4cOnnecting the pOWer and grOundThe GTO subwoofer amplifiers are capable of delivering extremely high power levels, and require a heavy-duty andreliable connection to the vehicle’s electrical system to achieve optimal performance. Please adhere to the followinginstructions carefully.using the connectorsGTO subwoofer amplifiers use the same type of screw terminals for power and speaker connections. This type ofterminal is easy to use, provides superior current transfer and allows the easy connection of large-gauge wire.To use the connectors, use a Phillips screwdriver to loosen the connector’s set screw, insert the bare wire and tightenthe set screw to secure the wire in the connector.LoosenScrew InsertWire TightenScrewground connectionConnect a wire (minimum 6AWG – 13.2mm 2 – for the GTO-1001EZ; minimum 8AWG – 8.4mm 2 – for the GTO-751EZand GTO 501EZ) from the amplifier’s GND terminal directly to a solid point on the vehicle’s chassis. For a goodconnection, use sandpaper to clear the paint from the metal surface at this chassis location. Use a star-type lockwasher to secure the wire’s connection.-PowerConnectorsAudio System Head UnitRemote Turn-On (optional)> #18 AWG (0.82mm 2 ) Wire> #6AWG (13.2mm 2 ) Wire – GTO-1001EZ> #8AWG (8.4mm 2 ) Wire – GTO-751EZ/GTO-501EZ+12V18"(46cm)> #6AWG (13.2mm 2 ) Wire – GTO-1001EZ> #8AWG (8.4mm 2 ) Wire – GTO-751EZ/GTO-501EZ120A Fuse (GTO-1001EZ)80A Fuse (GTO-751EZ)50A Fuse (GTO-501EZ)Chassis Ground(bare metal)
