POWER AND GROUND  
To assure maximum output from your amplifier, use high quality, low-loss power  
and ground cables. Soundstream 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. Determine from the chart  
below the minimum gauge power and ground wire for your application.  
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  
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 fuse is accessible on the left side of the amplifier.

SIGNAL CABLE  
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
