Power Connection

1.Connect a wire (minimum 6AWG – 13.2mm2 – for the GTO-5EZ; minimum 8AWG – 8.4mm2 – for the GTO-3EZ) directly to the battery’s positive (+) terminal.

2.Install a fuse holder for a 90A fuse (GTO-5EZ) or 70A fuse (GTO-3EZ) on this wire within 18" (46cm) of the battery’s (+) terminal. Do not install the fuse in the holder at this time.

3.Route this wire to the amplifier’s location and connect it to the amplifier’s +12V terminal. Be sure to use appropriate grommets whenever routing wires through the firewall or other sheet metal. IMPORTANT: Failure to adequately protect the positive wire from potential damage may result in a vehicle fire.

4.When you are finished routing and connecting this wire, install the appropriate fuse in the holder you installed near the battery. (GTO-5EZ = 90A fuse; GTO-3EZ = 70A fuse.)

Speaker Connections

Always connect the (+) terminal on the amplifier to the (+) terminal on the speaker and the (–) terminal on the amplifier to the (–) terminal on the speaker.

IMPORTANT: Make sure the (+) and (–) bare wires do not touch each other or the other terminal at both the amplifier terminals and speaker terminals. Touching wires can cause a short circuit that can damage the amplifier.

NOTE: The minimum speaker impedance for stereo operation is 2 ohms. The minimum speaker impedance for bridged operation is 4 ohms. The minimum subwoofer impedance is 2 ohms.

Stereo operation

Connect the front speakers to the Front L (FL) and Front R (FR) (+) and (–) terminals.

GTO-5EZ only: Connect the rear speakers, using the RL and RR (+) and (–) terminals.

Connect the subwoofer to the Sub (+) and (–) terminals.
