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 (Figure 1). 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 instal- lation, 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.

Your Polk/MOMO Series crossovers have clearly marked terminals. Before making connections between your crossovers, mid/woofers and tweeters, refer to Figure 1. The wires provided with your Polk/MOMO System have one conductor with a white stripe. Use this wire as the positive

(+)lead and connect it to the positive (+) terminals on your crossovers as well as to the posi- tive (+) 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 or a putty knife 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 driver wire (the heavier gauge of the two sets of wire) in half.

3.Remove the yellow crossover cover by squeezing the cover at the tabs. Attach

speaker wires to the crossover “woofer” terminals. Attach the wire with the white

stripe to the positive (+) terminal screw, and the un-striped wire to the negative (-)

terminal screw.

4.Route the driver wire from the crossover location to the mid/woofer location.

5.Strip 1/8” – 1/4” (4-6 mm) of plastic insulation from the cut ends of the driver wire.

6.Unscrew the binding post thumbnuts on the mid/woofers to fully expose the hole in

the terminal shaft and slip the other end of the wire into the holes in the input ter-

minals. Tighten the thumbnuts finger-tight (do not over-tighten the nuts as you

may strip the threads). Be sure to attach the wire with the white stripe to the posi-

tive (red) terminal, and the un-striped wire to the negative (black) terminal.

7.If the factory speaker had three screw holes, you’ll need to drill additional screw

holes to accommodate the four screw pattern of the Polk/MOMO mid/woofer.

8.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.
