Contact us for details \u0026amp; exceptions.\u003cbr\u003e--\u003cbr\u003eSound Quality Rivaling Class AB Amps:\u003cbr\u003eThe SS4b is a discrete circuit full range class D amp that can crank out over 350 Watts per channel at 2-ohm stereo, with less than 1% THD+N. All this power fits into an SS chassis measuring only 6.875″ wide by 11.81″ long. By using discrete class D circuitry instead of a chipset we were able to get ultra-low distortion AND high power, contrary to the majority of small chassis class D amps on the market today. Not only does the sound quality of the SS amps trump other class D designs, but they also rival high-quality class AB designs.\u003cbr\u003e\u003cbr\u003eTake the SS amp challenge, compare the sound of an SS amp to similar power class AB amps and you will experience the future of high efficiency AND high fidelity.\u003cbr\u003e\u003cbr\u003eVersatility:\u003cbr\u003eSS amps feature individually selectable high pass and low pass crossovers with frequency bands from 50Hz-5kHz, making them adaptable to virtually any system configuration. We used heavy duty set screw blocks for speaker and power terminals to ensure connections are solid and durable.\u003cbr\u003e\u003cbr\u003eSS amps are smaller, more powerful, generate less heat, and just sound better than other class D amps on the market. This makes them the ideal choice for today’s space cramped interiors. \u003cbr\u003e\u003cbr\u003e\u003cbr\u003eSPECS\u003cbr\u003eTest Voltage 14.4\u003cbr\u003eChannels 4\u003cbr\u003eCont Wattage @ 4ohm 250x4 \/ 700x2\u003cbr\u003eCont Wattage @ 2ohm 350x4\u003cbr\u003eMax Current Draw - Amperage 110\u003cbr\u003eS\/N Ratio \u0026gt;105dB\u003cbr\u003eInput Voltage Sensitivity 8 - 0.2\u003cbr\u003ePass-Through Output No\u003cbr\u003eRemote Subwoofer Control Yes\u003cbr\u003ePower Wire Guage In 4\u003cbr\u003eSpeaker Wire Gauge Out 10\u003cbr\u003eDimensions: in 11.81 x 6.88 x 2.14\u003cbr\u003eDimensions: mm 300 x 175 x 54.5\u003cbr\u003eShipping Weight - lbs 11","brand":"DD Audio","offers":[{"title":"Default Title","offer_id":31402789961865,"sku":"SS4b","price":690.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0277\/0511\/4761\/products\/DD-Audio-SS4b-High-Performance-4ch-Amplifier-1_e8732521-c467-4a36-94dd-aa6a3b269ffb.jpg?v=1611607691","url":"https:\/\/soundsgoodtn.myshopify.com\/products\/dd-audio-ss4b-high-performance-4ch-amplifier","provider":"Sounds Good Stereo Nashville","version":"1.0","type":"link"}
