INSTALLATION WARNINGS AND TIPS

INSTALLATION

ABOUT THESE

INSTRUCTIONS

Installation of automotive stereo com- ponents can require extensive experi- ence with a variety of mechanical and electrical procedures. Although these instructions explain how to install Power Series multielement speakers in a general sense, they do not show the exact installation methods for your particular vehicle. If you do not feel you 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 hinder your ability to hear traffic as well as permanently damage your hearing. The maximum volume levels achievable with JBL speakers, com- bined 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.

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

Except for the P6452, each Power Series multielement speaker includes an outboard crossover for in-line con- nection to an amplifier which is required for proper operation (see Figure 7 on the next page). The attached crossover wires are keyed and color-coded to aid in correct polarity connections. Do not omit the crossover or substitute another one – doing so will damage the speaker.

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 win- dow’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.
