With 450W RMS per channel at 2 ohms, 300W RMS at 4 ohms, and 900W x2 in bridge mode at 4 ohms, you have complete flexibility to power demanding speakers or combine channels for even more power.\u003c\/p\u003e\n\n\u003cp\u003eThe wide frequency range of 20 Hz to 20 kHz ensures that the amplifier handles everything from deep bass to crystal-clear highs with precision. With a signal-to-noise ratio of 95 dB, you get clean sound free from parasitic noise, while the low THD of 0.3% guarantees pure sound even at high volume levels.\u003c\/p\u003e\n\n\u003cp\u003eWhat sets the RS-SD300.4D apart is its exceptional combination of a 95 dB SNR (among the best in its range) and a THD of only 0.3%. This dual performance ensures sound reproduction of exceptional purity and fidelity, even in the most demanding environments. The Class D architecture ensures maximum efficiency, reducing power consumption and heat dissipation.\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e4-channel Class D architecture for maximum efficiency and low consumption\u003c\/li\u003e\n\n\u003cli\u003e95 dB SNR for crystal-clear sound without background noise\u003c\/li\u003e\n\n\u003cli\u003e0.3% THD for faithful music reproduction\u003c\/li\u003e\n\n\u003cli\u003eHigh power per channel for demanding speakers\u003c\/li\u003e\n\n\u003cli\u003eBridge mode to power subwoofers up to 900W\u003c\/li\u003e\n\n\u003cli\u003eIdeal for high-end full systems and SQ competition\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable border=\"1\" cellpadding=\"8\" cellspacing=\"0\" style=\"width:100%; border-collapse:collapse;\"\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eNumber of Channels\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e4 Channels\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eAmplifier Class\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003eClass D\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eRMS Power @ 2Ω\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e450 W x 4\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eRMS Power @ 4Ω\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e300 W x 4\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eRMS Bridge Power @ 4Ω\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e900 W x 2\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eFrequency Range\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e20 Hz - 20 kHz\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eSignal-to-Noise Ratio (SNR)\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e95 dB\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eHarmonic Distortion (THD)\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e0.3%\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eDimensions (L x D x H)\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e284.2 x 174 x 48 mm\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eManufacturer SKU\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003eRS-SD300.4D\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\u003ctr\u003e\n\n\u003ctd\u003e\u003cstrong\u003eEAN\/GTIN Code\u003c\/strong\u003e\u003c\/td\u003e\n\n\u003ctd\u003e8698814088851\u003c\/td\u003e\n\n\n\u003c\/tr\u003e\n\n\n\u003c\/table\u003e\n\n\u003ch3\u003eWhy Choose It\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eSolid power of 450W per channel for high-performance speakers\u003c\/li\u003e\n\n\u003cli\u003eExceptional 95 dB SNR for maximum sound purity\u003c\/li\u003e\n\n\u003cli\u003eUltra-low THD (0.3%) for exceptional musical fidelity\u003c\/li\u003e\n\n\u003cli\u003eBridge mode (900W x2) to power powerful subwoofers\u003c\/li\u003e\n\n\u003cli\u003eFull frequency range (20Hz-20kHz) for complete reproduction\u003c\/li\u003e\n\n\u003cli\u003eEfficient Class D architecture for low consumption and reduced heat\u003c\/li\u003e\n\n\u003cli\u003ePerfect combination of power, clarity, and efficiency\u003c\/li\u003e\n\n\u003cli\u003eIdeal choice for versatile and reliable audiophile installations\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003cp style=\"color:red; font-weight:bold;\"\u003e⚠️ IMPORTANT - INSTALLATION: It is IMPERATIVE to connect this amplifier at the impedance recommended by the manufacturer and to use the recommended wire gauge. For amplifiers over 2000W RMS, the vehicle's original battery is no longer sufficient. It is strongly advised to adapt the power supply (additional battery, reinforced alternator) to the amplifier's consumption to avoid any risk of damage and ensure optimal performance. ATTENTION: Any voltage drop below 12V can damage the product.\u003c\/p\u003e","brand":"Reiss Audio","offers":[{"title":"Default Title","offer_id":54268542746947,"sku":"RS-SD300-4D","price":349.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0890\/6247\/4051\/files\/RS-SD300.4D_1.webp?v=1773319749","url":"https:\/\/soundautoconcept.com\/en-eu\/products\/reiss-rs-sd300-4d","provider":"Sound Auto Concept","version":"1.0","type":"link"}
