CIRCUIT BREAKERS/FUSES 

Like all audio components, the REFERENCE405s amplifier 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 correct fuse value. 

 

INTERNAL 

The REFERENCE405s amplifier is fused with automotive-type fuses.  In the 
event of blown power supply fuses, the “Fault” indicator on the top panel will 
light.  The fuses are accessible via a plastic plug on the bottom of the 
amplifier.  See the chart below to determine the fuse value.  Never replace 
the fuses with a higher value than what is supplied.  This may result in 
amplifier damage and will void the warranty!

REMOTE TURN-ON 

Connect the “Remote” to the turn-on lead from the source unit.  When +12 
volts is received, the amplifier will turn on. 

 

SIGNAL CABLE 

Use a high-quality cable that will be easy to install and has minimal signal loss 
to guarantee optimum performance.  Soundstream’s DL1 and SL1 are 
ideal. 

The REFERENCE405s amplifier will accept up to 8 gauge speaker cable.  Use 
a high quality, flexible, multi-strand cable for best performance and longevity.
