If your audio system’s source unit includes a remote turn-on wire and you would prefer to use it, the amplifier will sense that you’ve used a remote turn-on wire and that connection will override the signal-sensing turn-on. If necessary, you can defeat the signal-sensing turn-on circuit by moving the Auto Turn-On switch to the “Off” position. www.jbl.com...
Connect a wire (minimum 6AWG – 13.2mm – for the GTO-1001EZ; minimum 8AWG – 8.4mm – for the GTO-751EZ and GTO 501EZ) from the amplifier’s GND terminal directly to a solid point on the vehicle’s chassis. For a good connection, use sandpaper to clear the paint from the metal surface at this chassis location.

input cOnnectiOns Input Connectors Use RCA audio cables to connect source units with preamp-level outputs to the amplifier; use the supplied bare wire- to-RCA adapters to connect to source units that don’t have RCA output connectors. Use a small Phillips screwdriver to loosen the adapter’s set screws and insert the speaker wires into the holes on the back of the adapter.
