POWERBASS AMPLIFIED BASS SYSTEM FEATURES
Built-in High Powered Amplifier: Contains a high power Class A/B monaural amplifier
complete with chassis mounted adjustable Gain, Low Pass Filter and Bass Eq controls for sonic
integration into most existing factory or aftermarket car stereo systems and engineered perfectly
to power the subwoofer.
Heavy-duty Box Design: This enclosure is constructed from non-resonant 5/8” panels that
have been glued, braced and sealed. Each box is finished in a stylish two tone RFG aviation
grade vinyl covering.
Bass Reflex Single Port System: Utilizing a Bass Reflex design offers increased efficiency
of low frequencies. To accomplish this, a flared Venturi port tube is used for exact tuning and
virtually no port noise (breathing) resulting in tight bass.
Remote Subwoofer Level Control: This wired remote functions as a Bass Level control and
can provide 0-12dB of gain at 45Hz. The remote will not increase the output beyond the GAIN
setting on the amplifier. Supplied with 18ft of cable it can reach your dash even when the bass
enclosure is mounted in the trunk.
Polypropylene Cone with Rubber Surround: A thermoplastic polymer cone was selected to
help resist moisture and other elements while the rubber surround offers more excursion as well
as protection against deterioration than other materials.
KSV High Temperature Voice Coil: These specially designed resin coated high temperature
Kapton® voice coils measure a full 2-inches in diameter to ensure high power handling and
precise linear excursion while maximizing thermal heat dissipation.
Additional Features: Vinyl enclosure, professional mounting hardware and wiring harness
adds further value to your investment.

UNPACKING THE ENCLOSURE
Every attempt has been made to transport your new PowerBass RTA subwoofer system safely. Carefully
unpack the enclosure and inspect it thoroughly for any damage that may have occurred during shipping. Notify your local PowerBass dealer immediately should you notice any damage prior to installing

INSTALLATION EXPERIENCE
Installation of PowerBass Autosound Speakers requires experience with a variety of mechanical and
electrical procedures. This manual only provides general installation and operating instructions. If you
have any reservations about your installation skills or lack the proper tools, please contact your local
PowerBass Autosound dealer for assistance.
IMPORTANT: This amplified subwoofer system is designed for operation in vehicles with 12volt Negative ground electrical systems only.
ENCLOSURE PLACEMENT TIPS AND RECOMMENDATIONS
Your PowerBass Amplified Bass system must be properly placed in the vehicle for optimum performance. Choose a structurally sound location to mount your PowerBass amplified subwoofer
enclosure. The output of the woofer needs to be “corner loaded” against the walls of the vehicle to
produce the most bass (hard surfaces work best). Since the output of the woofer will be “corner
loaded”, the best location is likely to be to the front or rear corner of a trunk or luggage compartment. However, don’t be afraid to experiment with the placement as a little time and effort can have
a great effect on the amount of bass produced. Below are some placement suggestions:

1) The amplifier heatsink end (opposite the woofer and port tube end) should be facing into a
corner. See Fig 1.
2) Ideally there should be several inches clearance between the amplifier heatsink and the corner it
is backed up to. Make sure the open port beside the woofer is not obstructed.
3) When all connections are made the final step should be to secure the enclosure using the mounting brackets provided so it remains securely in place.
WARNING: Make sure where ever you choose to place the enclosure it’s a dry location on a solid
surface. Take care that none of the mounting screws will pierce any wiring harnesses, brake or fuel
lines, the vehicles fuel tank, spare tire or any other parts of the vehicle. Some or all of these may
be located behind or under the mounting surface.

ENCLOSURE DIMENSIONS AND SPECIFICATIONS
NOTE: The speaker system must be secured to protect the enclosure from moving. Before final
mounting, be sure to check the sound one last time and make sure the enclosure is properly placed
to produce the desired bass output. Use the two mounting brackets provided and secure them to
the enclosure as shown in the drawing above.
When mounting in a trunk, try to make sure the enclosure is positioned in a manner that packages
and luggage will not slide and hit the enclosure or the woofer.
In some cases where there is no flat or even mounting area, it may be necessary to use a wooden
board to fasten the enclosure to and properly secure the mounting brackets.
NOTE: Do not obstruct the port opening.
