User manual JBL CS6100BG

[. . . ] · Check clearances on both sides of a planned mounting surface before drilling any holes or installing any screws. Remember that the screws can extend behind the surface. · Before drilling or cutting holes, use a utility knife to remove unwanted fabric or vinyl to keep material from snagging in a drill bit. · When routing cables, keep input-signal cables away from power cables and speaker wires. [. . . ] Amplifier cooling is essential for proper amplifier operation. If the amplifier is to be installed in an enclosed space, make sure there is sufficient air circulation for the amplifier to cool itself. When mounting the amplifier under a seat, ensure that it is clear of all moving seat parts and does not affect the seat adjustments. Mount the amplifier so it is not damaged by the feet of backseat passengers. Make sure that the amplifier is mounted securely using nuts and bolts or the supplied mounting screws. Mount the amplifier so that it remains dry ­ never mount an amplifier outside the vehicle or in the engine compartment. 2 INSTALLATION POWER CONNECTIONS The CS amplifiers require a reliable connection to the vehicle's electrical system in order to perform optimally. See Figures 1, 2 and 3 for terminal connection locations. Please adhere to the following instructions carefully: Ground Connection Connect the amplifier's Ground (GND) terminal to a solid point on the vehicle's metal chassis, as close to the amplifier as possible. Refer to the wire gauge chart to determine minimum wire gauge size. Sand away any paint from this location; use a startype-lock washer to secure the connection. Power Connection Connect a wire (see chart at right for appropriate gauge) directly to the vehicle's positive battery terminal, and install an appropriate fuse holder within 18" of the battery terminal. NOTE: Minimum speaker impedance for stereo operation is 2 ohms. Minimum speaker impedance for bridged operation is 4 ohms. Front Left Front Right Figure 6.

If your system design does not include a subwoofer with the CS6100BG, set the crossover mode to FLAT and skip to "Setting Input Sensitivity. " Initially set the crossover frequency control midway. While listening to music, adjust the crossover for the least perceived distortion from the speakers, allowing them to reproduce as much bass as possible. Systems using a separate subwoofer set the crossover mode to HP (high pass) for your full-range speakers. [. . . ] For subwoofers, choose the highest frequency that removes vocal information from the sound of the subwoofer. If using the CS6100BG or CS60. 2 to drive a subwoofer(s), set the crossover mode to LP (low pass). Initially turn the INPUT LEVEL control(s) to minimum (counter clockwise). Reconnect the (­) negative lead to the vehicle's battery. [. . . ]
