This innovative system has been designed a 12 volts DC negative ground power supply. Easy installation with mounting hardware is provided. The PLMRA 400 has two input levels. The high or low impedance input can be connected to units which incorporate BTL circuity or common-ground types.

If Your car stereo has four speaker outputs (LF,RF,LR,RR). Wire input as per FIG. 3 & FIG 3A. If your car stereo has two speaker outputs, please wire as per FIG 4 & FIG 4A. 4.HIGH IMPEDANCE INPUT (LOW LEVEL INPUT) This unit is provided with gold plated RCA input jacks for high impedance. Couple the RCA input with the car stereo output using RCA type connector cables. If your stereo has only left and right 2 channels outputs. You must use a Y-adaptor for connection (FIG 2). 5.POWER FUSE Power fuse protects both this amplifier and the automobile electrical system from wrong electrical conditions. 6.POWER SUPPLY TERMINAL Connct the +12V DC power supply wire into this terminal.

B.GROUND Ground terminal connects the ground wire from the chassis of the automobile. C.REMOTE Remote terminal connects the control wire which provides remote turn-on and off of the amplifier by the RADIO/CASSETTE players power antenna wire. 7.SPEAKERS TERMINALS Speakers can be easily connected to signal barrier strip. You may use 4 to 8 ohms speakers. Before connecting, please check speaker connection diagrams. 2 ELECTRICAL & AUDIO CONNECTIONS A.

B. SPEAKER CONNECTION Connect the speaker output terminals to the corresponding speakers. (Figure 5) The speakers must be high quality and capable of handling high power. Separated return paths and strong wires are required. (Fig. 5) NOTE: This amplifier has built-in short circuit protection. If you mistakingly connect any speaker wires to ground, or positive power (+) and (-) Wires short together, the protection circuit will operate automatically and cut-off output. In case of this, you must switch OFF the whole system immediately double check speaker wire connections and isolation before switching on the amplifier again. 5 ELECTRICAL & AUDIO CONNECTIONS C.
