® A400HLX, A600HLX Features A400HLX/A600HLX 4-channel amplifiers include: • Easy access top mounted controls • Continuously variable high pass/low pass crossover • 40Hz – 400Hz crossover frequency range • Crossover mode selector switch • Continuously variable bass boost, centered at 45Hz • Input level control • Remote level control (A600HLX) • Traditional input circuitry – low and high level inputs • Pre-amp output for installation flexibility • Dual status LED diagnostic indicator • Thermal, short circu
® A400HLX, A600HLX Location and Mounting The A400HLX/A600HLX amplifier’s compact design allows greater flexibility in mounting. It can be mounted under a seat or in the trunk. When selecting a location, remember that amplifiers generate heat. Select a location where air can circulate around the amplifier. Do not cover the amplifier with carpets or enclose it behind interior trim panels. Do not mount the amplifier in an inverted or upside down configuration.

® A400HLX, A600HLX 2CH / 3CH / 4CH 2 Channel (A400HLX) The A400HLX/A600HLX can be configured for three different input modes: 4 channel, 3 channel or 2 channel. 2CH 3CH 4CH When the input selector is set to 2CH, the amplifier is configured for bridged stereo operation. The amplifier will need a two channel input even though there are four inputs.
® A400HLX, A600HLX Level Bass BASS LEVEL The input level control matches the output of your radio to the input of the amplifier. After the installation is LEVEL complete, make sure the input level control on the amp is turned down all the way (counterclockwise or all the way to the left). Play a tape or CD (make sure bass and treble settings or EQ are flat too) and turn the volume up slowly until you just start to hear distortion. Now back the volume down just a bit.
® A400HLX, A600HLX Troubleshooting Problem Possible Cause Corrective Action Amplifier does not operate (power LED not on) when vehicle and radio are on No power to +12V terminal Repair wire or connections. No power to remote wire with radio on Check connections to radio with test light. Fuse blown Check fuse. Radio volume needs to be turned up too high for amp to work Input level control adjusted too low Adjust input level control.
