Kicker 42PXA5001 Compact Mono Amplifier

Features:

• Power Output: The PXA500.1 is a mono amplifier designed to output 250 watts RMS at 4Ω (<1% THD+N) and 500 watts RMS at 2Ω (< 1% THD+N).
• Controls: The controls for the amplifier include a rotary gain control and five DIP switches. The DIP switches, located on the bottom of the amp under a rubber cover, can select the following - Low Pass Crossover, Bass Boost, Input Level, Auto Turn-On.
• Input Signal: The PXA500.1 is capable of receiving either high- or low-level input signals, and you can select the input type on the bottom of the amp.
• Differential Audio: The differential audio circuit reduces the likelihood of picking up any engine noise, and helps lower THD (Total Harmonic Distortion).
• Weather Resistant: The PXA Amps are weather-resistant, using a conformal-coated circuit board for protection against the elements. They also include no-rust stainless-steel mounting hardware.
• Power Wiring: The amp comes with a power and ground terminal adapter that will accept up to 8-gauge wire. Power and ground wire (8-gauge is recommended) can be inserted into the adapter and tightened with a flat or Phillips head screwdriver. The adapter then plugs directly into the amplifier. An in-line fuse holder with a 40A MAXI fuse is included with the amp. No other power or ground wiring is included.
• Speaker Output/Turn-on Lead: The speaker output wires and the amp turn-on lead are located on the same plug-in harness. Two pairs of 16-gauge wire are soldered together to form a single positive and a single negative speaker output. The blue turn-on lead should be connected to the amp remote wire on the aftermarket head unit's harness. If you are connecting the amp to a head unit via the speaker-level input, it is not necessary to connect the turn-on lead, as the amplifier with turn itself on when the amp detects a 6V DC signal on the input. You will need to select the proper Auto Turn-On on DIP switch #5 on the bottom of the amp.
• Optional CXARC Remote: You can control the output level of the amplifier remotely with the optional CXARC Remote Bass Control. The remote plugs into the 3.5mm mini jack on the end of the amplifier. The CXARC comes with a 19.75' cable that allows you to locate the controls near the driver's location.
• Subsonic Filter: The PXA500.1 includes a 24 dB/octave subsonic filter, fixed at 25 Hz. This filter eliminates power-robbing, extremely-low frequencies that most speakers cannot reproduce.
