User manual JBL BASS20

[. . . ] If you feel you lack the tools or necessary experience, ask Always wear protective eyewear when using tools. Turn off all audio systems and other electrical devices before you start. Check clearances on both sides of a planned mounting surface before drilling any holes or installing any screws. [. . . ] 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 bt i. When routing cables, keep inputsignal cables away from power cables and speaker wires. When making connections, ensure that they are secure and properly insulated. If the amplifier's fuse must be replaced, use only the same type and rating as that of the original. Warning: Playing loud music in an automobile can permanently damage your hearing as well as hinder your ability to hear traffic. JBL accepts no liability for hearing loss, bodily injury or property damage resulting from use or misuse of this Wiring the Input-Signal Connections Connect a pair of signal cables with RCA-type ends between the connectors on the amplifier and the RCAtype signal connectors on the source unit. Using the amplifier as a template, mark the location of the mounting holes on the mounting surface, drill pilot holes and attach the amplifier to the mounting surface with screws. For power, remote and ground connections strip off one end of each jacket to reveal bare wire for insertion into the barrier-strip connectors. Connect a wire from the G N D connector on the amplifier to the nearest bare-metal chassis component; scrape away the paint to ensure g o o d conductivity. Next, connect a wire between the BATT terminal on the amplifier and the POS (+) terminal of the vehicle's Pass the wire through a factory-installed grommet in the firewall, or install a grommet if a factory grommet is not available. You must install, within 45 cm of the batt e r y connection, a fuse holder and fuse with the same rating as the fuse in the amplifier's chassis. This will prevent a short circuit from causing damage to the amplifier or the car.
