Installation Warnings and Tips JBL GTO Series Multi-Element Speakers
About These Instructions Installation of automotive stereo components can require extensive experience with a variety of mechanical and electrical procedures. Although these instructions explain how to install GTO Series multi-element speakers in a general sense, they do not show the exact installation methods for your particular vehicle. If you feel you do not have the experience, do not attempt the installation yourself, but instead ask your authorized JBL car audio dealer about professional installation options. Loud Music and Hearing Playing loud music in an automobile can permanently damage your hearing, as well as hinder your ability to hear traf�c. The maximum volume levels achievable with JBL speakers, combined with high power ampli�cation, may exceed safe levels for extended listening. We recommend using low volume levels when driving. JBL accepts no liability for hearing loss, bodily injury, or property damage as a result of use or misuse of this product. Rear Deck Precaution In some cars, fuel tanks may be located directly beneath the rear deck. Before installation, make sure there is adequate speaker-basket clearance before considering this location! About the Crossover Each GTO Series multi-element speaker includes a built-in crossover network and requires no additional external circuits for proper operation. To insure correct polarity connections, each speaker is also equipped with keyed terminals (see Figure 4 on page 3). General Care The loudspeaker grilles may be cleaned with a damp cloth. Do not use any cleaners or solvents on the grilles or the speaker cones. Installation Tips � Always wear protective eyewear when using any tools. � Turn off all audio components and other electrical devices before you start. Disconnect the negative (�) lead from your vehicle�s battery. � Keep speakers in their package until �nal 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. � 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 throughout the range of the window�s travel, and verify that a mounted speaker will not interfere with the window crank or powerwindow mechanism. � If mounting speakers elsewhere, check for clearance around reardeck torsion bars, glove box or other structural elements. � Do not mount speakers where they will get wet.
