INSTALLATION

Please take time to read through this manual and plan out your installation
before you begin!

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 figures 1, 2 and 3)

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.

Be sure that your application meets all of these requirements before you
continue the installation procedure!

WIRING DIAGRAM

When using high level inputs, take the time after you make all wiring
connections to run through the AM I IN PHASE? procedure of this manual
to confirm that your inputs are in correct electrical phase and the proper
bass response is being produced.

9

POWER WIRE

The 12 gauge red wire on the 2-pin power plug is the 12 Volt positive power wire. It
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. Use 12 gauge or
larger to extend the battery wire. 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.

CAUTION

DO NOT substitute the 15 amp fuse included with the Amplified Bazooka 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.

GROUND WIRE

The 12 gauge black wire on the 2-pin Molex Mini-fit Jr. connector is the negative
ground wire. It 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.

GROUND WIRE CONT.

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 or grease after you finish mounting the ground wire to prevent rust.)

REMOTE TURN ON OPTIONS

The ORANGE wire on the Amplified Bazookas' 14-pin Molex Mini-fit Jr. connector
is the Remote Turn On Wire. You have several options in connecting the Remote
Turn On Wire. These options are listed in the order or preference recommended
by SAS. Select the option best suited for your application.

Option One:

For the most versatility the Remote Turn On Wire should be connected to one terminal of the SAS On/Off Switch,
with the other terminal connecting 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. The SAS On/Off Switch allows you to demon­strate to others the difference the Amplified Bazooka makes in your system, or to turn it off whenever you desire.

Mounting The Switch:

The SAS On/Off Switch has a variety of mounting options. Supplied with the switch is a mounting plate
for under dash applications. Notice that one end of the mounting plate is angled and the other is not. Select
the end that is best suited for your application and mount that end of the plate to the dash panel.

The switch can also be flush mounted into a flat panel or factory switch knock out panel. Be sure that the
place you choose to flush mount the switch has enough clearance behind it before you start the installa­tion of the switch. Using the supplied mounting panel as a template, etch the mounting hole on to the panel
you wish to mount the switch. Carefully cut out the mounting hole.

Option Two:

If the source does not have an Auto-Antenna lead (or if the Auto-Antenna goes down during tape operation),you
can connect the Amplified Bazookas' Remote Turn On Wire to one terminal of the SAS On/Off Switch and the
Switch's other terminal to an accessory or ignition point at the vehicle fuse block. In this configuration, the
Amplified Bazooka will be on whenever the ignition and the SAS On/Off Switch are both on. This method may
allow noise or turn-on-and-off transients to become amplified when the source unit is not in use. If this occurs,
simply turn off the SAS On/Off switch when the source unit is not in use and this noise will be eliminated.

Option Three:

The Amplified Bazooka has a built-in Auto Turn-On Feature. If you choose to use this feature, the Amplified
Bazooka will turn on automatically whenever there is music present at the inputs (high level or low level input).
Please take notice of the On/Off Jumper Clip located on the back of the amp, right above the harness recep­tacle. SAS ships the Amplified Bazooka with this Jumper in the Off Position. To use the Auto Turn-On Option
the Jumper must be placed in the On Position. The Jumper Clip must be lifted off of the middle and right hand

pins and reinserted across the left hand and middle pins to enable the Auto Turn-On feature. This can be done
easily with a pair of needle nose pliers. With the jumper in the On position, the Amplified Bazooka will turn
on automatically when it senses any music. The ORANGE wire should not be connected to anything if this
feature is being used. Be sure to insulate the end of the ORANGE wire so that it will not short to ground, as
this may damage the Amplified Bazooka.

INPUT SIGNAL CONNECTIONS

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. 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's balanced input circuit. 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 of this manual.
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 to the source units left (+) pos­itive speaker output. Connect the GREEN W/BLACK stripe wire of the plug to the
source units left (-) negative speaker output. Connect the GRAY wire of the plug to
the source units right (+) positive speaker output. Connect the GRAY W/BLA CK stripe
wire of the plug to the source units right (-) negative speaker output.

PHASE ALERT

When one of the Amplified Bazooka's High-level Input channels is out of phase electrically
with the other High-level Input channel your Bazooka will sound as if it has little or no out­put, and any output that is produced may sound distorted. If you suspect that your Bazooka
is out of phase, use the AM I IN PHASE procedure to diagnose and correct the Bazookas'
output, and proper bass response will be produced.

12

PHASE ALERT CONT.

Am I In Phase?

If your inputs are out of phase and you turn the balance control of your radio all the
way to one side, right or left, the bass output from the Bazooka will increase. When
you bring the balance control back to the center position the bass level will drop.
This confirms that one of your input channels is wired out of phase with the other.
To correct this situation, simply reverse the connections on one of the two input channels.
When the wiring 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.

LOW-LEVEL INPUT:

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 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 and make sure these wires are
insulated to avoid the possibility of a short circuit.

OPTIONAL HIGH LEVEL OUTPUT

The Amplified Bazooka has provisions for high level output to a second subwoofer. If you want
to use this feature, you can purchase a Bazooka slave unit from your authorized SAS dealer.

Be sure to use a slave unit that is the same size as your amplified unit. This is necessary
because different size woofers have different efficiencies. These efficiency differences result
in the two woofers playing at different volume levels, making it difficult to adjust the system
to the desired sonic quality.

Locate the BROWN and the YELLOW wires on the 14-pin Molex plug, connect the
BROWN wire to the RED terminal of the slave unit, and the YELLOW wire to the BLACK
terminal of the slave unit.

The Amplified Bazooka is now operating under a 2 ohm load and delivering a total
output of 120 watts of power.

13

ADJUSTING THE CROSSOVER

The built-in crossover on the Amplified Bazooka is a 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 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.

ADJUSTING LEVEL GAIN CONTROL

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
