XL MARINE CERTIFIED WOOFER FEATURES
FreeAir Design: Optimized for use in infinite baffle applications such as a boat hull or
car trunk.
Polypropylene Injected Cone: Chosen for its strong yet lightweight body this water-
proof woofer cone has UV inhibitors to minimize cracking and fading.
Powder Coated White Basket: This method of painting provides resistance to chip-
ping, scratching and rust—while giving a uniform, durable high-quality finish. Applying
this finish allows us to use a steel basket in a marine environment that is much stronger
than plastic and can support a large motor structure without cracking.
TPO Thermoplastic Polyurethane Surround: A synthetic material known for its tough-
ness and flexibility, the black TPO surround rejects water, sun and salt-spray while at the
same time offering superior cone-edge suspension.
Kapton Voice Coil and Treated Damper: A Kapton voice coil former gives the speaker
increased power handling while the textile damper has been specially treated to repel
moisture and maintain uniform shape.
Voice Coil Protection: Red and black tinsel lead insulation not only easily identifies
positive and negative inputs, but also prevents against corrosion thus increasing the life
of the speaker.
Additional Features: Moisture sealed basket rings for snug water tight fit, marine grade
stainless steel hardware, and gold plated connection terminals for protection against
corrosion.

WIRING GUIDELINES
It is highly recommended that you seek an authorized PowerBass dealer to properly
setup, wire and install your marine woofer(s) for optimum performance.
Your XL Marine Woofer is a 4-ohm Single Voice Coil subwoofer. There are multiple ways
to wire your woofer(s) depending on your amplifier and system configuration. It is impor-
tant 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 offers this capability.
Always observe the amplifiers minimum stable impedance and do not go below what is
recommended by the manufacturer!
Below are several types of wiring configurations for a 4-ohm single voice coil speaker:
Series, Parallel and Series Parallel. Note that it is possible to change the impedance or
load by how the speakers are to be wired and the quantity of the woofers used.

INSTALLATION EXPERIENCE
Installation of marine audio speakers can require extensive experience with a variety of
mechanical and electrical procedures. Although this application guide explains how to
install a PowerBass Xtreme marine woofer in a general sense, it may not show the exact
installation method for your particular situation. If you feel unsure about personally in-
stalling the speaker system, don’t attempt the installation yourself. Ask your Authorized
PowerBass audio or marine dealer about professional installation options.
GENERAL INSTALLATION TIPS
Your PowerBass XL marine woofer was specially designed for providing high-fidelity
sound out in the harsh marine environment. Despite the rugged construction, it is pos-
sible to damage your speaker if it is improperly used. Overdriving the system and causing
the sound to distort will cause permanent damage to the speaker. Playing loud music in
a marine environment can permanently damage your hearing, as well as limit your ability
to hear other marine traffic.
1. Be sure to carefully read and understand the instructions before attempting to install this product.
2. Turn off the audio system. For safety, disconnect the negative lead from the battery prior to begin-
ning installation.
3. For easier installation, we recommend that if additional wiring is required, you run all wires prior to
mounting your speaker in place.
4. The marine environment can quickly accelerate corrosion so always use the highest quality con-
nectors for a reliable installation and minimal signal or power loss.
5. Always use caution before you drill or cut! Be careful not to puncture gas tanks, fuel lines, hydraulic
lines or electrical wiring when working on any vessel.
6. Never run speaker wires underneath or exposed on the vessel, keeping the wiring behind cover
provides the best protection from environmental elements.
7. Avoid running any speaker wire or signal cables near the vessel’s electrical system to prevent noise
from “bleeding” into the audio system.
8. Correct speaker polarity must be observed. Speakers wired out of phase will have little bass output.
Follow the wiring directions carefully.
9. Leave a little slack in the speaker wire for easier installation, this will prevent pulling or stretching
the wire and possibly causing a connection to come loose.
10. Always protect your speakers during installation; it is a good idea to keep the speakers in their
original package until they are ready to be mounted.
