UPA224/UPA424 INSTALLATION Supplies and Tools Needed To install the amplifiers, 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 Phillips 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. 3 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.
