POWERBASS AMPLIFIED BASS SYSTEM FEATURES

Built-in 150 Watt 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.

Remote Subwoofer Gain Control: This wired remote functions as a Bass Boost and can
provide 0-18dB of gain at 45Hz. The remote will not increase the output beyond the GAIN
setting on the back of the amplifier. Supplied with XXft of cable it can reach your dash even when
the BTA-8 is mounted in the trunk.

Tunnel Port Design: Large tunnel serves as a tuning port that “pushes” bass from the front
loaded woofer for maximum output using a small footprint enclosure.

Bass Reflex Single Port System: For increased efficiency at low frequencies. The corner
loaded design works to produce a concentrated bass output which is amplified by firing into hard
surfaces giving the bass “kick” normally associated with much larger woofers.

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.

BASV High Temperature Voice Coil: These specially designed resin coated high temperature
voice coils measure a full 1.5-inches in diameter to ensure high power handling and precise
linear excursion while maximizing thermal heat dissipation.

Adjustable Mounting Straps: Two adjustable mounting straps are supplied to anchor the
enclosure to your vehicle while allowing for easy removal if necessary.

Additional Features: Carpeted enclosure, acoustically transparent speaker grill, professional
mounting hardware and wiring harness adds further value to your investment.

PowerBass Autosound dealer for assistance.

IMPORTANT: This amplified subwoofer system is designed for operation in vehicles with 12-

volt 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. 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 compart-

ment. 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 end (opposite the woofer and grill end) should be facing into a corner. See the
various configurations in Fig 1.

2) Ideally there should be several inches clearance between the amplifier and the corner it is point­ing into. Make sure the open area (port) above the amplifier is not obstructed.

3) When all connections are made the final step should be to secure the enclosure using the mount­ing straps provided so it remains in place.

WARNING: Make sure where ever you choose to place the BTA-8 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.

NOTE: Due to the shifting and jarring that will occur in a vehicle, the mounting straps may stretch
or loosen. It is recommended that you check the straps regularly to ensure the enclosure remains
mounted securely.

1. HIGH INPUT

Use this High Level 4-pin Molex style input when connecting to the speaker leads directly from a factory
radio without the use of a low level convertor. Be sure to observe the correct speaker polarity (Do not use if
you are using the LOW INPUT from the RCA jacks).

2. REMOTE Gain (RJ45 Jack)

This is the connector port for the BTA Remote Gain Control. Now the amplifiers secondary gain circuit can
be adjusted from the driver’s seat.
