mounting surface before drilling  
any holes or installing any screws. Some screws require over an inch of  
clearance behind the mounting surface.  
4. Utility knife  
Use a utility knife to cut fabric away from hole locations before you  
drill or cut. Fabric is easily snagged by drill bits and hole saws.  
Always wear protective eyewear when cutting and drilling holes or  
when using power tools.  
5. Silicon sealant or weather  
stripping (optional)  
6. Pliers or 7mm wrench (RM9  
only)

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 the wiring.

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. Sometimes the  
stock speaker wires in the vehicle may be used.  
Two-conductor speaker wire connects the positive and negative termi-  
nals of each speaker to the corresponding positive and negative termi-  
nals 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 the  
plain conductor to connect the negative terminals.

thread on one side  
Routing the Wires  
Include a large safety margin when estimating the length of each wire.  
For Doors: Run the wires through factory harnesses or existing holes,  
if possible. If drilling new holes, file the edges and install rubber grom-  
mets and PVC tubing to protect the wires against abrasion.  
For Rear Deck: Run wires along the door sills just inside the car, lifting  
and replacing carpet as required. You may have to remove the rear seat  
to pass wires back to the rear.

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 seal-  
ing 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  
#8 sheet metal screws or other hardware. Tighten the screws just  
enough to seal the woofer against the mounting surface. Do not over-  
tighten the screws.

RM6 Installation Option  
Most factory speaker locations for 6-inch speakers provide either three or  
four screw holes for mounting the speaker. The RM6 includes both sets of  
holes. Rotate the speaker until the correct holes line up.

RM9 Installation Option  
The RM9 can also be installed from underneath the rear deck to reduce  
the installed height of the tweeter module. A spacer is supplied to pro-  
tect the rubber surround and ensure a tight air seal. The spacer is  
installed between the speaker and the mounting surface as shown in the  
diagram.  
The Kortec™ dome tweeter on the RM9 is asymetrically aligned with the  
woofer cone to minimize diffraction of high-frequencies off of the cone.  
Although they are packaged in stereo, matched pairs, either speaker may  
be mounted on either side of the vehicle.

Installing Speakers In Nonstandard LocationsRM6  
Notice  
Check the clearance of both speaker locations. Your vehicle may not be  
symmetrical. (There may be multiple window controls on the drivers 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. If installing in the trunk, check  
for clearance with the trunk lid opened and closed.  
The Boston Rally Series speakers are heavy, and must be held in place  
by a strong, rigid structure.  
Check for signs of excessive water leakage inside the door. If the door  
has a plastic moisture barrier, cut a flap to shield the speakers, or make a  
flap from heavy sheet plastic and attach it to the inside of the door above  
the speaker.

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 seal-  
ing material does not touch any moving part of the speaker.

3. Drill the pilot hole at the center of the cutout, then drill four 8" holes  
for the speaker’s mounting 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.  
5. Attach the wires to the speaker.  
6. Attach the assembly to the cutout as shown in the diagram. Use four  
of the supplied #8 x1" sheet metal screws or other hardware. Tighten the  
screws just enough to seal the woofer against the mounting surface. Do  
not overtighten the screws.  
7. Attach the grille. Snap the grille on to the speaker assembly from the  
front. Be sure to align the logo on the bottom of the grille before attach-  
ing the grille.  
Optional Spacers  
1
To reduce the mounting depth by 2", optional spacers are available that  
can be mounted behind the RM6.

3. Drill four 4" 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. Tighten the nuts  
just enough to seal the woofer against the mounting surface. Do not  
overtighten the hardware.

5. Attach the wires to the speaker.  
6. Attach the grille front. Snap the grille on to the grille frame from the front.  
Be sure to align the notch on the grille with the logo on the grille frame.
