Power Connection
1. Connect a wire (minimum 8AWG – 8.4mm
2
– for the GTO-804EZ; minimum 10AWG – 5.3mm
2
– for the
GTO-504EZ) directly to the battery’s positive (+) terminal.
2. Install a fuse holder for a 50A fuse (GTO-804EZ) or 40A fuse (GTO-504EZ) 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-804EZ – 50A fuse; GTO-504EZ – 40A 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.

Connectors
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.
Stereo operation
• Connect the front speakers to the FL and FR (+) and (–) terminals.
• Connect the rear speakers to the RL and RR (+) and (–) terminals.
