CAUTION
To prevent damage to your speakers, please observe the following caution:
Your PowerBass Xtreme Subwoofer is made with the highest quality materials designed for years of trouble
free performance. However, damage to the speaker can occur when the amplifier, regardless of output
power, is made to play at levels higher then it was intended. At high volume levels, if the music sounds
distorted lower the volume. The audible distortion you hear is probably originating in the amplifier which
can cause the speaker cone to move out of control and force the voice coil to bottom out and slam against
the magnet assembly. Under these circumstances it will be necessary to lower the volume to just below
the point where these symptoms occur to avoid damage to the speaker. If your amplifier has a gain control,
it would be advisable to lower this control slightly to prevent this from reoccurring.
If more volume or a higher SPL (Sound Pressure Level) is desired, you should try adding additional speak-
ers to the system. By doing so, it is possible to gain significant increases in sound pressure levels. In some
cases, you may double the system’s output without any deterioration in sound quality.
REMINDER
• This speaker is heavy, so use caution when installing or handling it.
• The subwoofer enclosure must be securely & directly attached to the vehicle.
• Speakers will become very hot when the system is operated at high power continuously
for a long period of time. Never directly touch the speakers with your bare hands until the
speakers have cooled.
• Never connect only one voice coil of this Dual Voice Coil (DVC) speaker. BOTH voice coils
must be connected to the amplifier for correct operation.

WIRING GUIDELINES
It is highly recommended that you seek an authorized PowerBass dealer to properly setup, wire
and install your woofers for maximum performance.
All PowerBass 2XL Series Subwoofers use dual voice coils. The use of dual voice coils offers you more versatil-
ity in system configuration. It is important to know the limits of your amplifier to optimize its performance. It
is always better to use your subwoofer in a mono / bridged mode if your amplifier has the capabilities. There
are basically four different types of wiring configurations: Series, Parallel, Series-Parallel or Parallel-Parallel.
It is possible to change the impedance or load by how the speakers are to be wired and by the quantity of
woofers used.
Parallel wiring a dual 4 ohm sub = 2 ohm
PARALLEL SERIES
DUAL VOICE COIL WIRING
Parallel-Parallel wiring two dual 4 ohm subs = 1 ohm Series-Parallel wiring two dual 4 ohm subs = 4 ohm
Series wiring a dual 4 ohm sub = 8 ohm

INSTALLATION EXPERIENCE
Installation of PowerBass Xtreme Speakers requires experience with a variety of mechanical and electrical
procedures. This manual provides only general installation and operation instructions. If you have any reser-
vations about your installation skills or lack of the proper tools, please contact your local PowerBass Xtreme
dealer for assistance.
CHOOSING A SPEAKER ENCLOSURE
The PowerBass Xtreme 2XL Subwoofers are engineered to perform at their optimum level in a Sealed en-
closure. However, while not optimum, these woofers may also be used in vented and bandpass enclosures.
For maximum performance we recommend you have your new PowerBass Xtreme Subwoofer installed by an
Authorized PowerBass Xtreme Dealer.
• SEALED BOX: (RECOMMENDED) A sealed or acoustic suspension enclosure is easy to build and typi-
cally offers a smaller size enclosure and greater power handling. It has the most predictable frequency
and phase response; the bass response will roll off slower than that of a ported design. Sealed boxes
typically provide the best musical detail and definition. A well-designed sealed enclosure will exhibit
smooth frequency response with excellent sound quality and great low bass extension. They also exhibit
relatively accurate, punchy bass reproduction for most types of music. If a sealed enclosure is too large to
fit into a specific area of a vehicle, it is possible to decrease the recommended box volume by using 1.5
pounds per cubic feet of low density, high heat specific box stuffing material. PowerBass recommends
Fiberglass, Dacron, Poly-Fill or long fiber wool for stuffing the enclosure. (Decreasing the box enclosure
however should not exceed 20% of the recommended size.) When using any type of box stuffing mate-
rial be sure that the subwoofer’s vented pole piece is clear from any obstructions, since covering the pole
piece will result in loss of bass and can possibly cause damage to your subwoofer. The most important
aspect of a sealed enclosure is to make sure that it is airtight and solid. If your enclosure has any air
leaks or if the panels vibrate or flex, you will experience a loss of bass output. Using glue and some type
of sealant (caulk) on all seams will ensure a solid constructed box without any air leaks.
• VENTED BOX: (NOT OPTIMUM) Also known as a ported or bass reflex enclosure, this type of box is
almost as easy to construct as a sealed enclosure. This design however is more efficient and results in
an increase of bass output at certain frequencies. Although vented enclosure has an output advantage at
some frequencies, it also has a steeper rolloff, which will only affect bass frequencies below port tuning.
Air inside the port will move in phase with the subwoofer reinforcing frequencies above the F3 (-3dB
point). The SPL advantage of the vented enclosure comes from the fact that the effect of the vent tuning
reduces the excursion of the subwoofer near the tuning frequency allowing more SPL to be produced
before the subwoofer bottoms.
7

