IGH LEVEL CONNECTIONS (OPTIONAL)
High Level inputs have been included to connect the amplifier to a radio without low-level
outputs (i.e. factory radio). This connection will allow you to connect directly to the
speaker output of the radio with out the need of an external adapter.
Determine the type of radio you have and make one of the following connections.
CAUTION!
Before making any connections determine the type of radio to avoid possible
damage to amplifier and/or radio.
