CONNECTING THE POWER AND GROUNDThe GTO subwoofer 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 ConnectorsGTO subwoofer 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 ConnectionConnect a wire (minimum 6AWG – 13.2mm2 – for the GTO-1001EZ; minimum 8AWG – 8.4mm2 – for the GTO-751EZ and GTO 501EZ) 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.

Power Connection1. Connect a wire (minimum 6AWG – 13.2mm2 – for the GTO-1001EZ; minimum 8AWG – 8.4mm2 –for the
GTO-751EZ and GTO-501EZ) directly to the battery’s positive (+) terminal.
2. Install a fuse holder for a 120A fuse (GTO-1001EZ), 80A fuse (GTO-751EZ) or 50A Fuse (GTO-501EZ) 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-1001EZ = 120A fuse; GTO-751EZ = 80A fuse; GTO-501EZ = 50A fuse.)
SUBWOOFER CONNECTIONConnect the subwoofer to the amplifier’s Sub (+) and (–) terminals.

Subwoofer
GTO Subwoofer Amplifier
Always connect the (+) terminal on the amplifier to the (+) terminal on the subwoofer and the (–) terminal on the amplifier to the (–) terminal on the subwoofer.
IMPORTANT: Make sure the (+) and (–) bare wires do not touch each other or the other terminal at both the amplifier terminals and subwoofer terminals. Touching wires can cause a short circuit that can damage the amplifier.
NOTE: The minimum subwoofer impedance is 2 ohms.
CONNECTIONS
IMPORTANT: Disconnect the vehicle’s negative (–) battery terminal before beginning the installation.
If you have not already done so, remove the two end caps that cover the amplifier’s connectors as explained in Mounting the Amplifier, above. This will provide easier access to all of the amplifier’s connectors.
AUTO TURN-ON SWITCHNo remote turn-on connection is necessary because GTO amplifiers include signal-sensing turn-on, which will turn the amplifier on when it receives an audio signal at any of its input connectors. The amplifier will automatically turn off approximately five minutes after the input signal ceases.
If your audio system’s source unit includes a remote turn-on wire and you would prefer to use it, the amplifier will sense that you’ve used a remote turn-on wire and that connection will override the signal-sensing turn-on. If necessary, you can defeat the signal-sensing turn-on circuit by moving the Auto Turn-On switch to the “Off” position.

INPUT CONNECTIONS
Input Connectors
Use RCA audio cables to connect source units with preamp-level outputs to the amplifier; use the supplied bare wire-to-RCA adapters to connect to source units that don’t have RCA output connectors.
Use a small Phillips screwdriver to loosen the adapter’s set screws and insert the speaker wires into the holes on the back of the adapter. Tighten the set screws to secure the wires.
Loosen Screw
Insert Wire
Tighten Screw
Always connect the (+) speaker wire to the (+) terminal on the adapter and the (–) speaker wire to the (–) terminal on the speaker.
IMPORTANT: Make sure the (+) and (–) bare wires do not touch each other. Touching wires can cause a short circuit that can damage the source unit or the amplifier.
When you’re finished, plug the adapter into the appropriate input connector on the amplifier.
• You can use either input connector to connect a source component with a single mono subwoofer output.
BASS BOOSTThe Bass Boost control provides up to 12dB of bass boost at 45Hz. Set this control according to your personal taste, but be careful not to set the control at a high enough level to cause audible distortion or bottoming of your subwoofer.
POWER/PROTECTION LED
Power/ Protection
LED
The GTO amplifier Power/Protection LED’s color indicates the amplifier’s operational status:
• LED is orange: Normal operation (power is on)
• LED is off: Amplifier is in standby mode
• LED is red: Amplifier is in protect mode
If the amplifier is in the protect mode (the LED is red), see Troubleshooting, on page 9.

TROUBLESHOOTING
If your amplifier isn’t performing the way you think it should, check to see if the problem is covered in this section before calling your dealer or contacting JBL customer service.
PROBLEM CAUSES AND SOLUTIONS
No sound (the amplifier’s Power/ Protection LED is off):
• Check that the amplifier’s +12V and GND connections have been properly made.
• Check if the fuse on the +12V wire located near the battery is blown; if so, replace it with an identical fuse.
• Check all amplifier fuses; if any are blown, replace them with identical fuses.
• If you are using the amplifier’s REM connection for turn-on, check that the wire is properly connected to the audio system’s remote turn-on wire or to the vehicle’s ACC power terminal.
• If you are using the amplifier’s Auto Turn-On circuit for turn-on, check that the amplifier’s Auto Turn-On switch (on the amplifier’s bottom panel) is set in the “On” position.
No sound (the amplifier’s Power/ Protection LED is orange):
• Check that all amplifier input and speaker connections have been properly made.
• Check that the amplifier’s Gain control is not turned all the way down.
• Check that the vehicle audio system’s source unit’s volume control is not turned all the way down.
• If you have connected an optional Remote Bass Control (sold separately) to the amplifier, check that it is not turned all the way down (fully counterclockwise).
No sound (the amplifier’s Power/ Protection LED is red):
• Confirm that the vehicle’s electrical system is supplying between 9V and 16V DC to the amplifier. If the supply voltage is outside of this range, correct the condition before attempting to use the amplifier.
• If the amplifier has overheated, wait until it has cooled down before attempting to use it again.
• Disconnect all speakers from the amplifier and attempt to turn it on again:
– If the amplifier turns on (the Power/Protect LED is orange), there is a short circuit in one or more of the speaker wires. Correct all short circuits before reconnecting the speakers to the amplifier.
– If the amplifier does not turn on (the Power/Protect LED is still red), contact your authorized JBL dealer for assistance.
• If the optional Sub Channel Level control is connected to the amplifier, check that it is not turned all the way down (fully counterclockwise).
Sound is too quiet, even with the vehicle audio system’s head unit volume turned all the way up:
• Check the amplifier’s Input Level switch. If it is set to “Hi1,” turn the amplifier’s Gain controls all the way down and re-set the Input Level switch to “Low.” Then perform the Set the Gain procedure, on page 7, again.
Sound in the subwoofer is distorted:
• If the Input Level switch is set in the “Low” position, change the setting to “Hi1” and perform the Set the Gain procedure, on page 7, again for those channels.
• While listening to bass-heavy music, turn the Bass Boost control all the way down, and then gradually increase it until the distortion begins to return. Reduce the Bass Boost control setting slightly to eliminate the distortion and leave it set there.
• Check that the distortion is not originating from the vehicle audio system’s source unit.
The amplifier’s Gain LEDs constantly illuminate red while the amplifier is operating:
• Set the amplifier’s Gain LEDs switch in the “Off” position.
