3 PowerPlus Amplifiers Installation Before you begin the installation of your PowerPlus series amp remember, there are two ways to do things – right and twice! Use the proper installation techniques, tools and accessories to ensure that your Jensen PowerPlus series amp will put out all the power it was designed to. If necessary, seek a professional installer to have the amplifier installed correctly. Most mobile amp installations do not have the proper gauge wire for power and ground – do not let your amp be a victim of this common installation oversight! NOTE: This device is a high- power audio amplifier intended for installation in vehicles with a 12-Volt negative ground electrical system. Attempting to connect or operate the amplifier with another type of electrical system may cause damage to the amplifier or the electrical system. Installation Assistance For installation assistance, call 1- 800- 323-4815 during normal business hours, or visit jensen.com at any time. Supplies and Tools Needed To install the amplifier, you will need tools, supplies and adapters. It is best to make sure you have everything you need before you start. Supplies • Black electrical tape • Amplifier Installation Kit Tools • Cordless drill with assortment of bits • Flat-head and Philips screwdrivers • Wire cutters/strippers • Crimping tool • 12-volt test light or digital multimeter • Wire brush, sandpaper or scraping tool ( ground connection to vehicle should be a clean, unpainted metal surface) Disconnect Battery Disconnect the negative ( - ) battery cable before starting the installation. Check the battery ground (there should be two (2) ground wires coming from the battery – one going to the starter mounting bolt or engine block and another going to the vehicle chassis) and make sure the battery is grounded to the chassis with at least a # 8 gauge wire. Also check the alternator connections, making sure they are tight and free from corrosion, rust or dirt. Location and Mounting The amplifier’s compact design allows great flexibility in mounting. Common mounting locations include under the front passenger seat or in the trunk area. When selecting a location, remember that amplifiers generate heat. Select a location on a flat surface away from heat and moisture where air can circulate around the amplifier. Place the amplifier in the mounting location and mark the positions of the holes with a marker, pen or pencil. Carefully drill the mounting holes in the marked positions, then use the supplied mounting screws to securely fasten the amplifier to the mounting surface. 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. 4 PowerPlus Amplifiers 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): MODEL NUMBER MAX CURRENT DRAW MIN WIRE GAUGE 420 30A #8 840 50A #8 900 90A #4 1150 120A #4 1302 60A # 6 1304 80A # 8 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 breake...
