POWERBASS AMPLIFIED BASS SYSTEM FEATURES
BUILT-IN HIGH POWERED AMPLIFIER: Contains a high power Class D 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.
SELECTABLE SENSITIVITY SETTING: With this button pressed in, the preamp sensitivity will accept
input voltages from 2V-10V. This will be used if High Level Inputs are connected to your amplified
enclosure. With this button left out, the preamp sensitivity will now accept 250mV-6V. This will be used if
Low Level / RCA Inputs are connected to your amplified enclosure.
DIE-CAST ALUMINUM ENCLOSURE DESIGN: This enclosure is constructed from aircraft grade
aluminum that has been acoustically tuned with the integrated custom tooled passive radiator for
optimum bass output.
REMOTE SUBWOOFER LEVEL CONTROL: This wired remote functions as the amplifier's secondary gain
circuit and can be adjusted from the driver’s seat. The remote will not increase the output beyond the
GAIN setting on the amplifier. Supplied with cable to reach your dash even when the bass enclosure is
mounted under the seat.
ALUMINUM-COATED POLYPROPYLENE CONE: 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 1
1/2
inches in diameter to ensure high power handling and precise
linear excursion while maximizing thermal heat dissipation.
AUTO TURN-ON CIRCUIT: When using the high level inputs, the amplifier will turn on automatically
when it senses a signal from your radio.

ENCLOSURE PLACEMENT TIPS & RECOMMENDATIONS
Your Powerbass Amplified Bass system must be properly placed in the vehicle for optimum performance.
Find a spot under your seats where the enclosure will not get in the way of any moving parts of the seat.
Make sure that the seat moves freely if it is adjustable.
Ideally there should be enough room around the enclosure which is also a heatsink for the amplifier so it
can remain cool.
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.
