Installing the Components
The Polk/MOMO System Crossovers
You will need to make wiring connections from your amp or radio to the crossovers and
from the crossovers to your mid/woofers and tweeters. Choose crossover box locations that
are convenient for making these connections. As there are adjustments on and in the
crossover networks which you will need to access during the “fine tuning” stage of the
installation, place them in a spot that’s easy to get to. Once you’re done fine-tuning
the system, the crossovers can be hidden away and secured. Do not install into
doors due to potential water damage. This is not covered under
Manufacturer’s Warranty.
Your Polk/MOMO Series crossovers have clearly marked terminals. The wires provided with
your Polk/MOMO System have one red as the positive (+) lead and one black as the negative (–) lead. Connect the red to the positive (+) terminals on your crossovers as well as to
the positive (+) terminals of each speaker. Connect the black to the negative (–)
terminals on your crossovers as well as to the negative (–) terminals of each speaker.

Installing the Polk/MOMO System Mid/Woofers in Factory Locations
Most cars have speaker grilles that blend with the rest of the car’s interior. Sometimes it is
difficult to determine how to remove these grilles to gain access to the speaker that you
intend to replace. If you have one of these grilles, you may want to consider using a professional installer. On some cars, the grilles are held by screws or spring clips. The screws will
be obvious, the spring clips won’t.
If there are screws, remove them, put them in a safe spot, and remove the grilles. To remove
a clip-on grille, use your flat-blade screwdriver to gently pry up the grille. If it resists, back
off and think again about the professional install. The cost of one of these can sometimes
be less than the cost of new door panels. Some grilles are integral parts of the door panel
and are not removable. In these cases you will need to remove the entire door panel to gain
access to the speaker location. This will usually require removal of door handles, window
mechanisms, and other parts such as door pulls and lock buttons.
1. Once you get the grille off, remove the factory speakers. Save the hardware.
You may be able to reuse it to mount your new speaker.
2. Cut the supplied speaker wire in half.
3. To mount the passive crossover gently pry up on one end of the silver crossover
cover. This will expose the two center mounting holes for installation.
4. Reattach silver cover to crossover.
5. Connect speaker wires to the crossover “woofer” terminals. Attach the red wire to
the positive (+) terminal screw, and the black wire to the negative (-) terminal screw.
6. Route the driver wire from the crossover location through grommets to the
7.
mid/woofer location.
Attach the red wire to the positive terminal (larger terminal) on the driver.
Then attach the black wire to the negative terminal (smaller terminal)
on the driver.
8. Attach the red wire to the positive red wire on the tweeter. Then attach the black
wire to the negative wire on the tweeter. Make sure the clear plastic insulators fully
cover the Faston connectors otherwise you may short the tweeter leads and possibly
damage your amplifier.
9. Strip 1/4" (6 mm) of plastic insulation from the cut ends of the driver and
tweeter wires. Connect the positive and negative wires to the woofer and
tweeter out on crossover.
10. Drilling may be required to accommodate the installation of your MOMO MMC
Component Series Drivers.
11. Using the hardware retained from the factory speaker or the screw clips supplied
with the Polk/MOMO speaker, secure your new speaker to the car panel.

Installing the Mid/Woofers in Non-Factory Locations
If you have decided to install your Polk/MOMO Series mid/woofers in locations other than
those provided by the automobile manufacturer, make certain that the location you choose
is clear of all obstructions, both in front of and behind the panel, before you proceed. Pay
particular attention to window mechanisms and any body panels critical to the structural
integrity of the vehicle. The mounting depths and cutout diameters of your Polk/MOMO
Series mid/woofers are listed with all the other important specifications at the end of
this manual.
1. Cut a hole in the panel (5 inches or 12.7 cm hole for the MMC6500,
4-5/8 inches or 11.75 cm hole for the MMC5250).
2. Use the speaker grille as a template for marking the locations of the
four screw holes.
3. Drill the holes with a 1/8" bit.
4. Attach the screw clips to the car panel at the hole locations.
5. Cut the supplied speaker wire in half.
6. To mount the passive crossover gently pry up on one end of the silver crossover
cover. This will expose the two center mounting holes for installation.
7. Reattach silver cover to crossover.
8. Connect speaker wires to the crossover “woofer” terminals. Attach the red
wire to the positive (+) terminal screw, and the black wire to the negative (-)
terminal screw.
9. Route the driver wire from the crossover location through grommets to the
mid/woofer location.
10. Attach the red wire to the positive terminal (larger terminal) on the driver.
Then attach the black wire to the negative terminal (smaller terminal)
on the driver.
11. Attach the red wire to the positive red wire on the tweeter. Then attach the black
wire to the negative wire on the tweeter. Make sure the clear plastic insulators fully

