WARNING

High powered audio systems in a vehicle are capable of generating "Live Concert" high
levels of sound pressure, Continued exposure to excessively high volume sound levels may
cause hearing loss or damage. Also, operation of a moter vehicle while listening to audio
equipment 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 vilume levels
while driving.

Before beginning the installation, consider the following:

a. If you plan to expand your system by adding other components somrtime in the future,

ensure adequate space is left, and cooling requirements are met.

b. Should you use high or low inputs?

Your Amplifier ha been designed to accept either High-Level (speaker outputs from your
radio) or Low-Level (Pre-Amp outputs from your radio) signal source.

If your radiolsource is equipped with Pre-Amp outputs, it is possible to utilize them to drive
the Amplifier and connecting (Amplifier) to the 2 rear speakers. Then, use the built-in
power of your radio to drive the

2

front speakers.

NOTE:
DISTORTION LEVEL IS CONSIDERABLY LOWER FROM PRE-AMP (LOW LEVEL) OUTPUTS, THAN SPEAKER

(HIGH LEVEL) OUTPUTS.

C. Are your components matched? The peak power rating of your speakers must be equal

or greater than the Amplifier's. They also must be 2-8 Ohms limpedance (This information
os normally printed on the speaker magnet).

d. Consider both the length of your leads, and routing when determining the mounting

location. Pre-Amp input Jacks requir a length of high quality shielded male to male RCA
patch cord.

;

The mounting position of your Amplifier will have a great effect on its ability to dissipate the
heat generated during normal operation. It has ample heat sink for heat dissipation, and
also designed with a thermal shut-down (for heat protection) circuit, making air to be
directed over the cooling fins will improve heat dissipation dramatically. DO NOT enclose
the

amwlifier in a small box of cover it so that air cannot flow around fins.

Temperatures in car trunks have been measured as high as 175'F(80'c) in the summer time.
since the thermal shut-down point for the Amplifier is

185'F(85'c) it is easy to see that it must

be mounted for maximum cooling

capability. To achieve maximum advantage of
convection ais flow in an enclosed trunk, mount the amplifier in a vertical position, on a
vertical surface.

Cooling requirements are considerably relaxed when mounting inside the passenger
compartment since the driver will not often allow temperatures to reach a critical point.
Floor mounting under the seat is usually satisfactory as long as there is at least

1

inch(2cm)

above the Amplifier's fins for ventilation.

0

a Select a suitable location that is convenient for mounting, is accessible for wiring, and

has ample room for air circulation and cooling.

b. Use the amplifier as a template to mark the mounting holes. Remove the Amplifier and

drill 4 holes. use extreme caution, inspect underneath surface before drilling.

c. Secure the Amplifier using the screws provided.

A. CONNECTING THE POWER (Fig. 1)

CAUTION:
AS A PRECAUTION, IT

IS

ADVISABLE TO DISCONNECTTHE VEHICLE'S BAnERY BEFORE MAKING CONNECTION

TO THE +12 VOLTS SUPPLY WIRING.

418

GAUGE(Thicker if planning for additional Amplifiers) wire is recommended both the
power and ground wires. 12 Gauge, for the remote ture-on wire. Both types are
available

at

most Mobile Audio Dealers or Installation Sho~s.

(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.

NOTE:
GROUND

WIRE SHOULD NOT BE EXTENDED MORE THAN

3

FI.(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-One Input : To Power Antenna output of Car Stereo

This Amplifier is turned "0N"remotely when the vehicle's stereo is turned "ON".

NOTE:
IF YOUR RADIO DOES NOT HAVE +12 VOLT OUTPUT LEAD WHEN THE RADIO IS TURNED ON.
THE

'REMn TERMINAL ON THE AMPLIFIER CAN BE CONNECTED TO VEHICLE'S ACCESSORY CIRCUIT THAT IS LIVE

WHEN THE KEY

IS

'ON'.

B.

VARIABLE LOW-PASS FILTER (40Hz-250Hz)

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 (dependent on the adjustment of the frequency control).

so only the deepest bass notes are amplified.

fl

C. VARIABLE HIGH-PASS FILTER (40Hz-250Hz)

For use as a dedicated mid high rangd channel, set filter switch to "HPF". The inpul
circuit filters out all frequencies below 40Hz

....

250Hz.

D.

BASS BOOS1
By using the bass boost functionthe deepest bass notes at 45Hz are emphasized.

E.

CONNECTING HIGH LEVEL INPUTS (Fig.2)

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.
