This reliable and compact KXM Series rocker will run cool even when pushed hard, thanks to its high-mass heatsink, high-tech internal components, and efficient full-range Class-D amp technology. Building a big system piece-by-piece? You could start by using this amp in 2-channel mode to drive a couple of subs with 250 watts each, and then later switch the amp back to 4-channel mode to power your speakers when you get a bigger amp for the subs.\u003c\/p\u003e \u003ch3\u003eMade for marine use\u003c\/h3\u003e \u003cp\u003eThe KXMA500.4 features a conformal coated circuit board for improved water and dust resistance, plus corrosion-resistant power connections, a gasket-sealed front cover, and stainless steel mounting hardware that won't rust all over your boat's gel coat or carpeting.\u003c\/p\u003e \u003ch3\u003eConnection perfection\u003c\/h3\u003e \u003cp\u003eKicker employs their Fail-Safe Integration Technology (FIT2™) to reject noise and stop any interference generated by your boat's electronics, so you'll enjoy your music clean and pure. Speaker-level inputs make it possible to hook this amp up to almost any stereo receiver or radio. Kicker also helps you set this amp's gain properly, by offering free test tones for downloading. You play a tone and turn the gain up until the gain knob glows red. Then, you turn it down until it just goes out, and the amp's gain is set perfectly.\u003c\/p\u003e \u003ch3\u003eVersatile controls behind the folding door\u003c\/h3\u003e \u003cp\u003eA gasket-sealed front door gives you quick and easy access to your amp's controls. You can tune for almost any kind of speaker, as the steeply-sloped high- and low-pass filters offer a wide range of adjustments. The filter section for the Amp 2 channels can be set up for bandpass operation — where both the high- and low-pass filters are engaged to allow only the frequencies between them to play — for optimizing the signal for midrange speakers in a 3-way system.\u003c\/p\u003e \u003cdiv class=\"containerImageCaptionFull borderNone marginZeroAuto\"\u003e\n\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/images.crutchfieldonline.com\/ImageHandler\/scale\/978\/978\/products\/2021\/6\/206\/x20648KXM54-o_other5.jpg\" alt=\"Kicker 48KXMA500.4\" width=\"504\" height=\"113\"\u003e \u003cp style=\"text-align: center;\"\u003e\u003cem\u003e\u003cstrong\u003eKXMA500.4 control panel\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e \u003c\/div\u003e \u003cp\u003e\u003cstrong\u003e\u003cspan style=\"font-size: medium;\"\u003eProduct Features:\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eKicker KXM Series KXMA500.4 Marine Amplifier\u003c\/li\u003e \u003cli\u003eClass-D Full Range 2-Ohm Stable 4-Channel Amplifier\u003c\/li\u003e \u003cli\u003eRMS Power Rating:\u003c\/li\u003e \u003cli\u003e4 ohms: 50 watts x 4 chan.\u003c\/li\u003e \u003cli\u003e2 ohms: 100 watts x 4 chan.\u003c\/li\u003e \u003cli\u003e1 ohm: ------------\u003cstrong\u003eN\/A\u003c\/strong\u003e------------\u003c\/li\u003e \u003cli\u003eBridged, 4 ohms: 400 watts x 1 chan.\u003c\/li\u003e \u003cli\u003eTotal power output: 400 watts\u003c\/li\u003e \u003cli\u003eCEA-2006 Compliant Amplifier\u003c\/li\u003e \u003cli\u003eConformal coated circuit boards\u003c\/li\u003e \u003cli\u003eMarine compliant (ABYC\/NMMA) power terminals\u003c\/li\u003e \u003cli\u003eSettings protected behind the gasket-sealed door\u003c\/li\u003e \u003cli\u003eBlack anodized aluminum housing with teal LED\u003c\/li\u003e \u003cli\u003eFail-Safe Integration Technology\u003c\/li\u003e \u003cli\u003eSimplify the installation by picking up some Kicker KISL speaker-to-RCA cables\u003c\/li\u003e \u003cli\u003eLED power (green) and protect (red) indicators\u003c\/li\u003e \u003cli\u003eSoft start turn-on\u003c\/li\u003e \u003cli\u003e4\/3\/2 channel operation\u003c\/li\u003e \u003cli\u003eSpeaker-level (high-level) inputs\u003c\/li\u003e \u003cli\u003e3-way protection circuitry (thermal, overload, and speaker short protection)\u003c\/li\u003e \u003cli\u003eDual speaker terminals simplify the hookup of multiple speakers\u003c\/li\u003e \u003cli\u003eHeavy-duty aluminum alloy heat-sink\u003c\/li\u003e \u003cli\u003eInput sensitivity: 250mV-10V\u003c\/li\u003e \u003cli\u003eFrequency Response: 10 -
