PLMRC400X4 4-Channel Weather-Resistant Audio Amplifier System Class D Compact Designed Suit for Car, ATV, UTV, 4X4, Jeep, Motorcycle and Marine, and any other Weather Resistant Application
INTRODUCTION This power amplifier has been designed to provide high quality performance with a minimum of maintenance. However, it's performance will only be as good as the care and quality of components with which is installed. We therefore advise that you read these instructions very carefully to familiarize yourself with the product and it's features. Before installing the power amplifier please read this instruction manual carefully.
PRECAUTIONS • This unit is designed for negative ground 12-14.50 VoIts (DC) operation only • Use speakers with an impedance of 2 or 4 Ohms (4 to 8 Ohm 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 #10 gauge or thicker (smaller gauge #) wire for this lead and connect it to the terminal of the battery after all other wiring is completed.

BRIDGED MODE POWER CONNECTION LEADS 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 amalfunction of the amplifier. 6 www.PyleUSA.
• REM: The unit is turned on by applying + 12 Volts to this terminal. This terminal does not draw heavy current like the tow Power Terminals so a thinner connecting wire is acceptable. Standard 20 GAUGE is fine and the standard color is blue. If the radio is equipped with a Power Antenna control wire, it can drive this terminal. If the Power Antenna wire is already in use, you can still splice into it. With this method, the unit will turn on automatically with the radio.
X-OVER FREQUENCY CONTROL A. When the crossover control is in the Low-Pass position, this control becomes active allowing you to select your crossover point. B. When the crossover control is in the High-Pass position, this control becomes active allowing you to select your crossover point. CROSS OVER SWITCH • Full: full range frequency. • Low pass: the lower frequency under setting point can be pass. • High pass: the higher frequency above setting point can be pass.
REM (ON/OFF) REMOTE CONTROL Connect the REM terminal to the automatic antenna connector of your car radio. Now when turning ON and OFF your car radio, the amplifier automatically switches ON and OFF. A cable diameter of 0.5 mm’ is sufficient. TROUBLESHOOTING No Function The connection cable is not connected correctly (=terminaI + I2V/GND/REM). Ensure that all connections and mechanic contact and that the jacket has been removed.
INTERFERENCE All cables can source and create interference. The power cable and Cinch/RCA audio cable are very prone to interference; the remote cables are less prone. There is often interference caused by the generator (piping), ignition (cracking) or other car electronic parts. Most of these problems can be eliminated by correct and careful cabling.
