The SP 4.900 uses Hertz' 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\n\u003ch4\u003eFits in and integrates well\u003c\/h4\u003e\n\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 shut downs and to let it continue working when the amp uses the radio's speaker output wiring for its inputs.\u003c\/p\u003e\n\u003cdiv class=\"col-12 col-lg-7\"\u003e\n\u003cdiv id=\"hightlightWrapper\" class=\"keep-reading-wrapper open\"\u003e\n\u003cdiv class=\"highlight-wrapper\"\u003e\n\u003ch4\u003eProduct highlights:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e4-channel amplifier\n\u003cul\u003e\n\u003cli\u003e160 watts RMS x 4 at 4 ohms\u003c\/li\u003e\n\u003cli\u003e250 watts RMS x 4 at 2 ohms\u003c\/li\u003e\n\u003cli\u003e500 watts RMS x 2 bridged at 4 ohms,\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eCEA-2006 compliant: 145 watts RMS x 4 at 4 ohms , 1% THD+N, 14.4 volts\u003c\/li\u003e\n\u003cli\u003eHertz Advanced D-Class amp technology — frequency response: 10-35,000 Hz\u003c\/li\u003e\n\u003cli\u003evariable high- and low-pass filters (50-5,000 Hz, 12 dB\/octave)\u003c\/li\u003e\n\u003cli\u003evariable bass boost on Ch 3-4 (0-8 dB at 45 Hz)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch5\u003eMore Info:\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003eIP55 rated for dust- and water-protection\n\u003cul\u003e\n\u003cli\u003econformal-coated circuit boards, aluminum chassis, protective control cover\u003c\/li\u003e\n\u003cli\u003epower, input, and output wire harnesses sealed for protection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003epreamp and speaker-level inputs\n\u003cul\u003e\n\u003cli\u003eUSS circuit supplies load for receiver output to prevent shut-down\u003c\/li\u003e\n\u003cli\u003eRCA-to-wire adapters included\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003ewiring, fuse, and hardware not included with amplifier\n\u003cul\u003e\n\u003cli\u003e4-gauge power and ground leads and an 50A fuse recommended\u003c\/li\u003e\n\u003cli\u003epower and ground harness connections may require distribution blocks or additional wiring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003edimensions: 8.853\"W x 1.936\"H x 5.15\"D\u003c\/li\u003e\n\u003cli\u003ewarranty: 1 year\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMFR # SP 4.900\u003c\/li\u003e\n\u003cli\u003eItem # 301SP4900\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"col-12 col-lg-5 whats-in-the-box\"\u003e\n\u003cdiv class=\"whatsInTheBox sideBlock\"\u003e\n\u003ch4\u003eWhat's in the box:\u003c\/h4\u003e\n\u003cdiv\u003e\n\u003cul\u003e\n\u003cli\u003e4-Channel amplifier with attached 8\" input\/output \u0026amp; power\/ground harnesses\u003c\/li\u003e\n\u003cli\u003e16\" Speaker output harness\u003c\/li\u003e\n\u003cli\u003e16\" Power \u0026amp; ground harness\u003c\/li\u003e\n\u003cli\u003e4 Speaker to RCA adapters\u003c\/li\u003e\n\u003cli\u003eFour 1\" screws\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"My Store","offers":[{"title":"Un-Installed","offer_id":40535616880704,"sku":null,"price":799.99,"currency_code":"USD","in_stock":true},{"title":"Installed","offer_id":40535616913472,"sku":null,"price":999.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/7943\/6096\/files\/download_13_3c9227bc-fcf3-45f7-b9cd-16298390ba94.png?v=1740745413","url":"https:\/\/rallysounds.com\/products\/sp4-900","provider":"Rally Sounds","version":"1.0","type":"link"}
