can be driven with either one or two pairs of stereo inputs. If your
source unit has front and rear outputs, you can take advantage of its fading
capability by driving the multi-channel amplifiers with two pairs of input. When
operating your Soundstream amplifier in mono, only one input is necessary.
On Soundstream amplifiers, pairs of channels may be bridged for mono operation.
To do so, simply put the stereo switch into the “mono” position and follow the
mono wiring (Right Positive goes to speaker’s positive; Left Negative goes to
speaker negative).

POWER AND GROUND
To assure maximum output from your amplifier, use high quality, low-loss power
and ground cables. Soundstream SA amplifiers incorporate gold-plated barrier
strips for maximum power transfer and protection from corrosion. The screw
terminals back out for use with spade & ring terminals, as well as bare wire.

CIRCUIT BREAKERS/FUSES
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.

INSTALLATION AND MOUNTING
I.
AMPLIFIER LOCATiON
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.
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.

SWITCHES
Set Input and Crossover switches to the appropriate positions (see pages 15

MOUNTING THE AMPLIFIER
a. Using the amplifier as a template, mark the mounting surface.
b. Remove the amplifier and drill the holes.
c. Mount the amplifier to the surface using the provided hardware.

Power up the system and look at the LED and it should be lit. There may be a
2 - 3 second delay from the time the source unit is turned on to the time the LED
on the amp turns on, which is normal. Once the amplifier power LED is on and
the source unit is playing, you should have sound coming from the speakers.

LEVEL SETTING
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.
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
3. While playing dynamic source material, slowly increase the amplifier’s
input level until a near maximum undistorted level is heard in the system.
