installation before you begin!
ENGLISH
Locate an area in the rear of the vehicle where you would like to place
the Bazooka speaker systems. The location you have selected must
meet the following requirements in order for the Bazooka to be properly
installed in the vehicle:
1) The woofer (grill end) should be facing into a corner. (See
vehicle placement recommendations on pg. 5-6)
2) Ideally, there should be 2 to 4 inches between the woofer and
the corner it is pointing into.
3) The mounting area should be carefully checked to be sure
that the mounting screws will not damage the gas tank,
electrical wiring, fuel lines, or the spare tire during the mounting
of the strap bases.
4) The strap mounting bases should be screwed securely to a
rigid surface that is part of, or anchored to, the structure of
the vehicle.

DO NOT substitute the fuse included with the Amplified Bazooka
subwoofer with anything other than the SAME fast blow current
rated fuse. Substitution or deletion will void the product's warranty
and may cause damage to your car or the amplifier.
SHOULD I USE HIGH OR LOW LEVEL INPUTS?
If the source unit has only speaker outputs, use the high-level inputs
of the Amplified Bazooka subwoofer. If the source unit has both high
and low level outputs, we recommend using the high level inputs
over the low level inputs, due to the configuration of the Amplified
Bazooka subwoofer's balanced input circuit. Not all head units, even
those that promise high output voltage in their marketing materials,
indeed have high-voltage RCA outputs. Because of this, Bazooka
Mobile Audio recommends using the speaker level inputs when in
doubtthey will always provide sufficient drive level to the amplifier.
PLEASE NOTE THAT THE WIRING IN A FACTORY STEREO MAY NOT BE
ELECTRICALLY IN PHASE EVEN WHEN YOU HAVE MADE THE PROPER
CONNECTIONS.
Take the time after you make your wire connections to run through
the quick phase check procedure in the AM I IN PHASE? section at
the end of this manual, and NEVER USE BOTH high and low-level
inputs at the same time!

High-Level Inputs:
If the source unit has both front and rear speaker outputs, use
only one set of speaker outputs for the high-level input of the
Amplified Bazooka. Connect the GREEN wire from the 14-pin
Molex plug of the Amplified Bazooka subwoofer to the source
units left (+) positive speaker output. Connect the GREEN W/BLACK

procedure at the end of this manual to confirm that your inputs
are in correct electrical phase and the proper bass response is
being produced.
Low-Level Inputs:
ENGLISH
If your source unit only has low-level RCA phono jack output, use only
the low-level inputs of the Amplified Bazooka. Connect the low-level
RCA phono jack inputs of the Amplified Bazooka subwoofer to the
source with a shielded RCA patch cord. To avoid possible noise problems,
be sure to run the patch cord away from all power wires and factory
wire harnesses. When using the low-level inputs DO NOT make any
connections to the Green and Gray high-level input wires of the
Amplified Bazooka subwoofer and make sure these wires are insulated
to avoid the possibility of a short circuit.
or grease after you finish mounting the ground wire to prevent rust.)
REMOTE TURN ON OPTIONS
OPTION ONE:
When you are using this option with all amplified Bass Tubes
models: For the most versatility the Orange Remote Turn On Wire
should be connected to the source unit's "Accessory", "Auto-Antenna"
or "Remote" lead -- any of which will supply 12 Volts positive when
the source is turned on.
OPTION TWO:
ENGLISH
®
POWER WIRE (All Models)
The power wire must be fused and connected directly to the positive
terminal of the battery to provide a power source with a low voltage
drop and low noise. Do not make the power connection at the fuse
block or any point other than the battery. Improper power sources
can reduce output and cause distortion.
The fuse holder should be connected to the battery's positive terminal.
The fuse is designed to prevent fire or damage to your car, should the
battery wire short to ground. Wait to insert the fuse into its holder
until all wire connections have been made.
If it is necessary to lengthen the battery wire, add the required length
between the amplifier and the fuse holder, not the fuse holder and
the battery. If you need to extend t he battery wire, use 16 gauge or
larger for all A100, and 12 gauge or larger for all A200 models. It is
best to use as short a wire as possible. Be sure you DO NOT run the
power wire next to the input cables of the amplifier this will induce
noise. Avoid running the power wire near the radio's antenna or
power leads, or near sensitive equipment or harnesses. The power
wire carries substantial currents and could induce noise.
GROUND WIRE (All Models)
The ground wire must be connected directly to the vehicle chassis near
the amplifier. We do not recommend extending the ground wire in
any installation, as this can cause unwanted ground loops.
The ground point in the car should be a piece of chassis metal that is
part of or welded to the main body of the vehicle. Painted surfaces
should be scraped or sanded clean to expose the bare metal before
the ground lug is bolted down. (Cover the bare metal area with paint
When you are using this option with all BTA100 AND MBTA100:
If the source does not have an Auto-Antenna lead (or if the AutoAntenna goes down during tape operation), you can connect the
Amplified Bazookas' Remote Turn On Wire to an accessory or ignition
point at the vehicle fuse block. In this configuration, the Amplified
Bazooka subwoofer will be on whenever the ignition is on. This
method may allow noise or turn-on-and-off transients to become
amplified when the source unit is not in use, and therefore is a less
desirable than option one. Locate the Auto/Off Jumper Loop located
on the wiring harness; SAS ships the Amplified Bazooka subwoofer
with this Jumper in the ON Position. The Quick Disconnect YELLOW
On/Off Jumper Loop must be plugged into the harness.

