HELPFUL HINTSBEFORE YOU BEGIN

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:

ENGLISH

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.

*Not applicable to the TA850C & BTA850FH TA850C & BTA850FH are 2 Ohm products

Low-Level Inputs:

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

ENGLISH

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.

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.

ENGLISH

®

POWER WIRE

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

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

OPTION TWO:

When you are using this option

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.

TROUBLESHOOTING

Am I In Phase?

If your inputs are out of phase and you turn the balance

ENGLISH

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.

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. channels is wired
out of phase with the other. 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.

Do You Have A Phase Problem?

If the bass response in your application appears to be lower
then you expected or sounds muffled and or distorted, you
may be experiencing Phase Cancellation.

source material could just be recorded in error. Also speaker
placement and the acoustics of the listening environment can
effect the phase. No matter what or where the cause is located,
the solution is an easy one.

PHASE CORRECTING PROCEDURE

Disconnect all but one Bazooka

®

from your system. Be sure
that any loose wire connections are insulated to avoid the
chance of short-circuiting any of the electronic equipment.
Listen to the system and take note of the level of the Bass
Response. Connect the next Bazooka

®

and compare the level
of the combined output to that of the single unit. If the Bass
Response increases, the Phasing is correct and you can repeat
this process on the next Bazooka. If the level of the Bass
Response drops, the Phasing is incorrect and you should reverse
the speaker connections to this Bazooka
In short to INCREASE IS GOOD, to DECREASE IS BAD! Using
this method, any number of Bazooka

and compare again.

®

subwoofers can be kept

in absolute phase.

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 130 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 common sense and practice SAFE LISTENING!

ENGLISH

Phase Cancellation

When two speakers in the same frequency range produce
sound waves that are inverted from one another or 180° out
of phase, the sound waves will cancel each other out to some
degree. This effect will be heard as a drop in the output level
and/or a muffled or muddy quality in the Bass Response. The
source of this Phase Cancellation can be at any point in the
signal path. The obvious cause of this problem would be a
speaker connection that was reversed in polarity, but that is
not always the case. Sometimes amplifier channels will shift
phase 180° for no good reason, or a signal processor could
have a setting for phase that has been set incorrectly or the
