5. With music playing, position the tweeters in different locations around the passenger
compartment, listening for the differences caused from these placements. We recom-
mend using vocals for this test. You will be able
to determine in a short time the best location for
your tweeters.
The Polk dX3000 tweeter offers two mounting options
for installation flexibility.
Mounting Option #1- Surface flat or angle base
mounting the dX3000 Tweeter
1. Using the base of the surface mount cup as a tem-
plate, mark the screw hole and drill it using a 1/8
inch drill bit. Mark the wire hole (for the tweeter
wires), drill using the 1/4 inch drill bit.
2. Attach the surface mount cup to the panel using
supplied #4 screws.
3. Push the tweeter wires through the hole in the
bottom of the cup and through the panel.
4. Cut the wire supplied in the box in half.
(Check that the connector ends are the same as
those on the tweeter.)
5. Connect wires from the tweeter terminals of the crossover to the tweeter wires. Be sure
that connector ends are the same as those on the tweeter. Connect the white striped
wire strand to the (+) terminal of the crossover tweeter output and to the red wire on
tweeters (Figure 2).
6. Mount the tweeters by twist-locking them onto the base,
being careful not to pinch the wires.
Mounting Option #2 - Flush mounting the dX3000 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 inch deep. Measure to make sure there is
sufficient depth behind the spot you choose.
2. Use the template which is provided as a separate sheet in the owner’s manual to mark
the location and size of the mounting hole.
3. Mark the center of the hole and cut a 2.1 inch hole with razor knife or
reciprocating saw.
1. Cut a hole in the panel. The grilles supplied with the dX Series drivers can be used as a tem
plate for marking the cutout holes.
2. Using 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 tweeter wire in half.
6. 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.
7. Using a crimping tool, attach faston connectors to the speaker end of each of the wires
going from the crossover to the mid/woofer.
8. Remove the mesh grille from the grille frame and pass the wire through the grille frame.
9. Slip the faston connectors onto the input terminals on the mid/woofers. Be sure to attach
the wire with the white stripe to the positive (+) terminal, and the un-striped wire to the
negative (-) terminal.
10. Place the speaker into the grille frame and line up the screw holes with the screw
clips on the car panel.
11. Secure the speaker/grille frame assembly to the car panel with the supplied screws.
12. Place the mesh grille in the grille frame.
dX 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 experi-
ment 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 dX3000 tweeters.
2. Connect the wires provided with your tweeters to the tweeter terminals on your
dX crossovers.
3. Without running the wires through doors or under upholstered panels, connect your
dx tweeters to these wires.
4. Have a friend sit in the passenger’s seat while you sit in the driver’s seat, each holding
a tweeter in hand.
