INSTALLATION
WARNING: Playing loud music in an automobile can hinder your ability to hear traffic and permanently damage your hearing. We recommend listening at low or moderate levels while driving your car. JBL accepts no liability for hearing loss, bodily injury or property damage resulting from the use or misuse of this product.
IMPORTANT: To get the best performance from your JBL Grand Touring
®
Series amplifiers, we strongly recommend that installation be entrusted to a qualified professional. Although these instructions explain how to install GTO amplifiers in a general sense, they do not show specific installation methods that may be required for your particular vehicle. If you do not have the necessary tools or experience, do not attempt the installation yourself.
Instead, please ask your authorized JBL car audio dealer about professional installation.
INSTALLATION
WARNINGS AND TIPS
• Always wear protective eyewear when using tools.
• Turn off the audio system and other electrical devices before you start.
Disconnect the (–) negative lead from your vehicle’s battery.
• Check clearances on both sides of a planned mounting surface before drilling any holes or installing any screws. Remember that the screws can extend behind the surface.
• At the installation sites, locate and make a note of all fuel lines, hydraulic brake lines, vacuum lines and electrical wiring. Use extreme caution when cutting or drilling in and around these areas.
• Before drilling or cutting holes, use a utility knife to remove unwanted fabric or vinyl to keep material from snagging in a drill bit.
• When routing cables, keep input-signal cables away from power cables and speaker wires.
• When making connections, make certain they are secure and properly insulated.
• If the amplifier’s fuse must be replaced, use only the same type and rating as that of the original. Do not substitute another kind.
CHOOSING A LOCATION
AND MOUNTING THE
AMPLIFIER
Choose a mounting location in the trunk or cargo area where the amplifier will not be damaged by shifting cargo. Amplifier cooling is essential for proper amplifier operation. If the amplifier is to be installed in an enclosed space, make sure there is sufficient air circulation for the amplifier to cool itself.
When mounting the amplifier under a seat, ensure that it is clear of all moving seat parts and does not affect the seat adjustments. Mount the amplifier so it is not damaged by the feet of backseat passengers. Make sure that the amplifier is mounted securely using nuts and bolts or the supplied mounting screws.
Mount the amplifier so that it remains dry – never mount an amplifier outside the vehicle or in the engine compartment.
Figure 1. Terminal connection end plate.
POWER CONNECTIONS
The GTO amplifiers are capable of delivering extremely high power levels, and require a heavy-duty and reliable connection to the vehicle’s electrical system in order to perform optimally. See Figure 1 for connection location. Please adhere to the following instructions carefully:
Ground Connection
Connect the amplifier’s Ground (GND) terminal to a solid point on the vehicle’s metal chassis, as close to the amplifier as possible. Refer to the chart below to determine minimum wire-gauge size. Scrape away any paint from this location; use a startype lock washer to secure the connection.
Power Connection
Connect a wire (see chart at right for appropriate gauge) directly to the vehicle’s positive battery terminal, and install an appropriate fuse holder within 18" of the battery terminal. Do not install the fuse at
this time. Route the wire to the amplifier’s location, and connect it to the amplifier’s
Positive (+12V) terminal. Be sure to use appropriate grommets whenever routing wires through the firewall or other sheet metal. Failure to adequately protect the
positive wire from potential damage may
result in a vehicle fire. When you are done routing and connecting this wire, you may install the fuse at the battery.
Remote Connection
Connect the amplifier’s Remote (REM) terminal to the source unit’s Remote Turn-
On lead using a minimum of 18-gauge wire.
NOTE: When using the speaker level inputs, connect the remote (REM) terminal to the source unit. If your source unit does not have a remote turn-on connection, connect the amplifier’s (REM) terminal to the vehicle’s accessory circuit.
Speaker Connections
Refer to the application guides on the pages that follow. Speaker connections should be made using a minimum of
16-gauge wire.
NOTE: When using the high-level inputs, the AUX outputs can be used to pass a line-level signal to another amplifier.

These recommendations assume 7' – 10' wire runs. If your installation differs markedly, you will need to adjust the wire gauge accordingly.
IMPORTANT NOTE: If you are planning to use optional neon tubes, install them before making any electrical connections to the amplifier (refer to“Installing Neon
Tubes” on page 5).

The GTO subwoofer amplifiers are single-channel amplifiers. There are two sets of terminals to make it easy to connect multiple woofers. Either set of (+/–) terminals may be used when connecting woofers.
To the right are two application diagrams to help plan your subwoofer system installation. Figures 2 and 3 show how to configure the GTO subwoofer amplifiers

INSTALLATION AND SETUP
SETTING THE
CROSSOVER(S)
Determine your system plans and set the crossover mode switch accordingly.
Initially set the crossover frequency control midway. While listening to music, adjust the crossover for the least perceived distortion from the speakers, allowing them to reproduce as much bass as possible.
Systems using a separate subwoofer set the crossover mode to HP (high pass) for your full-range speakers. Adjust the crossover frequency to limit bass and provide increased system volume with less distortion.
For subwoofers, choose the highest frequency that removes vocal information from the sound of the subwoofer.
SETTING INPUT
SENSITIVITY
1. Initially turn the INPUT LEVEL control(s) to minimum (counter clockwise).
2. Reconnect the (–) negative lead to the vehicle’s battery. Apply power to the audio system and play a dynamic music track.
3. On the source unit, increase the volume control to 3/4 volume. Slowly increase the INPUT LEVEL control(s) toward three o’clock until you hear slight distortion in the music. Then reduce the INPUT
LEVEL slightly until distortion is no longer heard.
NOTE: After the source unit is on, red LEDs
(on the top panel) will light, indicating the amplifier is on. If not, check the wiring, especially the remote connection from the source unit. Also refer to “Troubleshooting” on the next page.
REMOTE LEVEL CONTROL
All three GTO subwoofer amplifiers have inputs for an optional remote level control (RLC). This will allow the amplifier’s input level to be adjusted from the listening position. Connect the optional remote level control using the
RJ-11 jack on the side of the amplifier.
Install the control module in the front of the vehicle within easy reach of the driver.
Under the dash or in the center console are both suitable locations.
SETTING THE BASS BOOST
All three GTO subwoofer amplifiers
are all equipped with a bassboost control. This allows you to adjust the bass output of your system at 50Hz up to
12dB and enhance low frequency.
AUX OUTPUT
All three GTO subwoofer amplifiers are equipped with full-range outputs that can be used to connect additional amplifiers.
NOTE: When using the high-level inputs, the AUX outputs can be used to pass a line-level signal to another amplifier.
INSTALLING NEON TUBES
(OPTIONAL)
1. Using a Phillips screwdriver, remove all screws on the amplifier’s output/power end panel and set them aside.
2. Using a 3 ⁄32-inch Allen wrench, remove only the screws on the amplifier’s (top) clear cover and set them aside.
3. Remove the end panel and slide the cover off. Set both parts aside.
4. Locate the enclosed hardware bag and remove the four clips. Each clip has a square end and a larger round end.
Using a round end, press two clips onto each neon tube (e.g., Street Glow AN9 or equivalent), as shown in Figure 13.
5. For each tube, align both clips so the square ends slide onto an exposed extrusion edge, as shown in Figure 9.
Do not cover any screw holes. When installed correctly, each neon tube will sit under an extrusion and not be visible when viewed from directly above.
6. Route each neon tube’s power cable through its respective NEON hole on the end panel (see Figure 13).
7. Slide the cover back into place and reinstall its screws. Then, replace the end panel and reinstall its screws.
8. Finish the installation of the neon tubes as instructed in their owner’s manual.
