If a low level RCA signal source is not available, you may still wire the models 100SX, 200SX,
and 400SX with high-level or speaker level outputs from your head unit. However, only
speaker leads from a "floating ground" system may be used (see diagram below). Use the strip
connector located on the end of the amplifier to make this connection. The strip connector
should be connected with the front or rear, 2 channels of your head unit.
Note: The speaker leads from a "common ground" head unit systems should not be connected
to the hi-level input terminals of the following connections.
HIGH LEVEL CONNECTIONS (OPTIONAL)
TWO CHANNEL CONNECTIONS:
FLOATING GROUND RADIO (MOST COMMON TYPE)
CAUTION! Before making any connections determine the type of radio to avoid possible
damage to amplifier and/or radio.
