However, modern Class D amplifiers have evolved, offering stable performance while maintaining maximum efficiency and low power tolerance. The ST4.1000D is designed to provide clean power that rivals traditional full-range amplifiers, while requiring minimal power consumption. This makes it perfect for car audio systems, motorcycles, boats, and off-road vehicles where space and efficiency are crucial.\u003c\/p\u003e\n\u003cp\u003eDespite its small size, the ST4.1000D delivers a substantial 1000W peak power output and stable RMS power for your audio setup. Whether you’re powering multiple speakers or a subwoofer, this amplifier has you covered. Its ultra-micro footprint allows for easy installation even in tight spaces without compromising on sound quality.\u003c\/p\u003e\n\u003cp\u003eThe Class D design ensures high power efficiency and prevents excessive heat build-up, allowing you to run the amplifier continuously without worrying about overheating. Even after hours of high-volume playback, the ST4.1000D remains cool and efficient, making it the ideal choice for long road trips or extended listening sessions.\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eHybrid Aluminum Alloy Heatsink for Optimum Dissipation\u003c\/li\u003e\n\u003cli\u003e2-ohm Stereo \u0026amp; 4-ohm Bridged Full Range Operation\u003c\/li\u003e\n\u003cli\u003eMOSFET Power Supply w\/ Audiophile Grade IRTM Transistors\u003c\/li\u003e\n\u003cli\u003eMilitary Grade SMT PCB Maintains Dynamic Performance\u003c\/li\u003e\n\u003cli\u003eDirect Short, Thermal, \u0026amp; Overload Circuits Protect Amplifier\u003c\/li\u003e\n\u003cli\u003e200mV-12V High Level or Low Level RCA Input\u003c\/li\u003e\n\u003cli\u003eQuick Disconnect RCA\/High Level Wire Harness\u003c\/li\u003e\n\u003cli\u003eQuick Disconnect Power and Speaker Output Harness\u003c\/li\u003e\n\u003cli\u003eVariable 12dB High Pass, Low Pass, \u0026amp; Subsonic Crossovers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStealth Series 4-Channel Digital Full Range Class-D Amplifier\u003c\/li\u003e\n\u003cli\u003ePower Rating :\n\u003cul\u003e\n\u003cli\u003eMax Power : 1000 Watts\u003c\/li\u003e\n\u003cli\u003eRMS Power (@ 2Ω) : 125 Watt x 4 Channel\u003c\/li\u003e\n\u003cli\u003eRMS Power (@ 4Ω) : 90 Watt x 4 Channel\u003c\/li\u003e\n\u003cli\u003eRMS Power Bridged (4Ω) : 250 Watt x 2 Channel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eBass Boost : N\/A\u003c\/li\u003e\n\u003cli\u003eTHD : \u0026lt;0.05%\u003c\/li\u003e\n\u003cli\u003eSpeaker Impedance : 4Ω\/8Ω\u003c\/li\u003e\n\u003cli\u003eInput Sensitivity : 500mV - 12.0V\u003c\/li\u003e\n\u003cli\u003eOperation Voltage : 11VDC - 16VDC\u003c\/li\u003e\n\u003cli\u003eFrequency Response : 20Hz - 30KHz\u003c\/li\u003e\n\u003cli\u003eSignal-to-Noise Ratio : 70dB\u003c\/li\u003e\n\u003cli\u003eCrossover (-12dB\/Oct)\n\u003cul\u003e\n\u003cli\u003eVariable High Pass : 35Hz - 250Hz\u003c\/li\u003e\n\u003cli\u003eVariable Low Pass : 35Hz - 250Hz\u003c\/li\u003e\n\u003cli\u003eVariable Subsonic : N\/A\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eDimensions : 6.5″\u003cb\u003eL\u003c\/b\u003e x 3.0″\u003cb\u003eW\u003c\/b\u003e x 1.5″\u003cb\u003eH\u003c\/b\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Soundstream","offers":[{"title":"Default Title","offer_id":47260609904828,"sku":"ST41000D","price":123.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/0741\/6508\/files\/ST4.1000D_05.jpg?v=1786443471","url":"https:\/\/11thstreetelectronic.com\/products\/soundstream-st41000d-1-000w-class-d-4ch-car-amplifier","provider":"11TH STREET ELECTRONIC INC","version":"1.0","type":"link"}
