B+ Terminal (Battery Positive) POWER GND REM BAT T A6005DN A8005DN A12005DN Due to the power requirements of the amplifier, this connection should be made directly to the positive (+) terminal of the battery. For a safety measure, install an in-line fuse holder (not included) as close to the battery positive (+) as possible with an ampere rating not to exceed the total value of fuses in the amp. 5. Input Sensitivity Adjustment MIN MAX A6005DN A8005DN A12005DN This control adjusts the amplifier's sensitivity. Input sensitivity is variable from 200 Millivolts to 4 volts. Clockwise increases sensitivity. Counterclockwise decreases sensitivity. THE KNOB IS NOT A VOLUME CONTROL. A lower signal level will require increased sensitivity for full power. A higher signal will require decreased sensitivity.

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 shut down due to a thermal overload condition, please allow it 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. 10 Controls and Functions Control and Functions Fig 1.

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. Are your components matched? The RMS power rating of your speakers must be equal or greater than the amplifier's. They also must be 2-8 Ohms impedance (this information is normally printed on the speaker magnet). c. Consider both the length of your leads, and routing when determining the mounting location. Pre-Amp input Jacks require a length of high quality shielded male to male RCA patch cord. Mounting Your System The mounting position of your amplifier will have a great effect on its ability to dissipate the heat generated during normal operation. It has an ample heat sink for heat dissipation, and also is designed with a thermal shut-down (for heat protection) circuit, having enough air directed over the cooling fins will improve heat dissipation dramatically. DO NOT enclose the amplifier in a small box or cover it so that air can not flow around the fins. Temperatures in car trunks have been measured as high as (155 F) in the summer time. Since the thermal shut-down point for the amplifier is (158 F) it is easy to see that it must be mounted for maximum cooling capability. To achieve the maximum advantage of convection air flow in an enclosed trunk, mount the amplifier in a horizontal position. Cooling requirements are considerably relaxed when mounting inside the passenger compartment since the driver will not allow temperatures to reach a critical point. Floor mounting under the seat is usually satisfactory as long as there is at least 1 inch (2.54 cm) above the amplifier's fins for ventilation. a. Select a suitable location that is convenient for mounting, accessible for wiring, and has ample room for air circulation and cooling. b. Use the amplifier as a template to mark the mounting holes. Remove the amplifier and drill holes. Use extreme caution. Inspect underneath the surfaces before drilling! c. Secure the amplifier using the screws provided. CAUTION: Before connecting any wires to the amplifier, disconnect the ground lead from the battery. Leave the ground lead disconnected until you are done wiring the amplifier. 13 Wiring Diagrams A6005DN A8005DN A12005DN MONO MODE SUBWOOFER 2~8OHM : INDUCTOR LOW PASS FILTER : CAPACITOR HIGH PASS FILTER 14 Adjusting and Tuning TURNING ON THE AMPLIFIER The amplifier automatically turns on a few seconds after you turn your vehicle's ignition switch to ACC or turn on your auto sound system (depending on how you have wired the system). The POWER indicator on the top of the amplifier illuminates when the amplifier is on. Important: Your amplifier requires 30 amps or more of power from your vehicle's battery during operation. To protect your battery from discharging, do not operate the amplifier unless your vehicle is running. Note: Your a ...
