ELA Power Wire
The 12 gauge red wire on the 2-pin
power plug 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. 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 15 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 |

ELA Ground Wire
The 12 gauge black wire on the 2-pin
power plug 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.)

ELA Remote Turn-On
Option One
Use the 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.

ELA 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.

ELA 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.

ELA 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.

ELA 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 back of the amp, right
above the harness receptacle. SAS ships the Amplified Bazooka with
this Jumper in the Off Position. To use the Auto Turn-On Option
the Jumper must be in the On Position. The Jumper Clip must be lifted
off of the middle and right hand pins and reinserted across the
left hand and middle pins to enable the Auto Turn-On feature. This
can be done easily with a pair of needle nose pliers. With the Jumper
in the On Position, the Amplified Bazooka will turn on automatically
when it senses any music. 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.

Mounting The
Switch
The on/off switch has a variety
of mounting options.
Supplied with the switch is a mounting plate for under dash application.
Notice that one 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 on to the panel you wish to mount the switch.
Carefully cut out the mounting hole.

ELA 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 10-pin Molex
plug of the Amplified Bazooka to the source units left (+) positive
speaker output. Connect the Gray wire of the plug to the source
units right (+) positive speaker output. No (-) negative speaker
inputs are needed for High-level operation. 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 ELACrossover
The built-in crossover on the Amplified
Bazooka is a 12dB per octave electronic low pass filter, it has
a 50Hz to 250Hz variable crossover point. Select the crossover point
that best suits your system design. Set the potentiometer labeled
XOVER to the point you selected, 50Hz being all the way to the right
(clockwise) and 250Hz being all the way to the left (counter-clockwise).
When you have set the crossover, proceed to the next step.

Adjusting
the ELALevel 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.
