HIGH 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.
