If it fails to illuminate, check the power connections to the amplifier and fuses. - PROT (Protection) : The amplifier protection circuitry will disable the amplifier if input 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, 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. 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 1-8 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. 18 Wiring Diagrams A2002V / A4002V / A8002V MONO MODE BRIDGED L R SUBWOOFER 4~8 OHM STEREO MODE L BRIDGED R LEFT SPEAKER 2~8 OHM RIGHT SPEAKER 2~8 OHM TRI MODE BRIDGED L R BRIDGED 4~8 OHM LEFT SPEAKER 4~8 OHM RIGHT SPEAKER 4~8 OHM : INDUCT LOW P OR ASS FILT ER : CAP ACIT HIGH P OR ASS FILT ER 19 Wiring Diagrams A4004V / A6004V 2 CHANNEL MODE BRIDGED 4~8 OHM CH1 BRIDGED CH2 CH3 BRIDGED CH4 BRIDGED 4~8 OHM CH1 CH2 CH3 CH4 3 CHANNEL MODE CH1 BRIDGED CH2 CH3 BRIDGED CH4 BRIDGED 4~8 OHM CH1 SPEAKER 2~8 OHM CH1 CH2 CH3 CH4 CH2 SPEAKER 2~8 OHM 4 CHANNEL MODE CH1 CH2 CH3 BRIDGED BRIDGED CH4 CH1 SPEAKER 2~8 OHM CH2 SPEAKER 2~8 OHM CH3 SPEAKER 2~8 OHM CH4 SPEAKER 2~8 OHM CH1 CH2 CH3 CH4 20 Wiring Diagrams A4004V / A6004V 6 CHANNEL MODE BRIDGED 4~8 OHM CH2 SPEAKER 4~8 OHM CH1 SPEAKER 4~8 OHM CH1 CH2 CH3 CH4 BRIDGED 4~8 OHM CH3 SPEAKER 4~8 OHM CH1 BRIDGED CH2 CH3 BRIDGED CH4 CH4 SPEAKER 4~8 OHM : INDUCT LOW P OR ASS FILT ER : CAP ACIT HIGH P OR ASS FILT ER COMPONENT VALUES FOR 6 dB PASSIVE CROSSOVER FREQUENCY 80Hz 100Hz 120Hz 150Hz INDUCTOR 7.5 mH 6.5 mH 5.5 mH 4mH CAPASITOR 470uF 330uF 330uF 220uF A8000V / A16000V MONO MODE SPEAKER SUB WOOFER 2~8 OHM 21 Adjusting and Tunning 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 20 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 amplifier temporarily shuts down if it gets too hot, then restarts automatically once it cools. ADJUSTING THE AUDIO LEVEL For the best performance, you must set GAIN (8V/0.2V) on the side of the amplifier to adjust match the level of the audio signals that enter the amplifier from the source unit. Use a screwdriver to turn GAIN (8V/0.2V) fully counterclockwise to 8V . Turn the auto sound system's volume control to about one-third of its full range. Adjust GAIN (8V/0.2V) to a comfortable listening level. Turn up the auto sound system's volume control until the sound begins to distort. Then immediately turn the volume down to a point just before where the distortion began. Caution Never turn up the auto sound system's volume control more than needed to adjust the audio level (More than two thirds of its maximum volume). 5. Adjust GAIN (8V/ 0.2V) until the sound is at the maximum level you want the amplifier to produce. 6. Adjust the auto sound system's volume control to a comfortable listening level. + 20dB + 10dB RESPONSE (dB) 0dB - 10dB - 20dB - 30dB FREQUENCY RESPONSE 1. 2. 3. 4.

( NO ) CURE Check fuses in amplifier. Be sure Turn-on lead is connected Check signal leads. Check gain control. Check Tuner/Deck volume level. Clean contacts on fuse holders. Check for speaker short or Amplifier overheating. Repair power wire or connections. Check connections to radio. Replace fuse. Inspect for short circuit or an open connection. Reverse Left and Right RCA inputs to determine if it is occurring before the amp. Be sure proper speaker load impedance recommendations are observed. (If you use an ohmmeter to check speaker resistance, please remember that DC resistance and AC impedance may not be the same.) Turn radio down Separate speaker wires and insulate Is the Diagnostic LED illuminated ? ( YES ) AMP NOT SWITCHING ON No power to power wire No power to remote wire with receiver on Fuse broken NO SOUND IN ONE CHANNEL Check Speaker Leads Check Audio Leads AMP TURNING OFF MEDIUM/HIGH VOLUME Check speaker load impedance STATUS LAMP ON Temperature shut down Speaker wires short 23 Warning / Disclaimer WARNING Investigate the layout of your automobile thoroughly before drilling or cutting any holes. Take care when you work near gas tanks, gas lines, hydraulic lines, and electrical wiring. Do not use the power amplifier unmounted. Attach the system securely to the automobile to prevent damage, particularly in the event of an accident. Do not mount the system so that the wire connections are unprotected or are subject to pinching or damage from nearby objects. The +12V DC power wire must be fused at the battery positive terminal connection. Before making or breaking power connections at the system power terminals, disconnect the +12V wire at the battery end. Confirm your radio/head unit and/or other equiptment is turned off while connecting the input jacks and speaker terminals. 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 a different type or rating may result in damage to this system which is not covered by the warranty. Disclaimer Specifications are subject to change with out notice.