Polk/MOMO MMC System Tweeters
One important advantage of component systems is their ability, when properly installed, to
improve the soundstage created by the music in your car. The soundstage is the musical
“picture” made up of the instruments and vocalists. The difference in the soundstage will
be dramatic depending on where you mount your tweeters. We recommend a simple experiment that will help you decide the best spot for your tweeters in your car. Here are the steps:
1. Complete the installation of your entire system except for the MMC tweeters.
2. Connect the wires provided with your tweeters to the tweeter terminals on your
Polk/MOMO crossovers. (See detailed instructions below.)
3. Without running the wires through doors or under upholstered panels, connect your
Polk/MOMO tweeters to these wires. (See detailed instructions below.)
4. Have a friend sit in the passenger’s seat while you sit in the driver’s seat, each
holding a tweeter in hand, or use double stick tape.
5. With music playing, position the tweeters in different locations around the passenger
compartment, listening for the differences caused from these placements. We recommend using vocals for this test. You will be able to determine in a short time the best
location for your tweeters. The soundstage or image should “float” above the dash
and not be localized to the physical location of the drivers or tweeters. Both passenger and driver should be able to hear both channels and a stereo image.
The Polk MMC Component tweeter offers two
mounting options for installation flexibility.
Mounting Option #1—Surface mounting the
MMC Component Tweeter
1. Using the base of the surface mount cup as a template, mark the screw hole and drill it using
a 1/8 inch drill bit. Mark the wire holes (for the
tweeter wires), drill using the 1/4-inch drill bit.
2. Attach the surface mount cup to the panel using
supplied #4 screw.
3. Cut the supplied speaker wire in half.
4. Strip 1/8" – 1/4" (3-6 mm) of plastic insulation
from the cut ends of the tweeter wire. Connect this
end of the wire to the tweeter terminals of the
crossover. Connect the red wire to the positive (+)
terminal of the crossover tweeter output and the
black wire to the negative (-) tweeter terminal.

PERFORMANCE
5. Route the tweeter wire from the crossover through grommets to the tweeter location.
Push the red and black tweeter wires through the holes in the bottom
of the tweeter cup and though the panel.
6. Slip the male fast-on connector on the red tweeter wire onto the female
connector on the red wire from the crossover and the black tweeter wire to
the black wire (Figure 2). Make sure the clear plastic insulators fully cover
the fast-on connectors otherwise you may short the tweeter leads and possibly damage your amplifier.
7. Mount the tweeters by gently pushing them into the surface mount cup. Be
careful not to pinch the wires.
8. Once the tweeter is mounted and connected, swivel the tweeter to fine-tune
the soundstage image of the system. (Figure 3)
Mounting Option #2 - Flush mounting the
MMC Component Tweeter
1. Remove the panel on which you are going to
mount the tweeter and check for proper clearance
behind it. The flush mount kit is 1-3/16 inch
Figure 4
deep. Measure to make sure there is sufficient
depth behind the spot you choose the final location.
2. Use the hole that is punched into the cardboard
packing insert as a template to mark the location
and size of the mounting hole.
3. Mark the center of the spot and cut a hole with
the 2-3/16-inch hole-saw attachment for your
power drill. Go slow. Or you can use a razor
knife instead of a drill.
4. Cut the supplied speaker wire in half.
5. Strip 1/8" – 1/4" (3-6 mm) of plastic insulation
Figure 5
from the cut ends of the tweeter wire. Connect
this end of the wire to the tweeter terminals of
the crossover. Connect the red wire to the positive (+) terminal of the crossover
tweeter output and the black wire to the negative (-) tweeter output terminal.

