PRECAUTIONS ● This unit is designed for negative ground 12 Volts DC operation only. ● Use speakers with an impedance of 2Ω or 4Ω (4Ω to 8Ω when used as bridged amplifier) ● Avoid installing the unit where: – It would be subject to high temperatures, such as from direct sunlight or hot air from the heater. – It would be exposed to rain or moisture. – It would be subject to dust or dirt.
WIRING INSTRUCTIONS POWER CONNECTION The battery terminal (BATT) must be connected directly to the positive terminal of the vehicle battery to provide an adequate voltage source and minimize noise. Connecting the battery terminal lead to any other point (such as the fuse block) will reduce the power output and may cause noise and distortion. Use only #4 gauge or thicker (smaller gauge#) wire for this lead and connect it to the terminal of the battery after all other wiring is completed.
POWER CONNECTION LEADS HEAD UNIT FUSE (+12V) SENS OUT POWER BATTERY DC 12V To a metal part of car NOTES ON THE POWER SUPPLY: ● Connect the +12V power input lead only after all other leads have been connected. ● Be sure to connect the ground wire of the unit securely to a metal part of the car. ● A lose connection may cause a malfunction of the amplifier. ● REM: The unit is turned on by applying +12 Volts to this terminal.
OPERATION GAIN = INPUT LEVEL CONTROL ● The input level control allows the system to work well within a wide range of output level. Choose the adjustment in the way that you achieve a sound most possibly without any distortion. As a guideline the following procedure is recommended: –If you use several amplifiers, the adjustment has to be made for each set separately. Tune in the volume of your car radio to 2/3 of the maximum volume.
HOW TO PROCEED IN CASE OF FAULTS No Function: ● The connection cable is not connected correctly (=terminal +12V/GND/REM). Ensure that all connections and mechanic contact and that the jacket has been removed. The fuse is defective-pay attention to the correct value of a new fuse! No Sound : ● Speaker cable or speaker plug are not connected correctly. No Sound / Red LED Protection is on: ● The plus and minus wires of the speaker cable have contact, thus eliminate the short circuit.
