About This Manual

To attain maximum amplifier perfor- mance, we encourage you to read the remaining pages before installing and operating your new JBL Decade power amplifier. Especially review the Appli- cations section for ideas on designing and expanding your system. Also, save these instructions for future reference.

Important: Installation of automotive stereo components can require extensive experience in performing a variety of electrical and mechanical procedures. Although these instructions explain how to install a JBL Decade power amplifier in a general sense, they do not show the exact installation methods for your partic- ular vehicle. If you do not have the expe- rience, do not attempt the installation yourself; instead ask your Authorized JBL Car-Audio Dealer about professional installation options.

Installation Precautions and Notes

•The JBL Decade Power amplifiers have five levels of circuit protection that mon- itor the amplifier and will shut it down if the electrical system voltage drops below 5Vdc or exceeds 18Vdc, tempera- tures are above 194° F (90° C), short cir- cuits occur or current draw exceeds product specifications. For best perfor- mance, check the intended mounting site to make sure the operating environment does not create conditions that will trigger circuit protection.

•Prior to installation, turn off all audio systems and other electrical devices. Also disconnect the (–) negative lead from the vehicle’s battery.

•At the installation site, locate and make a note of all fuel lines, hydraulic brake lines and electrical wiring. Use extreme caution when cutting or drilling in and around these areas.

•Check clearances on both sides of a planned mounting surface before drilling any holes or installing any screws. Remember that mounting screws can extend behind the mount- ing surface.

•Always wear protective eyewear when using tools.

•When routing cables, keep input signal cables away from power cables and speaker wires.

•When making connections, make sure that each connection is clean, insulated, and properly secured. Observe the polarity markings on the rear panel. Refer to the application drawings to set up the amplifier for operation in stereo, bridged-mono, bi-amp or tri-mode con- figurations.

•If the amplifier’s fuse must be replaced, use only the same rating and type as a replacement. Do not substitute another kind.
