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 JBL GTO17T tweeters 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 – 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 traffic. The maximum volume levels achievable with JBL speakers, combined with high power amplification, 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.

ABOUT THE FILTER

Passive filter design involves precise circuit design and component selection. Moreover, a well-designed filter circuit provides an intended electrical response, when combined with the electrical proper- ties of the speaker, to provide a particular acoustic response. Each enclosed filter has been optimized to provide a flat response when used with a JBL GTO17T tweeter.

Do not use another brand or type of passive crossover, or connect more than one tweeter to a crossover. Doing so may damage the tweeter.

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 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.

•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 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.

ABOUT PLACEMENT

Figures 1 through 3 show possible speaker placements, with Figure 1 being more desirable. We recommend using the kick panel for mounting to obtain the best staging and imaging in most vehicles.
