Inputs and Outputs
Class D Power Amplifier:
This amplifier utilizes a Class D amplifier design, which allows it to generate more
power than other amplifier designs while producing less heat and providing
High Gloss Chrome-Plated Finish:
This amplifier has a high-gloss chrome-plated finish on the top and on all
sides. A pair of white cotton gloves is included with the amplifier to
prevent finger-print smudges when handling and mounting the amp.
Digital Voltmeter: On the top
of this amplifier is a digital voltmeter with cobalt blue illumination.
The interior circuit board illuminates as well.
Cooling Fan: There are two built-in cooling fans on the top of this amplifier, which
are activated whenever the amplifier receives a signal from the remote turn-on
lead. If the remote turn-on lead is connected to your radio, then the cooling
fans will run whenever your radio is turned on. The amplifier will shut
down if the internal temperature reaches 158 degrees F.
Bass Boost Gain Remote Control:
This amplifier includes a bass control port which is designed to work with the
wired, remote-mounted bass boost control (included). When the bass boost
control is used, you can adjust the bass boost level for the amplifiers speaker
output from 0 to 18dB.
Bridged Connection: This
amplifier includes a second bass control port which allows you to use two
Audiobahn mono amplifiers to drive a single subwoofer, and adjust the bass boost
level of both amplifiers using a single bass boost control. Simply wire the bass
boost control to the first amplifier, then use the included phone-style jack to
connect the two amplifiers using the Bridged Connection ports.
Variable Subsonic Filter: A subsonic
(infrasonic) filter allows you to filter out extremely low bass frequencies that
may rob power from frequencies that the system can reproduce without distortion.
Use of the infrasonic filter allows better amplifier efficiency and better
audible sound. The subsonic filter in this amplifier is continuously
variable from 15Hz to 40Hz.
Phase Shift Switch: The phase
shift switch allows you to select 0 or 180 degrees. When this amplifier is used
to power a subwoofer (or subwoofers), the phase shift switch can be used to
prevent phase cancellation of low frequencies that are output by the subwoofer.
Matching the phase of your subwoofers with the phase of other speakers in your
system ensures bass response does not suffer due to phase cancellation.
Soft-Start Circuitry: The
amplifier automatically turns on a few seconds after you turn your vehicle's
ignition switch to ACC or ON. The power indicator on the side of the
amplifier lights when the amplifier is on.
Terminals: The amp has
nickel-plated, heavy-duty set screw terminals.
- Thermal: shuts off the amp
when the operating temperature reaches 158 degrees F
- Input Overload: shuts off
the amp as a result of low voltage or over-voltage
- Short Circuit: shuts off the
amp due to speaker or DC short
- DC Offset: protects speakers
from damage caused by DC current
Left Side of Amplifier
- Variable Gain Control: a
rotary control that allows you to match the input sensitivity of the amp to
the particular source unit you are using
- Subsonic Frequency Control:
a rotary control that allows you to filter out unwanted bass frequencies.
The subsonic filter in this amplifier is continuously variable from 15Hz to
- Variable Bass Boost Control: a
rotary control that allows you to adjust the level of bass boost from 0dB to
- Low-pass Frequency Control:
a rotary control that allows you to adjust the frequency of the low-pass
crossover from 50Hz to 150Hz
- Phase Shift Switch: lets you
select 0 degrees or 180 degrees
- Master/Slave Switch: lets
you select between "Master" and "Slave" when bridging
amplifiers to drive a single sub.
Left Side of the Amplifier
- Line-In: left and right RCA
- Line-Out: left and right RCA output
jacks, which allow you pass full-range signals from this amplifier to
another amp in a daisy-chain configuration
- Remote: phone-style jack for
bass boost control
- Bridged Connection:
phone-style jack for bass boost control
Right Side of the Amplifier
- Speaker Terminals: one +/-
pair of nickel-plated set screw terminals (each terminal is 0.25" wide)
- BATT (power): nickel-plated
set screw terminal (accepts 4-gauge wire)
- GND (ground): nickel-plated
set screw terminal (accepts 4-gauge wire)
- REM (remote turn-on): nickel-plated
set screw terminal (terminal is 0.31" wide)
- Fuses: five 30-amp fuses

Wiring Recommendation: This
amplifier uses five 30-amp fuses, so its fuse rating exceeds that of typical 4
gauge wiring kits, which tend to include a 60-amp fuse. For 150-amp fuse
protection, an ANL wafer style fuse is required, but none of the 4-gauge wiring
kits include an ANL-style fuse holder. Since pre-packaged amplifier wiring kits
cannot be used alone, you may purchase all the necessary items separately, or
you may use a pre-packaged 4 gauge wiring kit along with an ANL-style fuse
holder and a 150-amp ANL wafer fuse. If you do not use a wiring kit with the
necessary additional items, the separate parts and wiring needed to install this
amplifier are as follows:
- 1 ANL wafer-style fuse holder
capable of accepting 4 gauge wire
- One 150-amp ANL wafer fuse
- 2 power rings for 4 gauge cable
- 4 gauge power cable (to connect the
battery to a fuse holder and the fuse holder to the amplifier)
- 4 gauge ground cable
- Remote turn-on cable (speaker wire
can be used as remote turn-on cable)
- 1 stereo RCA patch cables
- Speaker wire
