BTAxx100 Power Wire
The 16 gauge red wire is the 12 Volt positive power wire. It must be connected
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. Unless using the BAZOOKA F.A.S.T. system. 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 power 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, as this may induce noise.
Avoid running the power wire near the radio's
antenna or power leads, or near sensitive equipment or harness.
The power wire carries substantial currents and could induce noise.

CAUTION:
DO NOT 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 you car or the amplifier. |

BTAxx100 Ground Wire
The 16 gauge black wire 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 should be a piece
of chassis metal that is welded to the main body of the vehicle.
Painted surfaces should be scraped or sanded
clean before the ground lug is bolted down. (Cover the bare metal
area with paint or grease to prevent rust.)

BTAxx100 Remote Turn
on Options
The ORANGE wire on the Amplified Bazookas'
10-pin Molex Mini-fit Jr. connector is the remote turn on wire.
You have several options for connecting the Remote Turn-on.
Option One
- 12 Volt Remote from source unit with rocker switch
Option Two - 12 Volt Remote from
source unit
Option Three - 12 Volt Accessory
or ignition with rocker switch
Option Four - 12 Volt Accessory
or ignition
Option Five - BTAxx100's built-in
Auto Turn-On

BTAxx100 Remote Turn-On
Option One
Use an on/off switch and connect
the ORANGE Remote Turn On wire to one side of the switch. Connect
the other side of the switch 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
on/off switch will allow you to demonstrate to others, the difference
the Amplified Bazooka makes in your system, or just turn it off
whenever you desire.
When using this option the quick disconnect yellow jumper loop must be removed.

BTAxx100 Remote Turn-On
Option Two
If you do not have an on/off switch
you may hook up the ORANGE Remote Turn On wire 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. This will allow the Amplified Bazooka to be turned
on and off with the source unit.
When using this option the quick disconnect yellow jumper loop must be removed.

BTAxx100 Remote Turn-On
Option Three
If the source unit does not have an
Auto-Antenna lead (or if the Auto-Antenna goes down during tape
operation) you can connect the Amplified Bazookas' ORANGE Remote
Turn On wire to one terminal of the on/off switch and the switch's
other terminal to an accessory or ignition point at the vehicle's
fuse block. In this configuration, the Amplified Bazooka will be
on whenever the ignition and the on/off switch are both on.
This method may allow noise or turn-on and turn-off transients to
become amplified when the source unit is not in use. If this occurs,
simply turn off the on/off switch when the source unit is not
in use and this noise will be eliminated.
When using this option the quick disconnect yellow jumper loop must be removed.

BTAxx100 Remote Turn-On
Option Four
If you do not have an on/off switch
and the source unit does not have an Auto-Antenna lead you may hook
up the ORANGE Remote Turn On lead to an accessory or ignition point
at the vehicle's fuse block. This will allow the Amplified Bazooka
to be turned on by the vehicles' ignition, and remain on as long
as the key is in the accessory or run position.
When using this option the quick disconnect yellow jumper loop must be removed.

BTAxx100 Remote Turn-On
Option Five
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 inputs). Please take notice
of the On/Off Jumper Clip located on the brown and yellow wires at the end of the harness. SAS ships the Amplified Bazooka with
this Jumper in the on position. 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.
When using this option the quick disconnect yellow jumper loop must be removed.

BTAxx100 Input
Signal Connections
HIGH-LEVEL INPUTS: If the source unit
has only speaker outputs, or both low and high level outputs, use
only the Amplified Bazooka's high-level inputs. NEVER USE BOTH high
and low-level inputs at the same time! 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 with black strip to the (-) negative speaker output. Connect the Gray wire of the plug to the source
units right (+) positive speaker output. Connect the gray with black strip to the (-) negative speaker output. 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.

WARNING
- Connecting one of the Amplified Bazooka's High-level Input channels out of phase electrically with the other High-level Input channel may cause damage to the amplifier's input section. NEVER DO THIS!
NOTE:
If you are not sure of the polarity of the wires that you are tapping into connect one channel first and check it by turning on the unit and listening to it. If there is no output, turn off the unit and reverse the polarity of the inputs wires. If it still has no output, you have other problems, Check all connections. If it sounds correct, turn off the unit and connect the other channel. Turn on the unit again and listen to it, if the output increases, you are connected correctly. If the output drops or is reduced, turn off the unit immediately as it is not the correct polarity and may damage the unit. Reverse polarity of one channel and check it again, the output should increase and the connections should be correct.

LOW-LEVEL INPUT:
If the source unit only has low-level RCA phono jack output, use
only the low-level outputs of the source.
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. DO NOT make
any connections to the Green and Gray wires of the Amplified Bazooka
and be sure these wires are insulated to avoid the possibility of
a short.

Adjusting
the BTAxx100 Level Control
Locate the potentiometer labeled LEVEL.
This is the level control. Start with the level control turned all
the way to the right (clockwise). The bass should be off or very
low at this point. Turn up your head unit until the sound form 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 crossover control and adjust the crossover point by ear to meet the desired sonic quality of your system design.
