• Pulse-Width Modulated (PWM) MOSFET power supply for maximum performance with minimal distortion. • Remote turn-on with "soft start" muting to prevent turn-on "thump". • Advanced circuitry design featuring bridgeable and mixed mode operation for use in various system configurations including 4, 3, or 2 channel systems. • Variable high-pass/low-pass electronic crossover with a 12dB per octave slope (adjustable range: 55Hz to 5.5kHz). • Variable bass boost circuit to reinforce low frequency signa

power source, audio signal input, gain control, etc.). 2. Install speaker box mounting brackets using provided screws □ (if needed). 3. Mount amplifier using provided screws. 4. □Connect the speaker wire from amplifier to speaker's box. 5. Connect the RCA to your processor or head unit RCA output. 6. Connect the ground cable from amplifier to a proper grounding □ connection on the vehicle chassis. 7. Connect the DC power to amplifier. 8. Adjust amplfier gain appropriately. A WARNING I

This will protect the wire from being nicked and causing a short circuit. ♦ Extra cable can cause signal loss and act as an “antenna” for noise. Use only high-quality RCA cables that are no longer than necessary to make a direct connection with the source unit or equalizer. ♦ Depending on the type of system being installed, refer to the examples in Figures 4 through 6 (starting on page 6) for information on wiring and setting the operation mode.

You’ve selected an amplifier that is one of the finest and most unique available on the market today. For 4-ohm loads, the APA5241 puts out 35 watts of continuous power on channels 1 through 4 and also delivers 100 watts of continuous power on channel 5. It also comes with the following features: ♦ Full frequency response with low distortion and exceptional signal-to-noise performance ♦ Advanced circuit design features bridgeable and mixed-mode operation for use in a variety of 5-, 4-, or 3-ch

If you hear any noise, static, distortion or no sound at all, check the connections and refer to Troubleshooting. Depending on your system, the volume may become quite loud even at low level settings. Until you get an “audio feel” for the system’s power, use care when adjusting the controls. 3. Turn the balance controls to their extreme positions and listen to the results. Audio output should match control settings (audio from the left speaker when balance is left). 4. Increase the volume and ve

The APA4203 puts out 50 watts of continuous power into a 4-ohm load and delivers 75 watts (typical) into a 2-ohm load. The APA4162 is rated at 40 watts of continuous power or 65 watts (typical) for the same loads. Both models come with the following features: ♦ Full frequency response with low distortion and exceptional signal-to-noise performance ♦ Advanced circuit design features bridgeable and mixed-mode operation for use in a variety of 4-, 3-, or 2-channel systems ♦ Independent front/re

CAUTION! Although Clarion amplifiers include heat sinks and protection circuits,mounting an amplifier in a tight space without any air movement will damage the unit’s internal circuitry over time. 8 apx2121_4241_1301.qxd 2/6/2008 11:57 AM Page 9 • Mount the amplifier on a rigid surface away from subwoofer enclosures or to any area that is prone to vibration. Do not install the amplifier on plastic or on any other combustible material. • For easy system setup, mount the amplifier so that the fron