Damping material should also be used to line the internal walls to reduce any sonic reflection. Because
of the characteristics of a vented enclosure, subwoofers typically will become unloaded (act as if it is
not in a box) at frequencies of ½ octave below the enclosure tuning frequency. Using a high pass filter
/ subsonic filter will help prevent the subwoofer from unloading or exceeding its excursion capabilities.
It is important to stay within the recommended enclosure specifications. (PowerBass recommends port
placement to coincide on the same panel or baffle that the subwoofer resides on.
• BANDPASS ENCLOSURE: (NOT OPTIMUM) The most common bandpass enclosure is a combination of
a sealed and a vented enclosure working together (4th order or single reflex bandpass system). The rear
of the speaker goes into the sealed chamber while the front of the speaker goes into the vented chamber.
Because the vent produces all the sound generated from this type of enclosure, sound quality may not be
as good as a well-designed ported or sealed design. Often the sacrifice for sound quality and subwoofer
cone control is greater SPL output. However unlike a sealed or vented enclosure, you can effectively in-
crease the enclosure sensitivity with the appropriate tuning choices. You can choose to design a narrow
frequency band with very high sensitivity or choose a wide frequency band with the sacrifice of lower
sensitivity. The damping effect of the vented chamber reduces the motion of the cone so that potentially
higher sound output is achieved without the subwoofer reaching its mechanical limits. Minor deviations
from design recommendations however may result in frequency response and distortion problems.
(If you are intending to use multiple subwoofers in your system, PowerBass recommends hav-
ing separate chambers for each subwoofer if the subwoofers will be operated by two different
amplified signals. This will prevent any possible cancellation.)
NOTE: Due to the vented backplate, you must allow an additional 2" behind the subwoofer when
designing your speaker enclosure.
ENCLOSURE VOLUME
To calculate the volume required for your enclosure please refer to the Recommended Enclosures secction
of this guide for your specific model number. These are listed in both cubic feet and liters. One cubic foot is
expressed as 12" x 12" x 12" = 1728 cubic inches (see picture below).

TIPS TO GET THE MOST OUT OF YOUR 2XL WOOFER
Your PowerBass Xtreme subwoofer has been meticulous engineered and designed to handle high power
musical reproduction. Despite their rugged construction, it is possible to damage your speaker if they are
improperly used. In general, you will hear distortion as a so-called warning before any damage occurs.
If you hear distortion in your system, immediately reduce the musical level to the point where the sound
retains its clarity.
1. All PowerBass Xtreme subwoofers require an initial break-in period before it will reach optimum
performance. Like any new precision machinery, allow a minimum of several days to one week with
normal daily usage to ensure that the suspension has properly been broken-in.
2. Never use only one coil on a dual voice coil subwoofer. Doing so will significantly decrease the ef-
ficiency and power handling of the speaker.
3. Be sure you supply the speakers with enough unclipped amplifier power to drive them properly.
(More damage can be done to a speaker by under-powering and clipping your amplifier than any
other way!)
4. Where possible, run your Speakers in mono instead of stereo. Most bass is reproduced in mono so
there is less chance of any cancellation if played in mono.
5. Where possible, wire your Speakers in parallel instead of series. Bass is reproduced either way but
again there is less chance of cancellation in parallel. NOTE: Be sure the amplifier you are using is
stable to the resulting impedance of the speaker load!
6. Where possible, a separate amplifier just for your subwoofers should be used with an electronic
crossover to set the frequency range.
7. Do not block the front of your speakers or ports. You want as much direct air coupling as possible.
Also be sure to round off the inside edges of the port to reduce any port noise.
8. For ported enclosures, keep in mind that you must leave at least twice the port diameter size be-
tween the subwoofer and the port itself. Leave at least one time the port diameter between the port
and any walls of the enclosure.
9. Remember the Golden Rule “Measure twice…cut once.”
BREAK IN PERIOD
To get the most from your woofer we recommend a "break-in" period of at least 40 hours at no more than
1/3 of maximum volume.
During this time the cone and spider assembly will gradually break in resulting in greater performance and
more listening enjoyment.

