PRACTICE SAFE LISTENING

Continuous exposure to high volumes of sound may cause permanent hear­ing loss. High powered auto sound systems are capable of producing
sounds well over 13 0 dB. Even short periods of play at high volume levels
can impair your ability to hear necessary traffic sounds and may constitute
a hazard. Please use commo n sense and practice SAFE LISTENING !

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 follo w­ing 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, f uel 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.

POWER WIRE

The 16 gauge red wire on the 14-pin Molex Mini-fit Jr. connector 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 o r any point other than the battery. Improper po wer 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 16 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.

Avo id 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 NO T substitute the 7.5 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.

10

GROUND WIRE

The 1 6 gauge black wire on the 14-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.

The ground point in the car sho uld 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 O RANGE wire on the Amplified Bazookas' 14-pin Molex Mini-fit Jr.
connector is the Remote Turn On W ire. You have several options in
co nnecting the Remote Turn On Wire. These o ptions are listed in the o rder
of 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 co nnecting
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 Bazo oka makes in your system, or you can turn the Amplified
Bazooka off whenever you desire. When you are using this configuration,
the Quick Disconnect YELLOW O n/ Off Jumper Loop MUST be disconnected
from the wiring harness.

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.

11

TURN ON OPTIONS CONT.

Notice that o ne 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 o n 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 W ire to one terminal of the SAS On/ O ff
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 O n/ O ff Switch are both
on. This method may allow noise o r turn-on-and-off transients to beco me
amplified when the source unit is not in use. If this occurs, simply turn
off the SAS O n/ O ff switch when the source unit is not in use and this
noise will be eliminated. When you are using this Option, the Quick
Disconnect YELLOW O n/ O ff Jumper Loop MUST be disconnected fro m
the wiring harness.

Option Three:

The Amplified Bazooka has a built -in Auto Turn-On Feature. If you choose to
use this feature, the Amplified Bazo oka will turn on automatically whenever
there is music present at the inputs (high level or low level input). Please
take notice of the Q uick Disconnect Yellow On/ Off Jumper Loop located
on the Amplified Bazooka wiring harness. SAS ships the Amplified
Bazooka with this Jumper Loop plugged into the wiring harness. When the
JUMPER LO O P plugged in, the Auto Turn-On O ption is in the ON position
and the Amplified Bazooka will turn on automatically when it senses any
music at the inputs. 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.

12

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 Bazo oka. 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 NO TE
THAT THE W IRING IN A FACTORY STEREO MAY NOT BE ELECTRICALLY IN
PHASE EVEN W HEN YOU HAVE MADE THE PRO PER CO NNECTIO NS.
Take the time after you make your wire co nnections 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 Bazo oka. 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. Co nnect the GRAY wire of the
plug to the source units right (+) positive speaker output. Connect the GRAY
W/ BLACK stripe wire o f the plug to the source units right (-) negative speaker output.

PHASE ALERT

When one o f the Amplified Bazooka's High-level Input channels is out of
phase electrically with the o ther High-level Input channel your Bazo oka 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.

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 fro m the
Bazooka will increase. W hen you bring the balance control back to the
center po sition the bass level will drop. This confirms that o ne of your input

13

SIGNAL CONNECTIONS CONT.

channels is wired out of phase with the other. To correct this situation, simply
reverse the connections on one of the two input channels. W hen 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 o utput, 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 fro m 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 Bazo oka and make
sure these wires are insulated to avoid the possibility of a short circuit.
