The SP 4.900 uses Hertz's high-efficiency ADC (Advanced D-Class) amp technology to pump out four channels of 160 watts RMS each — driving your high-performance speakers and components to new heights of impact and enjoyment. You can also set up an SP 4.900 to play a stereo front-stage with plenty of volume while powering a subwoofer with up to 500 watts RMS from bridged channels — a great way to power a complete system with just this one amp. A variable bass boost fine-tunes your sub's thump when the amp's set up this way.\u003c\/p\u003e \u003ch4\u003eFits in and integrates well\u003c\/h4\u003e \u003cp\u003eNot only is the amp incredibly small and will fit just about anywhere, it carries an IP55 dust- and water-protection rating, so it'll work well in motorcycle, marine, and powersports applications as well as in a car. The amp's power, input, and output harnesses are sealed and the internal circuits are conformal-coated to ensure safe operation and protection from corrosion. Hertz's Universal Speakers Simulator (USS) technology works with a factory receiver's speaker load detection circuit to prevent shutdowns and to let it continue working when the amp uses the radio's speaker output wiring for its inputs.\u003c\/p\u003e \u003cdiv class=\"containerImageCaptionLarge marginZeroAuto\"\u003e\n\u003cimg style=\"display: block; margin-left: auto; margin-right: auto;\" src=\"https:\/\/images.crutchfieldonline.com\/ImageHandler\/scale\/646\/646\/products\/2023\/25\/301\/x301SP4900-o_other1.jpg\" alt=\"Hertz SP 4.900\" width=\"100%\"\u003e \u003cp style=\"text-align: center;\"\u003e\u003cem\u003e\u003cstrong\u003eSP 4.900 controls (protective cover removed)\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e \u003c\/div\u003e \u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan style=\"font-size: 12pt;\"\u003e\u003cstrong\u003eProduct Features\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eClass D 2 ohms Stable 4-Channel-Channel Amplifier\u003c\/li\u003e \u003cli\u003eRMS Power Rating:\u003c\/li\u003e \u003cul\u003e \u003cli\u003e4 ohms: 160 watts x 4 channel\u003c\/li\u003e \u003cli\u003e2 ohms: 250 watts x 4 channel\u003c\/li\u003e \u003cli\u003eBridged, 4 ohms: 500 watts x 2 channel\u003c\/li\u003e \u003c\/ul\u003e \u003cli\u003eTotal power output: 900 watts\u003c\/li\u003e \u003cli\u003eCEA-2006 Compliant Amplifier\u003c\/li\u003e \u003cli\u003eUltra-compact size\u003c\/li\u003e \u003cli\u003eIP55 dust- and water-protection rating\u003c\/li\u003e \u003cli\u003ePulse Width Modulated MOSFET power supply\u003c\/li\u003e \u003cli\u003eLED Power\/Protect Light\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\u003eBass gain\/level remote included\u003c\/li\u003e \u003cli\u003eInput sensitivity:\u003c\/li\u003e \u003cul\u003e \u003cli\u003eLow level: 6mV - 0.6V volts\u003c\/li\u003e \u003cli\u003eHigh level: 22mV - 2.2 volts\u003c\/li\u003e \u003c\/ul\u003e \u003cli\u003eFrequency Response: 10 - 35000 Hz\u003c\/li\u003e \u003cli\u003eTotal Harmonic Distortion (THD): 1%\u003c\/li\u003e \u003cli\u003eSignal to Noise Ratio: 105 dB\u003c\/li\u003e \u003cli\u003eVariable high-pass filter: 50 - 5000 Hz, 12 dB\/octave\u003c\/li\u003e \u003cli\u003eVariable low-pass filter: 50 - 5000 Hz, 12 dB\/octave\u003c\/li\u003e \u003cli\u003eVariable Bass Boost: 0 - 8 dB bass boost at 45 Hz\u003c\/li\u003e \u003cli\u003eFuse Rating: 50A\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003e\u003cspan style=\"color: #ff6600;\"\u003e\u003ca style=\"color: #ff6600;\" href=\"https:\/\/audiovisualworld.co.uk\/installation-accessories\/amp-wiring-kits.html?cat=1399_4-awg-4-gauge\" target=\"_blank\" rel=\"noopener\"\u003e4 AWG gauge power and ground wiring is recommended for installation\u003c\/a\u003e.\u003c\/span\u003e\u003c\/strong\u003e\u003c\/li\u003e \u003cli\u003eDimensions: \u003cstrong\u003eW\u003c\/strong\u003e x \u003cstrong\u003eL\u003c\/strong\u003e x \u003cstrong\u003eH\u003c\/strong\u003e\n\u003c\/li\u003e \u003cli\u003eUK Internet Dealer\u003c\/li\u003e \u003cli\u003eManufacturer's Warranty\u003c\/li\u003e \u003c\/ul\u003e \u003ch4\u003eWhat's in the box:\u003c\/h4\u003e \u003cdiv\u003e \u003cul\u003e \u003cli\u003e4-Channel amplifier with attached 8\" input\/output \u0026amp; power\/ground harnesses\u003c\/li\u003e \u003cli\u003e16\" Speaker output harness\u003c\/li\u003e \u003cli\u003e16\" Power \u0026amp; ground harness\u003c\/li\u003e \u003cli\u003e4 Speaker to RCA adapters\u003c\/li\u003e \u003cli\u003eFour 1\" screws\u003c\/li\u003e \u003cli\u003eUser manual\u003c\/li\u003e \u003c\/ul\u003e \u003c\/div\u003e","brand":"Hertz","offers":[{"title":"Default Title","offer_id":52761247875338,"sku":"SP 4.900","price":474.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0930\/4578\/4842\/files\/sp4900-1_1.jpg?v=1774294234","url":"https:\/\/audiovisualworld.co.uk\/products\/hertz-sp-4-900-900w-rms-spl-show-series-class-d-4-channel-amplifier","provider":"Audio Visual World","version":"1.0","type":"link"}
