WARNING: Playing loud music in anautomobile can hinder your ability to heartraffic and permanently damage your hearing. We recommend listening at low ormoderate levels while driving your car. JBLaccepts no liability for hearing loss, bodilyinjury or property damage resulting fromthe use or misuse of this product.

IMPORTANT: To get the best performance from your JBL Grand Touring®

Series amplifiers, we strongly recommendthat installation be entrusted to a qualified professional. Although these instructionsexplain how to install GTO amplifiers in ageneral sense, they do not show specificinstallation methods that may be requiredfor your particular vehicle. If you do nothave the necessary tools or experience, do not attempt the installation yourself.Instead, please ask your authorized JBLcar 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 fromyour vehicle’s battery.

• Check clearances on both sides of a planned mounting surface beforedrilling any holes or installing anyscrews. Remember that the screws can extend behind the surface.

• At the installation sites, locate andmake a note of all fuel lines, hydraulicbrake lines, vacuum lines and electricalwiring. Use extreme caution when cut-ting or drilling in and around these areas.

• Before drilling or cutting holes, use autility knife to remove unwanted fabricor vinyl to keep material from snaggingin a drill bit.

• When routing cables, keep input-signalcables away from power cables andspeaker wires.

• When making connections, make certain they are secure and properlyinsulated.

• If the amplifier’s fuse must be replaced,use only the same type and rating asthat of the original. Do not substituteanother kind.

CHOOSING A LOCATIONAND MOUNTING THEAMPLIFIERChoose a mounting location in the trunk or cargo area where the amplifier will notbe damaged by shifting cargo. Amplifiercooling is essential for proper amplifieroperation. If the amplifier is to be installedin an enclosed space, make sure there issufficient air circulation for the amplifier to cool itself.

When mounting the amplifier under a seat, ensure that it is clear of all movingseat 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 amplifieris mounted securely using nuts and boltsor the supplied mounting screws.

Mount the amplifier so that it remains dry – never mount an amplifier outside the vehicle or in the engine compartment.

POWER CONNECTIONSThe GTO amplifiers are capable of delivering extremely high power levels,and require a heavy-duty and reliable connection to the vehicle’s electrical systemin order to perform optimally. See Figure 1for connection location. Please adhere tothe following instructions carefully:

Ground ConnectionConnect the amplifier’s Ground (GND) terminal to a solid point on the vehicle’smetal chassis, as close to the amplifier as possible. Refer to the chart below to determine minimum wire-gauge size. Scrapeaway any paint from this location; use a star-type lock washer to secure the connection.

Power ConnectionConnect a wire (see chart at right forappropriate gauge) directly to the vehicle’spositive battery terminal, and install anappropriate fuse holder within 18" of thebattery terminal. Do not install the fuse atthis time. Route the wire to the amplifier’slocation, and connect it to the amplifier’sPositive (+12V) terminal. Be sure to useappropriate grommets whenever routingwires through the firewall or other sheetmetal. Failure to adequately protect thepositive wire from potential damage mayresult in a vehicle fire. When you are done routing and connecting this wire, you mayinstall the fuse at the battery.

Remote ConnectionConnect 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 levelinputs, connect the remote (REM) terminalto the source unit. If your source unit doesnot have a remote turn-on connection,connect the amplifier’s (REM) terminal tothe vehicle’s accessory circuit.

Speaker ConnectionsRefer to the application guides on thepages that follow. Speaker connectionsshould be made using a minimum of 16-gauge wire.

High-Level Input ConnectionsThe GTO75.2/75.2IIamplifiers are equipped with speaker-levelinputs that allow you to add an amplifier to head units that do not have RCA lineoutputs. The speaker outputs for thesource unit should be connected to theamplifier using the supplied connector(square four-wire plug). Remember tocheck for proper polarity. .

NOTE: When using the high-level inputs,the AUX outputs can be used to pass aline-level signal to another amplifier.

If your installation differs mark-edly, you will need to adjust the wiregauge accordingly.

IMPORTANT NOTE: If you are planning to use optional neon tubes, install thembefore making any electrical connectionsto the amplifier (refer to“Installing NeonTubes” on page 5).

CONNECTIONS – GTO75.2/75.2II

The JBL GTO75.2/75.2II amplifier can be set up for stereo or bridged-monooperation, as shown in Figures 4 and 5.

NOTE: For simplicity, Figures 4 and 5 do not show power, remote and input connections.

NOTE: Minimum speaker impedancefor stereo operation is 2 ohms.Minimum speaker impedance forbridged operation is 4 ohms.

INSTALLATION AND SETUP

SETTING THECROSSOVER(S)Determine your system plans and set thecrossover mode switch accordingly. If youplan to use the GTO75.2/75.2II to drivefull-range speakers, set the crossovermode to FLAT and skip to “Setting InputSensitivity.”

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 setthe crossover mode to HP (high pass) foryour full-range speakers. Adjust thecrossover frequency to limit bass and provide increased system volume with less distortion.

For subwoofers, choose the highest frequency that removes vocal informationfrom the sound of the subwoofer.

If using the GTO75.2/75.2II to drive a subwoofer(s), set the crossover mode toLP (low pass).

SETTING INPUTSENSITIVITY1. Initially turn the INPUT LEVEL control(s)

to minimum (counter clockwise).2. Reconnect the (–) negative lead to the

vehicle’s battery. Apply power to theaudio system and play a dynamic musictrack.

3. On the source unit, increase the volumecontrol to 3/4 volume. Slowly increasethe INPUT LEVEL control(s) toward threeo’clock until you hear slight distortion in the music. Then reduce the INPUTLEVEL slightly until distortion is no longer heard.

NOTE: After the source unit is on, red LEDs(on the top panel) will light, indicating theamplifier is on. If not, check the wiring,especially the remote connection from thesource unit. Also refer to “Troubleshooting”on the next page.

AUX OUTPUTThe GTO75.2/75.2II amplifiers areequipped with full-range outputs that canbe used to connect additional amplifiers.

NOTE: When using the high-level inputs,the AUX outputs can be used to pass aline-level signal to another amplifier.

INSTALLING NEON TUBES(OPTIONAL) 1. Using a Phillips screwdriver, remove all

screws on the amplifier’s output/powerend panel and set them aside.

2. Using a 3 ⁄32-inch Allen wrench, removeonly the screws on the amplifier’s (top)clear cover and set them aside.

3. Remove the end panel and slide thecover off. Set both parts aside.

4. Locate the enclosed hardware bag andremove the four clips. Each clip has asquare end and a larger round end.Using a round end, press two clips ontoeach neon tube (e.g., Street Glow AN9 or equivalent), as shown in Figure 13.

5. For each tube, align both clips so thesquare ends slide onto an exposedextrusion edge, as shown in Figure 9. Do not cover any screw holes. Wheninstalled correctly, each neon tube willsit under an extrusion and not be visiblewhen viewed from directly above.

6. Route each neon tube’s power cablethrough its respective NEON hole on theend panel (see Figure 13).

7. Slide the cover back into place and re-install its screws. Then, replace the endpanel and reinstall its screws.

8. Finish the installation of the neon tubesas instructed in their owner’s manual.
