User manual JBL BP300.1

[. . . ] Mount the amplifier so that it is not damaged by the feet of back-seat passengers or shifting cargo in the trunk. Mount the amplifier so that it remains dry ­ never mount an amplifier outside the car or in the engine compartment. 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. Make sure the amplifier is mounted securely. Installation Warnings and Tips · Always wear protective eyewear when using tools. [. . . ] Connect a wire from the GND connector on the amplifier to the nearest bare-metal chassis component; scrape away the paint to ensure good conductivity. Next, connect a wire between the BATT terminal on the amplifier and the POS(+) terminal of the vehicle's battery. Pass the wire through a factory-installed grommet in the firewall, or install a grommet if a factory grommet is not available. Connect a wire between the REM terminal of the amplifier and the "remote out" or powerantenna lead on the vehicle's radio. INDUCTOR 6dB/oct. LP (4-ohm) 8. 0mH 6. 4mH 5. 0mH 4. 2mH 3. 6mH 3. 2mH CAPACITOR 6dB/oct. HP (4-ohm) 530µF 400µF 318µF 265µF 227µF 198µF Wiring the Speaker-Output Connections P80. 2, P180. 2, P80. 4 All the Power Series amplifiers will accept up to 8-gauge speaker wire. Connect the speakers, observing proper polarity, to the speaker-output connector. The total impedance of the speaker system connected to the amplifier when the amplifier is driven in stereo must be at least two ohms. If you are bridging the amplifier, connect the speaker wires to the terminals marked "bridged, observing proper " polarity. The total impedance of the speaker system connected to the amplifier must be at least four ohms in bridged mode. 75Hz 100Hz 125Hz 150Hz 175Hz 200Hz If you are running the amp in Tri-Mode (stereo and mono simultaneously), connect the satellite speakers to the speaker connector as you would a pair of stereo speakers. Connect the subwoofer to the terminals marked "bridged" Refer to the chart above to determine the capacitor and inductor values you'll need to route bass signals to the woofer, and the midrange and high frequencies to the satellite speakers. These passive crossover components will also ensure that the impedance of the speaker system doesn't drop below two ohms. BP150. 1, BP300. 1, BP600. 1, BP1200. 1 Connect the woofers to the amplifier, observing proper polarity. Although these amplifiers have a single channel, duplicate positive and negative connectors are provided to facilitate the connection of multiple woofers. The total impedance of the speaker system connected to a BP Series amplifier must be at least 1 ohm. 4 Wiring the Input-Signal Connections Connect a pair of signal cables with RCA-type ends between the connectors on the amplifier and the RCA-type signal connectors on the source unit. If your radio has only speaker-level outputs, you should connect them to the speaker-level input connectors, observing proper polarity. When using the speaker-level inputs, it is not necessary to connect a wire between the "remote" terminal of the amplifier and the "remote" lead from the source unit. The speaker-level inputs will sense voltage on the speaker outputs and turn the amplifier on automatically. If you are installing a P80. 4 amplifier and your source unit has only one pair of RCA-type output connectors and a pair of speaker-level outputs, you may connect the RCA outputs to a pair of amplifier input channels (front or rear), and the speaker-level outputs to the other pair of amplifier input channels. Setting Input Level The BP150. 1, BP300. 1, BP600. 1 and BP1200. 1 are designed to provide constant bass regardless of the position of the source unit's front-to-rear fader position. Use of this feature requires that all four inputs are connected to the source unit as labeled on the amplifier (front, rear, right and left). If your source unit has only one pair of RCA-type output connectors and a pair of speaker-level outputs, you may connect the RCA outputs to a pair of amplifier input channels (front or rear), and the speaker level outputs to the other pair of amplifier input channels. [. . . ] It will only decrease the amount of volumecontrol rotation before the amp is at fulloutput power. It will also increase the amount of extraneous noise present in your system. 5 Troubleshooting Symptom No Audio (Red LED flashes every four seconds) Likely Cause Short circuit in speaker or speaker wire. Solution Disconnect speaker leads one at a time to determine which speaker or wire is shorted or defective. Repair the short circuit or replace bad speaker. [. . . ]