ADJUSTING THE CROSSOVER A200 ONLY
The built-in crossover on the Amplified Bazooka subwoofer is an 18 dB per
octave electronic low pass filter, it has a 60 Hz to 250 Hz variable crossover
point. Select the crossover point that you feel best fits your system design. Set
the potentiometer labeled XOVER to the point you selected, 60 Hz being all
ENGLISH
the way to the left (counterclockwise) and 250 Hz being all the way to the
right (clockwise). When you have set the crossover, proceed to the next step.
All A200 MODELS
Remote Bass Control and Crossover (RBCM-RS):
If you find you like to vary the crossover point in addition to changing
the level of bass depending on what you are listening to and want an
easy way to make this possible, you can purchase an optional Remote
Level and Crossover Control.
ENGLISH
PHASE SWITCH (All A100 MODELS ONLY)
When one of the High-level Input channels is out of phase electrically with the
other High-level Input channel, your Amplified Bazooka subwoofer will sound
as if it has little or no output and any output that is produced may sound
distorted. If you suspect that your Amplified Bazooka subwoofer is out of
phase, use the AM I IN PHASE procedure to diagnose and correct the Amplified
Bazooka subwoofer output, and proper bass response will be produced.
To correct this situation, simply flip the phase switch on the Amplified Bazooka.
When the input signal is in correct electrical phase, the level of bass output will
be greatest when the balance control of the radio is set to the center position.
SETTING THE LEVEL (ALL A200 MODELS ONLY)
Locate the potentiometer labeled LEVEL. This is the level control. Start with
the level control turned all the way to the left (counterclockwise). The bass
should be off or very low at this point. Turn up your head unit until the sound
from the existing speakers starts to clip or distort. This is the point in your
system where you will get maximum volume with the least amount of
distortion. With the head unit at this point, turn the level gain control up
slowly until the bass volume blends well with the existing high frequency
speakers. This should be the proper setting for the level gain control. Now
that the level is set, you may want to go back to the x-over control and adjust
the x-over point by ear to meet the desired sonic quality of your system design.
These Remote Controls are accessories that are available from your
Bazooka dealer or directly from Bazooka. Be sure to check out other
optional accessories for your Bazooka at

On the back of all Bazooka passive single voice coil models you will
find a terminal cup with two 5-way platinum colored binding posts,
red being positive and black being negative. Hook the positive speaker
output from your amplifier to the red positive terminal of the Bazooka.
Hook the negative speaker output from your amplifier to the black
negative terminal. Repeat these steps for each Bazooka used.
