- 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.
- 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.
- 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.
- 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 CONNECTION
- 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 sub-woofer 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.
GTO-5EZ bridged operation (high-power for front speakers)
- Connect the left speaker to the FL (+) and FR (–) terminals
- Connect the right speaker to the RL (+) and RR (–) terminals.
- Connect the subwoofer to the Sub (+) and (–) terminals.
NOTE: You can also run one pair of left and right channels
in stereo and the other pair of left and right channels bridged for a
3.1-channel system.
GTO-3EZ Bridged operation (center channel and subwoofer
operation in a multi channel system)
- Connect one speaker to the L (+) and R (–) terminals.
- Connect the subwoofer to the Sub (+) and (–) terminals.