BOX CONSTRUCTION (SEALED OR VENTED)
The material used for enclosure walls should be solid, dense and free of voids or warps. Your enclosure
should be made ¾” or 19mm material, Finland or Baltic birch type plywood is recommended where the
enclosure will be transported frequently. Medium-density fiberboard - MDF (not chip board) can be used
on permanently installed systems. Minimum of 1” (25mm) or double ¾” (1-1/2”) baffle is recommended
on high-powered SPL applications. Corners must be strong and air tight and should not have any air leaks
or openings. Joints should be properly filled with glue that will not crack under high stress or impact. If the
integrity of the glue seal can’t be determined, hot glue or RTV caulking should be used to seal all seams.
Fiber reinforced resin may also be used to form any difficult shapes. However avoid making large panels
with resin to eliminate any chances of box flexing, cracking or ratting under high pressure. Bracing made
of 2 x 2” or 2 x 4” should be liberally applied either inside or outside the cabinet, depending on whether
the cabinet is to be permanently installed or portable. This principle applies to any walls of the enclosure
spanning more than 18” long. Any braces should also be liberally glued or screwed down on edge. Edge-
wise drilled, and countersunk holes through the braces can be used for #10-2 Flathead wood screws to
avoid the use of more expensive lag bolts. The majority of strength from an enclosure comes from the
glue. When using screws be sure to pre-drill holes to avoid splitting the wood.
NOTE: Do not mount the woofer in the enclosure within 24 hours of sealing the internal joints. The
gasses given off as the sealer cures can affect the surround of the speaker resulting in permanent
damage that will void the warranty.
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.
SUBWOOFER CROSSOVER SETTING
Your PowerBass Xtreme Sub will perform best if it is used in conjunction with a subwoofer crossover of
some kind. Using a crossover will remove unwanted high frequencies and allow them to concentrate only
on bass. The two most common types of crossovers are “passive” or “active” (electronic crossovers are
active). Many amplifiers have a built in Low Pass (LPF) electronic crossover circuit. For optimum sub-
woofer performance we recommend an initial electronic crossover setting between 80-100Hz and then
tuning the bass to your liking.

PREPARING FOR INSTALLATION
NOTE: The tools listed below may be required for basic installation.
• An electric drill with bits
• Saber, circular 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 planning your installation.
• 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.
• 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.

POWER RECOMMENDATIONS
Many speaker and amplifier brands measure their power ratings in different ways. Often the stated “Max Power handling” are viewed as
continuous RMS power handling of the speaker, when actually the “Max” is generally the breaking point of the speaker. In an effort to minimize
any confusion, PowerBass has chosen to rate our Super Subs in the following manner:
NOMINAL POWER HANDLING Playing your woofer at levels below the Pe-RMS spec will allow the woofer to operate at optimum conditions
and cause the speaker minimal mechanical degradation over time.
Pe-RMS POWER HANDLING Pe-RMS is the highest power rating we assign the woofer for continuous use under normal conditions. Ex-
ceeding this power level for extended durations will result in mechanical degradation that may lead to possible failure over time.
Pe-MAXIMUM POWER HANDLING Pe-Maximum is the maximum power rating the woofer can handle for short bursts or peak transients
with clean input power. Exceeding this power level or using dirty (distorted input power) will cause thermal failure that will void the speaker
warranty.

RECOMMENDED ENCLOSURES
Please note that these enclosure volume recommendations are for the internal airspace inside the enclosure and include the displace-
ment of the subwoofer and ports. When choosing your enclosure type, please pay close attention to your specific woofer, failing to use
the correct enclosure may result in lower power handling and poor sound quality. To calculate the internal airspace required,
take the internal dimensions of the box. First multiple these number by themselves and then divide this sum by 1728. (W
x H x D) / 1728.
Please contact your authorized PowerBass Autosound dealer for other designs and specifications. (Even though these subwoofers
can be used in a ported enclosure, PowerBass recommends a sealed enclosure for optimum performance and sound
quality.)
