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 ALUMINUM ENCLOSURE DESIGN:

 This enclosure is constructed from aircraft grade 

aluminum that has been acoustically tuned.

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 cable to reach your dash even when the bass enclosure is mounted under the 
seat.
 

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 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.
