WIRING EXAMPLES
Your PowerBass Xtreme XPRO Mid Range driver uses a single 4-OHM voice coil. It is important to know
the limits of your amplifier to optimize its performance. You can vary the impedance by altering the wiring
configurations: Series, Parallel, or Series-Parallel. Choose the wiring diagram below that corresponds to
the number of speakers in your system and the impedance stability of your amplifier.
One 4-ohm speaker @ 4 ohm
Two 4-ohm speakers @ 2-ohm
in parallel
Eight 4-ohm speakers @ 2-ohm
series parallel
Two 4-ohm speakers @ 8-ohm
in series
Four 4-ohm speakers @ 4-ohm
series parallel

INSTALLATION EXPERIENCE
Installation of PowerBass Xtreme speakers requires experience with a variety of mechanical procedures
including enclosure construction. This manual only provides general installation and operation instruc-
tions. If you have any reservations about your installation skills, please contact your local Authorized
PowerBass Xtreme dealer for assistance.
CHOOSING SPEAKER MOUNTING LOCATIONS
Choosing the correct speaker mounting location will have the greatest effect of the sound quality of the
system. There are many different considerations needed when choosing the location(s) that best meet
your needs. The locations must be large enough for the speakers to fit. Care is needed to ensure that the
desired location will not affect either the mechanical or electrical operation of the vehicle.
WARNING! The use of silicone rubber to seal in a speaker will void the Warranty! If any sealing is needed
in addition to the speaker’s gasket, use caulking cord or vinyl weather strip.
PREPARING FOR INSTALLATION
NOTE: The tools listed below may be required for basic installation.
• An electric drill with bits
• Saber and jig saw
• Phillips-head and standard screwdrivers
• Wire strippers
• Crimping tool and needle-nose pliers
• Silicone sealant (for enclosures), closed cell weather-stripping (for the speakers)
INSTALLATION PRECAUTIONS
NOTE: Proceed only if you are a qualified installer otherwise; let your dealer do it.
• Always wear protective eyewear when using tools.
• Turn off all stereo and other electrical devices before you begin.
• Disconnect the (-) negative lead from your vehicle’s battery.
• Keep the speakers in the package until final installation, and always rest it with the cone facing up.
Never use force when installing a speaker.
• Locate all fuel lines, brake lines, oil lines, and electrical cables when planing your installation.

7
• Check to see if there is enough clearance behind the mounting surface before drilling holes or install-
ing screws for proper speaker ventilation.
• Also make sure there’s enough front clearance for speaker cone excursion. Failure to do this could
cause the cone to vibrate against any obstructing object damaging the speaker.
• Use a utility knife to trim away fabric from the speaker mounting hole location before drilling. It is
hard to get a good seal if you have both the carpet & subwoofer gasket between the speaker and
the enclosure.
• When running speaker wires through sheet metal, be sure to use grommets to properly insulate the
wires from metal edges.
DOOR MOUNTING
When checking for possible speaker locations in the doors, check the operation of the window and all
assemblies. There is also a stabilizer stop bar in between the door and the door jam. This bar prevents the
door from opening too far.
REAR DECK MOUNTING
In rear deck installations, check the operation of the trunk suspension springs or tension bars. These tension
bars move in the opening and closing of the trunk. You cannot be too cautious during this part of the instal-
lation. In addition do not locate the speakers too close to the back of the rear deck. Installing the far screws
may not be possible without removing the rear window.

INSTALLING THE MID RANGE DRIVER
1. Determine where the speaker will be mounted. Make sure there is a flat area large enough for the
speaker to fit properly. An uneven mounting surface can damage the driver.
2. Check to make sure the space you have selected for the speaker will not interfere with the operation of
the vehicle.
3. Using the supplied template, mark the hole with a pen.
4. Cut the hole for the speaker. A hole can be cut either with a pair of metal tin snips, a saber or jig saw.
5. Run speaker wire (not included) to the speaker. Make sure to keep wires away from sharp metal or other
rough edges. When passing through metal, use a grommet to protect the wires from sharp edges.
6. Pre drill the mounting holes using a 1/8” (3mm) drill bit.
7. Pull the wire though the speaker opening and connect to the speaker. Be sure to observe proper polarity.
8. Mount the speaker using the supplied screws.
RECOMMENDED ELECTRONIC CROSSOVER SETTINGS
For optimum performance of your range driver we recommend the following crossover frequency point setting
on each model. NOTE: Crossover settings will vary based on the speaker size.
XPRO-6.5CX (6.5 inch) mid range driver, set the crossover control at 200Hz in high pass (HPF) and 5 KHz in
low pass (LPF) for a 3 way application, OR set the crossover control at 200 Hz in high pass (HPF) for 2 way
application. A slope at each crossover will be at least 12dB/per Octave, or better .
XPRO-8CX (8 inch) mid range driver, set the crossover control at 150Hz in high pass (HPF) and 5 KHz in low
pass (LPF) for a 3 way application, OR set the crossover control at 150 Hz in high pass (HPF) for 2 way ap-
plication. A slope at each crossover will be at least 12dB/per Octave, or better .