6. Route the tweeter wire from the crossover through
grommets location to the tweeter location.
7. Assemble cup, clamp, and machine screw loosely.
8. Route the red and black tweeter wires through the holes in the bottom
of the cup.
9. Slip the male fast-on connector on the red tweeter lead wire onto the female
connector on the red wire from the crossover and the black tweeter lead wire
to the black wire (Figure 2 page 8). Make sure the clear plastic insulators fully cover
the fast-on connectors otherwise you may short the tweeter leads and
possibly damage your amplifier.
10. Press the assembly into the 2-3/16" hole until the clamp edge is below the mounting
surface, then tighten the screw. The cup will clamp down to the surface as
the screw is tightened (Figure 4 page 9). In the case of a thick mounting surface,
the legs of the clamp can be bent outward by inserting a screwdriver through the
four rectangular holes in the cup while still mounted (Figure 5 page 9).
11. Snap the tweeter into the mounting cup, being careful not to pinch the wires.
12. Once the tweeter is mounted and connected, swivel the tweeter by applying firm
pressure to the edge of the tweeter module. DO NOT apply pressure to the grille.
13. Connect positive and negative leads to the crossover.
NOTE: To remove the tweeter assembly, place a small screwdriver
into the side slot and pry carefully upwards
Damage to the tweeter from thermal overload will result without the
protection provided by a crossover and will void your warranty.

Making Dual (Bi-Wire) Connections To Your Passive Crossover
- Using a 2-channel amp, choose SINGLE input mode and wire your speakers to the
tweeter Inputs ONLY. (Figure B)
- Using a 4-channel amp (or two 2-channel amps), choose DUAL input mode and wire
driver level amp outputs to the Woofer Inputs, and tweeter level amp outputs to the
Tweeter Inputs. (Figure C)
- For use with Polk/MOMO C400.4 Amplifier ONLY: When using the Polk/MOMO
C400.4 four-channel amplifier -- and ONLY then -- you may omit this passive crossover
and wire your speakers directly from their amp outputs on the C400.4 Amplifier, being
sure to engage the C400.4's Polk/MOMO Pre-EQ Switch allowing the C400.4 to
become your system's active crossover. THIS INSTRUCTION IS ONLY FOR THE C400.4
POLK/MOMO AMPLIFIER. With all other amps, you MUST use the passive crossover
network included with this product. Any other use will VOID THE WARRANTY.

Tweeter Level
The slide switch on the side of the crossover box adjusts the level (volume) of the tweeter
relative to the mid/woofer. Start with the switch in the bottom position and listen. If you
want a “brighter” sound, move the switch to the middle position and listen again. The
“0 dB” setting provides the greatest amount of tweeter output. -3dB and -6dB reduce
output to a greater degree. (Figure A page 10)
Polarity / Blending
If it seems that the tweeters and mid/woofers are not “blending” or working together in
harmony, try changing the polarity of both the tweeters by reversing the positive (+) and
negative (-) tweeter wires at the crossover. Reversing the absolute phase of the tweeters may
help the blending or integration of the system components, particularly if the tweeters and
mid/woofers are on different planes. In your car, that is, not your plane.
Tweeter Angle
The MMC Component tweeters may be pivoted to get the best high frequency response and
soundstage. Generally, pointing the tweeters toward the listening position will yield the best
results. But don’t be afraid to try other angles. Use the position that sounds best to you.
Pivot the tweeter module by applying firm pressure on the edge of the tweeter module.
DO NOT APPLY PRESSURE TO THE DOME ITSELF.

PERFORMANCE
Amplifier Power Requirements
Your speakers will work well with a variety of electronic components. As little as 25 watts
(RMS) per channel will deliver adequate listening levels in most cars. If you have a noisy
car or intend to play your system at loud listening levels, more power is necessary to achieve
the best performance. Consult your Polk Audio dealer for specific recommendations. We
recommend using an external power amplifier that has a power rating of 50 - 100 Watts
per channel to get the best possible performance.
Safe Limits Of Operation
Your Polk loudspeakers are made with the highest quality materials for years of trouble-free
performance. However, damage to loudspeakers can occur when an amplifier, regardless
of its wattage, is made to play at higher listening levels than its power can cleanly produce
(usually beyond the “1 to 2 o’clock” position on the volume control).
This results in very high levels of audible distortion, originating in the amplifier, which
adds a harsh, gritty sound to the music. Contrary to popular belief, a speaker is more likely
to be damaged by trying to get too much volume from a low-powered amp or receiver than
from a high-powered one.
Technical Assistance Or Service
If, after following the hook-up directions, you experience difficulty, please double check
all wire connections. Make sure that your electronic equipment is operating correctly by
hooking up another speaker to the speaker output. For example, if you are not getting
sound from the left channel speaker, connect the right channel speaker to the left output.
If you still get no sound from that side, the problem is in your amp or source electronics.
Should you isolate the problem to the speaker, contact the authorized Polk Audio dealer
where you made your purchase. Authorized Polk Audio dealers are the best source for
advice and assistance.
Call Polk Audio’s Customer Service Department at 1-800-377-7655 from 9am to 6pm,
