Mount the amplifier in car You can mount the amplifier either under a seat or on the rear tray. Note •• To avoid interference, do not place the amplifier too close to the car audio or antenna. •• The supplied mounting screws are 25mm long. Make sure that the mounting board is thicker than 25mm. 1 Place the unit on the location for installation. 2 Mark the positions of the four screw holes. 3 Drill the holes with driller of approximately 4mm in diameter. 4 Mount the unit with the supplied screws. i POWER/PROTECTED • Light in green when the amplifier is switched on. • Light in red when the amplifier is abnormal and protected. j SPEAKER OUTPUT • Connect to speakers or subwoofers. k Fuse: 25A x 2 l POWER (GND/REM/+12V) • To connect +12V-DC power wire, ground wire, and remote control wire. EN 7 Connect car audio Connect the amplifier to the car audio with an RCA cable. Car audio unit Car audio unit LINE OUT LINE OUT Connect speakers Note Use speakers with an •• impedance of 2 to 8 ohm (4 to 8 ohm when used as a bridged amplifier). •• Match the “left”, “right”, “+” and “-” terminals correctly. Revised polarity may degrade sound quality. Option 1: Stereo mode: connect 4 speakers 4 ohm 4 ohm 4 ohm 4 ohm Option 2: Mono bridged mode: connect 2 speaker 4 ohm speaker 4 ohm speaker Option 3: Tri-mode: connect 6 speakers 4 ohm 4 ohm 4 ohm 4 ohm 8 ohm 8 ohm English EN 8 Connect power 1 Make the power connection as illustrated below: Connect the g • round wire from the car to the GND socket. • Connect the remote wire from the car audio to the REM socket. • With this connection, you can turn on/off the amplifier with the car audio. • Connect the power wire from the car battery to the +12V socket. Less than 450mm (18 in) Fuse (40A) +12V car battery Car audio unit Remote output To a metal point of the car Tip •• If your car audio does not have remote output, connect the remote input terminal (REM) to the accessory power supply. •• To avoid short circuit, cover the power socket with the supplied shield and screws after connected power wires. See below illustration: EN 9 Adjust bass boost To enjoy more bass sound: 1 Set HPF at OFF mode. 2 Slide BASS BOOST to 12dB position. Tip •• If BASS BOOST is set at 0dB position, no extra bass will be boosted. Note •• If HPF is set at 180Hz mode, the bass frequency will be filtered. About the protector indicator The amplifier has a built-in protection circuit to protect the transistors and speakers in following conditions: • The amplifier is overheated. • A DC current is generated in speakers. • The battery voltage is too low or too high. Or • The speaker terminals are short circuited. When the PROTECTED indicator lights up in red, the amplifier shuts down automatically. In this case please: 1 Take out the disc or tape and turn off the car audio. 2 Check the cause of the malfunction. 3 If the amplifier is overheated, let it cool down. 4 Use your power amplifier Select HPF/LPF mode 1 Slide LPF or HPF to the selected mode. HPF (highpass- filter) 80Hz More low frequency signal is filtered. Select this if you prefer less bass effect. OFF LPF (lowpass- filter) 180Hz More high frequency signal is filtered. Select this if you prefer stronger bass effect. OFF Adjust input level To ensure sound quality, adjust input level to match it with the car audio’s output voltage. 1 Check the line output voltage of the connected car audio. 2 Rotate INPUT LEVEL to select a matched voltage: 0.3V to 6V.

If the fuse gets damaged immediately after they are replaced, the amplifier might have internal malfunction. In such case, consult qualified personal for repair. EN 11 The unit becomes abnormally hot. Place the amplifier i •• n a well ventilated location. •• Use speakers with suitable impedance: 2-8 ohm (stereo), 4-8 ohm (bridged). 6 Troubleshooting To keep the warranty valid, never try to repair the system yourself. If you encounter problems when using this apparatus, check the following points before requesting service. If the problem remains unsolved, go to the Philips web site (When you contact Philips, ensure that the apparatus is nearby and the model number and serial number are available.
