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 profes-
sional 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
mid/woofer location.
7. 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.
