Congratulations on your purchase of a Bazooka Audio Input Control System. At Bazooka, we are fanatics
about accurate music reproduction. Your selection of our products for your sound system indicates that
quality sound is also important to you too. At SAS, we take great pride in manufacturing revolutionary audio
products, and through the years of engineering expertise, hand craftsmanship and critical testing
procedures, we have created this high-performance input switcher. We hope that you will take as much
pride in owning and using one of these high-quality audio products as we do designing and manufacturing
them.
When properly installed and operated, your Bazooka will give you years of clean
uninterrupted sound reproduction. Therefore, we urge you to take a few minutes to carefully read through
this manual. It will explain all of the features of your amplifier and help insure trouble free installation.
Sound can be deceiving. Over time your hearing comfort level adapts to higher volumes of sound. What may
have sounded normal can actually be too loud and harmful to your hearing. Guard against this by setting your
equipment at a safe level before your hearing adapts.
To establish a “safe level”,
Start with your volume control at a low setting.
Slowly increase the volume control until you can hear comfortably, clearly and without
distortion.
Once you have established a comfortable “sound level”, make a note of this position and do not go
above this setting
Taking a minute to do this will help prevent your hearing from being damaged and allow you to enjoy listening
to music throughout your lifetime.

SAFETY PRECAUTIONS
Fuse amplifiers power wire at the battery.
Be sure to fuse the power wire within 6” of the vehicles battery. This will protect the vehicle and CSS-3I in
case of a short circuit between the CSS-3I and battery.
Use high grade wire connectors.
To ensure maximum power transfer and secure safe connections, it is recommended to use high grade
barrier spades (for connection at amplifier if applicable) and terminal rings (for connection at battery).
Do not run any wires underneath vehicle.
Exposed wires have a chance of being cut or damaged. It is best to run all wires through the vehicle under
the carpet and/or side panels. This lends to a cleaner installation and less risk of damage.
Use caution when mounting the CSS-3I.
Remember there are many electrical wires, gas lines, vacuum lines, brake lines as well as a gas tank in the
automobile. Make sure you know where they are when mounting the amplifier to avoid puncturing lines,
shorting wires or drilling holes in the gas tank.
Run signal wires away from electrical wires.
To avoid possibility of induced noise from the vehicles electrical system (i.e. popping noises or engine noise),
run wires away from the vehicles electrical wiring.
Make all ground wires as short as possible and at the same point.
In order to reduce the chance of ground loops (i.e. engine noise), make the grounding wire as short as
possible to reduce the wire's resistance. Also, when using multiple components, make sure all units are
grounded at the same point.
Avoid sharp edges when running the wires.
To avoid the possibility of power, signal or speaker shorts, be careful not to allow the CSS-3I wires to come in
contact with sharp edges. Use a grommet to protect the wire when running through the fire wall .

FEATURES AND BENEFITS
Multiple Source Inputs
The CSS-3I’s allows for two low level inputs (RCA’s) and one Stereo 3.5mm stereo input jack (MP3 or iPod). This
gives the flexibility to choose what source input you wish to play through your amplifier.
Source Thru-puts
We have included source thru-puts for the inputs A & B. This allows you to pass the same source signal to
another CCS-3I or additional amplifiers in the system.
Remote Turn-on
Automatically turns the CSS-3I on when connected to the head unit's remote output. The CSS-3I will turn on
and off with the head unit along with the amplifier attached to the CSS-3I.
CSR Input Jack
A remote input jack has been provided for connection with optional CSR-W or CSR-I Power, Source and Volume
Control. The CSR’s allow independent control of source inputs and the volume of the amplifier(s) connected
to the CSS-3I.
Adjustable Level Control for A & B Level Inputs
Independent level matching between each input source and the power amplifier. This allows you to adjust
each source input to optimize the overall level to the connected amplifier.

MOUNTING LOCATION
Before you start the installation, it will be necessary to find a mounting location for the unit. Find a location
in which the CSS-3I will receive adequate ventilation in order to dissipate the heat it develops during
operation. Do not mount in the engine compartment.
Select the location in which you wish to mount the CSS-3I. Use caution when mounting the CSS-3I, there are
many wires, gas lines, vacuum lines, brake lines as well as a gas tank in the automobile. Make sure you know
where they are when mounting the unit to avoid puncturing lines, shorting wires or drilling holes in the gas
tank. Once you are ready, use a pencil to mark the mounting holes in the bottom panel. After you have marked
the locations of the holes move CSS-3I out of the way and drill small starter holes to make the tapping screws
easier to install. Use provided screws to tighten down the CSS-3I.

POWER CONNECTIONS
IMPORTANT! Before making any connections, disconnect the vehicles battery until the installation is
completed to avoid possible damage to the electrical system.

SIGNAL CONNECTIONS AND ADJUSTMENTS USING THE CSR-W
To make these connections, we recommend high quality RCA cables, which are available at your local Bazooka
retailer. Run signal wires away from electrical wires to avoid possibility of induced noise from the vehicles
electrical system (i.e. popping noises or engine noise).

USING CSS-3I FOR MULTIPLE ROOM APPLICATIONS
The following example shows how multiple CSS-3I’s can be connected to share one input source. The CD
Player (Input A) signal is passed to the second CSS-3I so that when “Input A” is selected, the CD player can be
played through the system in the second room.

TROUBLE SHOOTING THE SYSTEM
We have put together this trouble-shooting guide if you experience problems after installing the CSS-3I.
Please keep in mind that the majority of problems incurred are caused by improper installation and not the
equipment itself. In addition, there are many components in the system that could cause various signal
problems such as inducted electrical noise and engine noise.
Before you can properly address the problem, you must first find the component that is causing the problem.
This will take patience and a process of elimination.
