Figure 1a Removable Mounting Ears on GTO 402, 422 Thank you for purchasing JBL's Grand Touring Series multi-element automotive loudspeakers. We've organized this manual to make your installation as simple and trouble-free as possible. Please read through it completely before proceeding. If, after having read it, you decide that you would rather leave installation to a professional, consult your JBL Grand Touring Dealer. Bend up and down repeatedly to break off or use tin snips. · Some Toyota installations may require mounting ears to be removed from opposite sides. · Some European car installations may require all four ears to be removed. Typical installation of the GTO962, 803, 963, 502, and 402 speakers with grilles as shown in Figure 2. Trim Ring Figure 2 Autosound at its Best Your JBL GT Series multi-element speakers are built to meet the same rigorous standards of construction and performance that have long established JBL renowned home and professional 's speakers. These speakers incorporate advanced materials and construction especially suited to the unique acoustic environment of modern vehicles. They are engineered to provide excellent dispersion, wide frequency response, and high power handling. Mounting Ears Removed Car Door Grille Screen Figure 1b Two-Screw Mounting Configuration Note: The GTO462, 462d, 572, 573, 4102, and 302 are designed for direct replacement of factory speakers. Therefore they do not contain the grilles and trim ring shown in Figure 2. Installation of these models simply entails reversing the steps taken to remove the original speakers. 01 Figure 3a Mounting Ring Installation of the 6-1/2" speakers as shown in Figures 3a, b, c.

Please consider the following to help you get the most from your speakers. 1. The most spacious stereo image is achieved when the left and right speakers are placed as wide apart as possible. 2. The best center image will be achieved when the distance from the left speaker and the right speaker are as equal as possible from your listening position. This is most easily achieved by placing the speakers as far forward as possible. 3. Treble is directional in nature. This means that high frequencies are reduced as you move off the tweeter's axis. If possible, angle the speakers to be pointed across the car to the listener on the opposite side. This will make each listener slightly off-axis to the tweeter that is closest to that listener, but on axis to the most distant speaker, which helps compensate for the fact that each listener is always closer to one speaker than to the other (see Figure 4). Choosing mounting locations which satisfy all of the above criteria will provide the most satisfying performance. Installation Warnings and Tips · Be careful not to cut or drill into fuel tanks, fuel lines, brake or hydraulic lines, vacuum lines or electrical wiring when working on your vehicle. Inspect behind panels before you cut or drill. · Make sure that the speaker will physically fit in the mounting location. If door mounting, check for adequate clearance with the window in both closed and open positions as well as for interference with the window crank and power window mechanism. If mounting elsewhere, check for clearance around rear deck torsion bars, glove box or other structural elements. · Do not mount speakers where they will get wet. · Make sure that it will be easy to run connecting wires to the speakers. Trace speaker wire paths before you undertake mounting. · Always disconnect the ground wire from the battery before doing any work on the vehicle. CAUTION: Fuel tanks are located directly beneath the rear deck in some cars. Check for adequate speaker basket clearance before considering this location! A Note on Power Handling As a result of their high efficiency, all JBL loudspeakers will produce reasonable volume levels in the automotive environment using very little amplifier power. However, the use of a small amplifier to attain very high volume levels could lead to overdriving the amplifier. This will generate high distortion levels which can easily damage loudspeakers, even if the rated power of the amplifier is below the rated maximum power handling of the loudspeaker! WARNING: Playing loud music over 120dB can permanently damage your hearing. The maximum volume levels achievable with JBL speakers combined with high power amplification may exceed safe levels for extended listening. When listening at high volume levels, always use hearing protection or turn it down! Figure 4 System Design A more advanced system design can be achieved by adding a GT, GTX, GTi, or equivalent subwoofer to your GT series speakers. In this case the GT series multielement speakers will be used as high and midbass frequency drivers and should have their extremely low frequencies blocked by electrical means. Active or passive crossovers can be used in order to achieve the best system fidelity and widest dynamic range. A crossover frequency of between 80Hz and 120Hz is recommended for the best imaging and widest dynamic range. 05 Service Should your loudspeaker ever need service, return it to the JBL dealer from whom it was purchased. If for some reason this is impractical, call 800-336-4JBL for your nearest warranty station. Do not return products to the JBL factory without prior authorization.
