Speaker Level Input Cable
GTA amplifiers offer a dedicated speaker level input for ease installation into
factory systems when an RCA (low level) signal is not available. Wiring code for
the cable is industry standard;
White Solid = Left Positive White w/ Black Stripe = Left Negative
Gray Solid = Right Positive Gray w/ Black Stripe = Right Negative
Warning: Do not connect both Speaker Level and RCAs into the amplifier at the
same time as damage to the amplifier may occur.
