turns on the amplifier when (+) 12
volt is applied to it. Connect it to
the remote turn on lead of the head

used to supply a remote turn on
signal. DO NOT connect this
terminal to constant (+) 12 volt.
5. GGrroouunndd - Connect this terminal
directly to the sheet metal chassis
of the vehicle, using the shortest
wire necessary to make this
connection. Always use wire of the

12 volt power wire. The chassis
connection point should be scraped
free of paint and dirt. Use only
quality crimped and/or soldered
connectors at both ends of this
wire. DO NOT connect this terminal
directly to the vehicle battery
ground terminal or any other
factory ground points.
