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 !

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 vehicle placement
recommendations on page 5)

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.) Ensure that the mounting base brackets are 13 apart and square before
mounting. Incorrect placement of the brackets will make final mounting difficult
or impossible (See mounting on page 8).

5.) The bracket 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!

FINISHING THE LOOK (Step 1)

In order to complete the look of your subwoofer, you will need to install
the included wire loom over the wire and attach the nozzle to the top of
the tank.

To begin, the wiring needs to be routed THROUGH the nozzle. If necessary,
begin by feeding the wire through the nozzle as shown in the picture
below. Continue feeding wire through as you push the nozzle into the top
of the tank until you hear a click. On the NOS8A, the amount of

wiring and small area of the nozzle can make this difficult. To make
this easier, Bazooka recommends twisting the nozzle assembly
around to make the wiring coil up inside the nozzle and take up
less space. Be sure not to rotate the nozzle so much that it pulls
the wires loose from their connections. Usually, one-and-a-half
turns is all that is necessary.

On the NOS8A, you will also need to install the valve knob onto the gain
control at this point.

FINISHING THE LOOK (Step 2)

Next, install the wire loom by pushing the loom onto the wire, as
shown in below. Starting from the free end and working your way up
to the nozzle. (Note: Pulling the wire loom will result in binding,
making it more difficult to put the loom in place.) Remove the
locking nut from the nozzle by turning counter-clockwise ¼ turn. Once
the wire loom is passed along the length of the wire and through the
locking nut, fold the wire loom over itself at least 5/8 of an inch, so
the end of the loom is flush with the locking nut. Slide the remaining
wire and loom through the locking nut, and screw the locking nut into
place by turning ¼ turn clockwise.

Mounting the NOS Tube:

Once you have found a suitable location, you need to mount the NOS
Tube. Mounting the unit ensures that it will give you years of trouble­free performance, and also guarantees that your unit is correctly
oriented for it to operate properly. To begin, mount the bases parallel
on the floor of the vehicle with the bases EXACLTY 13 inches apart,
from inside edge to inside edge. Mounting these brackets incorrectly
will make the final mounting steps difficult or impossible. The tall
bracket should be mounted towards the front of the vehicle, to stand
the back of the unit up, mimicking an actual NOS installation. Once
the brackets are mounted firmly to the vehicle, place the NOS Tube on
the brackets, and secure them with the enclosed mounting straps. The
straps simply screw into the brackets with the supplied hardware.

POWER WIRE (NOS8A only)

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 the battery wire, use 12 gauge or
larger for NOS8A, 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 (NOS8A only)

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 or screwed down. Cover the bare metal area with paint
or grease after you finish mounting the ground wire to prevent rust.

REMOTE TURN ON WIRE (NOS8A only)

The ORANGE wire coming out of the NOS8A subwoofers nozzle is the
Remote Turn On Wire. This wire must be connected to 12 volts switched
output from the radio or an accessory wire.

INPUT WIRING (NOS8A only)

Connect the low-level RCA phono jack inputs of the Amplified Bazooka
subwoofer to the source with a high quality, shielded RCA patch cord.
Right and Left RCAs do not matter; they are summed together internally
anyway, but both RCA connections need to be made. If you are
connecting to a factory installed radio, or if your radio does NOT have
RCA outputs, you will need to purchase a high-to-low-level converter,
available at any car audio store. To avoid possible noise problems, be
sure to run the RCA cables away from all power wires and factory wire
harnesses.

SETTING THE LEVEL (NOS8A only)

The level control on the NOS8A is the valve at the top of the unit.
The valve rotates approximately 270 degrees, with the clockwise
direction being up. DO NOT OVER-ROTATE THE GAIN CONTROL.
Broken gain controls due to over-rotation ARE NOT covered under
warranty. 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 level still 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.
