EX2545 Special Instructions
The EX2545 has two break-away “tabs” to allow easy placement in tight locations
(see Figure 3). Remove only the tab(s) which allow the speaker to fit. Secure the speaker
with at least two opposing tabs.
EX 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 EX2500 tweeters.
2. Connect the wires provided with your tweeters to the tweeter terminals on your
EX crossovers.
3. Without running the wires through doors or under upholstered panels, connect your
EX tweeters to these wires.
4. Have a friend sit in the passenger’s seat while you sit in the driver’s seat, with tweeters
temporarily taped in place.
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.
Installing the Mid/Woofers in Non-Factory Locations
If you have decided to install your EX Series II 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 EX Series II
mid/woofers are listed with all the other important specifications at the end of this manual.
1. A paper template for marking the cutout holes is in the speaker carton
2. Cut a hole in the panel
3. Using the paper template, mark the locations of the four screw holes
4. Drill the holes with a 1/8" bit
5. Attach the screw clips to the car panel at the hole locations
6. Attach 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
7. Run wires from your amplifier or radio to the crossover. Attach these wires to the
crossover input terminals. Remember to route them away from low level electrical
cables and use grommets when passing through doors. Attach the red wire to the
positive (+) terminal screw, and the black wire to the negative (-) terminal screw
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 red wire to the positive (+) terminal, and the black 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
