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.
Determine from the chart below the minimum gauge power and ground wire for
your application.

CIRCUIT BREAKERS/FUSES
EXTERNAL
Like all other amplifiers, the Soundstream
amplifjers
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 fuse/circuit breaker.

INTERNAL
The Soundstream amplifiers are fused internally with automotive-type fuses.
The fuses are accessible via a plastic plug on the bottom of the amplifier. Never
replace the fuses with a higher value than what is supplied.
This may
result
in
amplifier damage and

the
warranty!
REMOTE TURN-ON
Connect the ‘Remote” to the turn-on lead from the source unit.
When
+I2
volts
is received, the amplifier will
turn
on.
SlGNAL CABLE
Depending on your application and amplifier
(SA*120,
244, or
245),
you may
use one, two, or three pairs of signal cables to drive your amplifier. To
guarantee optimum performance, use a high-quality cable that will be easy to
install and has minimal signal loss.
SPEAKER CABLE
Use a high quality, flexible, multi-strand cable for best performance and
longevity. Soundstream Speaker120 & 160 (12
&
16 gauge) are ideal.
