WARNING
High powered audio systems in a vehicle are capable of generating Live Concert high
levels of sound pressure,Continual exposure to excessively high volume sound levels may
cause hearing loss or damage.Also,operation of a motor vehicle while listening to audio
equipments at high volume levels may impair your ability to hear external sounds such as;
horns,warning signals,or emergency vehicles,thus constituting to a potential traffic hazard.
In the interest of safety,Consumer Electronics recommends listening at lower volume levels
While driving.

B.VARIABLE LOW-PASS FILTER(40Hz-250Hz)
WIRING CONNECTIONS
For use as a dedicated subwoofer channel,set filter switch to LPF .Adjust variable
crossover frequency with control as desired.The amplifier input circuit filters out
everything above 40....250Hz(depends on the adjustment of the frequency control),
so only the deepest bass notes are amplified.
A.CONNECTING THE POWER
CAUTION:
AS A PRECAUTION,IT IS ADVISABLE TO DISCONNECT THE VEHICLE S BATTERY BEFORE MAKING CONNECTION
TO THE +12 VOLTS SUPPLY WIRING.
C.VARIABLE HIGH-PASS FILTER(40Hz-250Hz)
For use as a dedicated high ranged channel,set filter switch to HPF .The input
circuit filters out all frequencies below 40Hz....250Hz.
4/8 GAUGE(Or thicker if planning for additional Amplifiers)wire is recommended for both the
power and ground wires.12 Gauge,for the remote turn wire.Both types are
available at most Mobile Audio Dealers or Installation Shops.
D.BASS BOOST
By using the bass boost function the deepest bass notes at 50Hz are emphasized.
(1)GROUND:To Vehicle Chassis
To avoid unwanted ignition noise caused by ground loops,it is essential that the
Amplifier be grounded to a clean,bare,metal surface of the vehicles chassis.
BASS BOOST
NOTE:
GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FT.(1 METER).

(2)+12Volt(Fused) Constant Power:To Battery(+)
Due to the power requirements of the Amplifier,this connection should be made
directly to the positive (+) terminal of battery.For safety measure,install an in-line Fuse
Holder (not included) as close to the battery positive (+) terminal as possible with an
ampere rating:not to exceed total value of fuses in Amp.

(3)Remote Turn-On Input:To Power Antenna output of Car Stereo
NOTE:
DO NOT CONNECT THESE HIGH LEVEL INPUT WIRES IF YOU ARE USING THE LOW LEVEL INPUT RCA JACKS.
CAUTION
NOTE THAT ONLY POSITIVE(+)WIRES ARE USED.DO NOT CONNECT SPEAKER NEGATIVES.
This Amplifier is turned ON remotely when the vehicle s stereo is turned ON .
NOTE:
IF YOUR SOURCE UNIT DOES NOT HAVE AN ACTIVE +12 VOLT LEAD WHEN IT IS TURNED-ON,YOU CAN
EITHER INSTALL AN AUXILIARY SWITCH,OR YOU CAN TAP-INTO AN IGNITION LEAD;NOTE HOWEVER,THAT
YOUR AMPLIFIER WOULD TURN-ON,EVERY TIME YOU START YOUR CAR IF YOU CHOSE THE IGNITION OPTION.

INPUT SENSITIVITY(LEVEL) CONTROL

In order to achieve maximum signal-to-noise performance,this control adjusts the signal
level from your Car Stereo/Source,to match the Amplifier sensitivity.It is NOT a volume
control.

To adjust,proceed as follows:
a.Set INPUT LEVEL Control at mid-point.
b.Listen for audible distortion as you increase the Car Stereo VOLUME control.If none
is heard,turn the adjustment level control toward to MAX in stages,until the onset of
audible distortion is heard,then decrease to MIN level prior to the immediate
point of audible distortion.
C.If distortion is immediately heard,turn control to MIN until the sound is clear.
NOTE:
NOT PERFORMING ABOVE ADJUSTMENT PROCEDURE AND/OR SIMPLY SETTING THIS CONTROL AT OR NEAR
MAX POSITION,MAY INDUCE ELECTRICAL AUDIO NOISE INTO THE SYSTEM.

F.CONNECTING LOW LEVEL INPUTS (RCA Jacks)
NOTE:
DO NOT USE IN CONJUNCTION WITH HIGH LEVEL INPUT WIRES.
Wire routing is CRITICAL for NOISE FREE PERFORMANCE,Observe the following:
1.Always use high quality RCA type shielded cables.
2.Always use the shortest lenght possible.If the cable is too long,make an S type
loop(not a coiled loop)in the center of the cable to take up any excess.
3.Never cut the shielded cable and re-splice it.
Input Sensitivity Control
4.Never route any Amplifier input cables near nor parallel to speaker outputs,high
energy ignition wires,nor near computer controlled ignition circuit units (Computer
units may be found behind or under the dash panel in late model cars).

POWER INDICATOR LED
This METER LAMP will illuminate when the amplifier is turned ON .If it fails to illuminate,
check the power connections to the Amplifier and fuses.
PROTECTION CIRCUIT
Should the Amplifier be SHORT CIRCUITED overloaded or overheated,the protection
circuit will SHUT-DOWN the Amplifier.

CAUTION
THIS AMPLIFIER WAS DESIGNED TO BE USED WITH EITHER 2 OHM STEREO/CHANNEL OR 4 OHM EACH
MONO BRIDGED CHANNEL.IN THE CASE OF TRI-MODE OPERATION,USE EITHER 8 OHM STEREO CHANNEL
SPEAKERS AND 4 OHM SUB OR VICE VERSA.SEE THE SECTION TRI-MODE FOR FURTHER INFORMATION
ON PROPER USE.

(C)TRI MODE
TRI MODE OPEATIONAL OUTPUT allows a Crossover(Subwoofer) to be operated in MONO
mode while the main speaker is playing in stereo.
Leave the Crossover(Subwoofer)Switch on"FULL" position.
Use a 100Volt,non-polar capacitor for a high pass crossover and a wire coil (inductor)to
block high frequencies from the Crossover (Subwoofer)as shown in the figure below.
Capacitor and inductor values as written in the below determine the crossover
frequencies.
The front and rear channels of this amplifier get this capability.
Only the rear left and right channels are shown below.
