Installing the dX 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
perhaps 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 tweeter wire in half.
3. 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. Using a crimping tool, attach faston connectors to the speaker end of each of the wires
going from the crossover to the mid/woofer.
5. 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.
6. If the factory speaker had three screw holes, you’ll need to drill additional screw holes to
accommodate the four screw pattern of the dX mid/woofer.
7. Using the hardware retained from the factory speaker or the screw clips supplied with the
dX speaker, secure your new speaker to the car panel.
Installing the Mid/Woofers in Non-Factory Locations
If you have decided to install your dX 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 dX Series mid/woofers are listed with all the other important specifications at
the end of this manual.
Installing the Components
The dX 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 dX Series crossovers have terminals which are clearly marked for wiring connections.
Before making connections between your crossovers, and the mid/woofers and tweeters, refer
to Figure 1. The wires provided with your dX 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 positive (+) terminals of each speaker.
