EXTERNAL
Like all audio components, the Soundstream amplifiers must be fused near the
battery. A fuse or circuit breaker must be located within 18” of the battery. This
will prevent a fire in the event of a shorted cable. See the chart below to
determine the value of your battery fuselcircuit breaker.

The SA amplifiers employ highly efficient circuitry and a unique
design to maintain lower operating temperatures. Additional cooling may be
required if the amplifier is located in a tightly confined area, or when driving
especially low impedance loads at extremely high levels.

TURN-ON
Connect the “Remote” to the turn-on lead from the source unit. When
volts
is received, the amplifier will turn on. Soundstream’s Remote200 20 gauge turn
on lead works perfectly.
When mounting the amplifier, it should be securely mounted to either a panel in
the vehicle or an amp board or rack that is securely mounted to the vehicle. The
mounting location should be either in the passenger compartment or in the trunk
of the vehicle, away from moisture, stray or moving objects, and major electrical
components. To provide adequate ventilation, mount the amplifier so that there
are at least two inches of freely circulating air above and to the sides of it.
CABLE
Depending on your application, you may use one, two, or three pairs of signal
cables to drive your amplifier. To guarantee optimum performance, use a
quality cable that will be easy to install and has minimal signal loss such as
Soundstream’s
or SL.1.
SWITCHES
Set Input and Crossover switches to the appropriate positions (see pages 15
17).
SPEAKER CABLE
Use a high quality, flexible, multi-strand cable for best performance and
longevity. Soundstream Speaker120 160 (12 and 16 gauge) are ideal.
3. MOUNTING THE AMPLIFIER
a. Using the amplifier as a template, mark the mounting surface.
b. Remove the amplifier and drill the holes.
WIRING
c. Mount the amplifier to the surface using the provided hardware.
4.
a. Run and connect the audio signal and remote turn-on cables to the amplifier
from the source unit.
b. Carefully run the positive cable from the amplifier to a fuse or circuit
breaker within 18 inches of the battery.
C. Then connect the fuse or circuit breaker to the battery.
Leave the circuit
breaker off or the fuse out until everything is bolted down.
d. Secure the ground cable to a solid chassis ground on the vehicle. It may be
necessary to sand paint down to raw metal for a good connection.

e. Double check each and every connection!

the source unit is playing, you should have sound coming from the speakers.

LEVEL SETTING
HEAD UNIT
The input levels are adjusted by means of the input level controls located on the
front of the amplifier.
In the ideal situation, all components in the audio system reach maximum
undistorted output at the same time. The reason is because an amplifier will
only make what comes into it bigger. So, if you send it a distorted signal from
the head unit, it is going to amplify distorted information. The same thing holds
true if an outboard processor or crossover begins to distort before you have
maximum output from the amplifier. By setting all components to reach clipping
at the same time, you can maximize the output of your system.
Stereo driving 1 pair of
speakers in full range
Follow the below procedure for the quickest, easiest means of setting the levels:
1. Turn the amp’s input levels to minimum position (fully counter-clockwise).
2. Set source unit volume to approximately
of full volume.
3. While playing dynamic source material, slowly increase the amplifier’s
input level until a near maximum undistorted level is heard in the system.
