AUTOMOTIVE LOUDSPEAKERS Grand Touring® Series GTO320, GTO420, GTO6420, GTO520, GTO620, GTO630, GTO7520, GTO920, GTO930 Owner 's Manual Thank you for purchasing JBL's Grand Touring Series multielement automotive loudspeakers. In order that we may better serve you should you require warranty service on your new speakers, please retain your original purchase receipt and return the enclosed warranty registration card. Important: Installation of automotive stereo components can require extensive experience in performing a variety of mechanical and electrical procedures. Although these instructions explain in a general sense how to install GT Series loudspeakers, they may not show the exact installation methods for your particular vehicle. If you feel you lack the necessary tools or experience, ask your authorized JBL car-audio dealer about professional installation options. Installation Warnings and Tips · Always wear protective eyewear when using tools. · Turn off all audio systems and other electrical devices before you start. Disconnect the (­) negative lead from your vehicle's battery. · Keep speakers in their package(s) until final installation. When moving a speaker, always rest it with the cone or dome facing up. Never use force to install any speaker. · 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. Caution: In some cars, fuel tanks may be located directly beneath the rear deck. Check for adequate speaker-basket clearance before considering this location! · Before drilling or cutting holes, use a utility knife to remove unwanted fabric or vinyl to keep material from snagging in a drill bit or saw. · For door installations, check the clearance with the windows in both closed and open positions and verify that a mounted speaker will not interfere with the window crank or with the power-window mechanism. · If mounting speakers elsewhere, check for clearance around rear-deck torsion bars, glove box or other structural elements. · Do not mount speakers where they will get wet. Warning: Playing loud music in an automobile can permanently damage your hearing as well as hinder your ability to hear traffic. We recommend listening at low levels while in your car. JBL accepts no liability for hearing loss, bodily injury or property damage resulting from use or misuse of this product. 02 Typical installation of the GTO320, GTO520, GTO7520, GTO920 and GTO930 speakers with grilles as shown in Figure 1.

Note: The GTO320 and GTO7520 are designed for direct replacement of factory speakers behind original factory grilles; therefore, they do not contain the grilles and trim ring shown in Figure 1. Note: Some installations may require some or all of the mounting ears to be removed from the GTO420. Remove your original speakers first to determine whether any mounting ears must be removed. 03 Installation of the GTO6420 speaker as shown in Figure 3. Figure 2b. Mounting Ears Removed Figure 3.

Note: To install the GTO6420 in European cars with elliptical openings, detach the speaker from the metal adapter. 04 Installation of the GTO620 and GTO630 as shown in Figures 4a, 4b, 4c and 4d. The GTO620 and GTO630 use JBL patented Intermount IITM 's mounting system. Intermount II provides for easy installation of these speakers in many standard and nonstandard locations that will accommodate a 6-1/2" speaker. Figure 4a. Figure 4b.
