Thank you for purchasing JBL’s Grand Touring Series multielement auto- motive 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 exten- sive 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 par- ticular 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 result- ing from use or misuse of this product.
