cOnnecting the pOWer and grOund

The GTO series amplifiers are capable of delivering extremely high power levels, and require a heavy-duty and
reliable connection to the vehicle's electrical system to achieve optimal performance. Please adhere to the following
instructions carefully.

using the connectors

GTO series amplifiers use the same type of screw terminals for power and speaker connections. This type of terminal
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 tighten
the set screw to secure the wire in the connector.

ground connection

Connect a wire (minimum 8AWG – 8.4mm
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. Use a star-type lock washer to secure the
wire's connection.
