Hertz's high-efficiency Advanced D-Class (ADC) amp technology pumps out four channels of 90 watts RMS each — driving your high-performance speakers and components to new heights of impact and enjoyment. You can also set up an SP 4.500 to play a pair of front speakers while also powering a subwoofer with up to 300 watts RMS — a great way to power a complete system. A variable bass boost helps fine-tune 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, but it also carries an IP55 dust- and water-protection rating, so it'll work well in motorcycle, marine, and powersports applications. The amp's power, input, and output harnesses are sealed and the internal circuits conformal-coated to ensure safe operation and protection from corrosion. Hertz's Universal Speakers Simulator (USS) technology works with your factory receiver's speaker load detection circuit to prevent shutdowns when you use the radio's speaker wiring for the amp's input signal.\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\u003e90 watts RMS x 4 at 4 ohms\u003c\/li\u003e\n\u003cli\u003e150 watts RMS x 4 at 2 ohms\u003c\/li\u003e\n\u003cli\u003e300 watts RMS x 2 bridged at 4 ohms,\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eCEA-2006 compliant: 75 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\u003e8-gauge power and ground leads and a 25A fuse recommended\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003edimensions: 8.85\"W x 1.94\"H x 5.15\"D\u003c\/li\u003e\n\u003cli\u003ewarranty: 1 year\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eMFR # SP 4.500\u003c\/li\u003e\n\u003cli\u003eItem # 301SP4500\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":40535616782400,"sku":null,"price":599.99,"currency_code":"USD","in_stock":false},{"title":"Installed","offer_id":40535616815168,"sku":null,"price":799.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0583\/7943\/6096\/files\/download_13_76b639bf-4dbc-4d16-aa02-0c3cc6db0a77.png?v=1740745415","url":"https:\/\/rallysounds.com\/products\/sp4-500","provider":"Rally Sounds","version":"1.0","type":"link"}
