[. . . ] QUALITY, RELIABILITY, & PURE BLISS 4000 WATT RMS CLASS D COMPETITION AMP A4KDN OPERATING INTSTRUCTIONS PLEASE RETAIN MANUAL FOR FUTRE USE AND REFERENCE The Audiobahn Way To bring the product to market that excites the consumer through sound and vision from an orientation of integrity and customer service. We strive to take car audio to an extreme the world has never seen, and a world that never stops evolving. Audiobahn was established in 1997 with one long-term goal in mind, "Build it Bigger, Badder, & Better, and the people will take notice!" We back this statement with an engineering team that has brought home several Innovations, Design & Engineering Showcase Awards, and a marketing team from around the world that spends countless hours developing our no compromise products to satisfy the most discriminating enthusiasts. Our global manufacturing facilities feature ISO9002 ratings (the highest level of quality control awarded in the electronics manufacturing industry), fully robotic assembly lines and a state of the art, California based R & D laboratory. [. . . ] Clipping can be caused by low voltage supply to the amplifier, having the gain / level or bass boost setting adjusted to high, or too low of a ohm load causing the amplifier to overdrive itself. Speaker Terminals These terminals are used to wire your subwoofer(s) to the amplifier. 11. B- Terminal (Chassis Ground) To avoid unwanted ignition noise caused by ground loops, it is essential that the amplifier be grounded to a clean, bare, metal of the vehicle's chassis. This metal surface should be solid, strong and connected directly to the frame of the car. Note: GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FEET (1 METER) 12. B+ Terminal (Battery Positive) Due to the power requirements of the amplifier, this connection should be made directly to the positive (+) terminal of the battery. For safety purposes, install an in-line fuse holder (not included) as close to the battery positive (+) terminal as possible with an ampere rating not to exceed the total value of fuses in the amplifier. Controls and Functions 13. Remote Turn-on Input The remote terminal needs to be wired to the car's stereo or source unit remote turn on wire. This amplifier is turned on remotely when the vehicle's stereo is turned on. NOTE: iF YOUR RADIO DOES NOT HAVE A +12 VOLT OUTPUT LEAD WHEN THE CAR IS TURNED ON, THE "REMOTE" TERMINAL ON THE AMPLIFIER CAN BE CONNECTED TO THE VEHICLE'S ACCESSORY CIRCUIT THAT IS LIVE WHEN THE KEY IS TURNED ON. 14. LED Indicators PWR (Power): This BLUE LED will illuminate when the amplifier is turned on. If it fails to illuminate, check the fuses and power connections to the amplifier. PROT (Protection): The amplifier protection circuitry will disable the amplifier if there is an imput overload, short circuit, or extremely high temperature conditions are detected. When the protection mode is in operation, the LED indicator on the side panel will be illuminated RED, indicating the amplifier has gone into a self-preservation mode. If you observe that the protection LED is lit, please check the system carefully to determine what has caused the protection circuit to engage. The amplifier can be reset by turning the remote power off and then on again. If the amplifier shut down due to a thermal overload condition, please allow time for the amp to cool down before restarting. If the amplifier shut down because of an input overload or short circuit, be sure to repair these conditions before attempting to power up the amplifier again. Planning and Mounting Your System Planning Your System Before beginning the installation, consider the following: a. If you plan to expand your system by adding other components sometime in the future, ensure that adequate space is left, and cooling requirements are met. If your radio/source is equipped with Pre-Amp outputs, it is possible to utilize them to drive an Amplifier and connecting (amplifier) to the 2 rear speakers. Then, use the built-in power of your radio to drive the 2 front speakers. NOTE: DISTORTION LEVEL IS CONSIDERABLY LOWER FROM PRE-AMP (LOW LEVEL) OUTPUTS, THAN SPEAKER (HIGH LEVEL) OUTPUTS. b. [. . . ] If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the system. Using a fuse of different type or rating may result in damage to this system which is not covered by the warranty. Disclaimer Specifications are subject to change without notice.
