WARNING: Do not cover the amplifier with carpets or enclose it behind interior trim panels, and do not mount the amplifier in an inverted or upside down configuration. Be sure the mounting location and the drilling of pilot holes will not damage any wires, control cables, fuel lines, fuel tanks, hydraulic lines or other vehicle systems or components. Routing Wires Proper wiring connections are illustrated on the following pages. If wiring connections are made incorrectly, the unit will not operate properly and could become permanently damaged. Follow the installation instructions carefully, or have the amplifier installed by an experienced technician. POWER Amplifiers 4 Power Wiring Charging System In some cases, the installation of just one (1) amplifier could be enough to overload your factory electrical system (i.e., alternator). Depending on the state of your electrical system and overall condition of your vehicle, you may need to upgrade your alternator and battery. After the vehicle is started, the alternator provides the power to your electrical system, not the battery. When the engine is running, the alternator is your main source of power. Upgrading the alternator should be your first consideration if you should experience a voltage drop in the system when operating your audio system. Adding capacitors and/or batteries without upgrading the alternator will only make the problem worse because these devices put an extra load on the alternator. After upgrading the alternator, capacitors and/or batteries can be installed if desired. Use the following recommended wire gauge as a guide when installing your amplifier(s): Power Terminal (+12V/B+) Connect the main power wire to the battery, within 18 inches from the positive (+) battery post, using an adequate size fuse or circuit breaker capable of handling the current of the selected power wire. A fuse or circuit breaker must be installed to prevent a possible electrical fire should the main power wire short to ground. Remote Terminal (REM) Connect the power antenna or amplifier turn-on lead from the receiver to the amplifier remote terminal.

To ensure a good ground, scrape away any paint or undercoating to expose bare metal. Use a "ring" terminal of the proper gauge and an "outside star washer" (between the chassis and ring terminal) when making your ground connection. Although you’ve scraped away the paint to expose bare metal, the outside star washer will help to "bite into" the chassis for a tight, secure ground.

POWER Amplifiers 6 Speaker Wiring The Speaker Wiring diagrams illustrate options for connecting one or two speakers. Observe the proper speaker polarity. NOTE: Power amplifiers can drive speakers with a nominal impedance range of 2~ 4-ohms. For maximum power, configure your speakers for a nominal 2-ohm load. NOTE: Do not overlook the use of the proper gauge speaker wire. The Power series of amplifiers require a minimum of 12-gauge wire.
