These compact Class D amplifiers combine powerful performance, a fully bridgeable multi-channel architecture, and excellent efficiency with seamless real-world integration. Brilliant and precise treble, a controlled mid-range as well as tight, powerful bass – the 2-Series brings out every nuance of natural, powerful sound, outperforming the expectations of its class in both sound quality and output. Whether as a DIRECT, X-OVER, or DSP variant (coming in summer 2025): from flexible 6-channel setups for fullrange applications to dedicated mono powerhouses for subwoofers – the 2-Series offers tailored solutions for every configuration.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAMPLIFY 201 – The specialists for subwoofer performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUncompromising bass power in a compact format: The AMPLIFY 201 monoblock amplifiers are specifically designed for subwoofer upgrades and deliver powerful output with excellent control – ideal for deep, dynamic bass with maximum precision. With up to 750 W RMS at 1 Ohm, adjustable subsonic and lowpass filters, and phase control in the X-OVER version – or an uncompromised signal path in the DIRECT model – along with their compact footprint, the AMPLIFY 201 amplifiers are the perfect choice for targeted subwoofer upgrades in modern sound systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSound and power – above the standard\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe AMPLIFY 2-Series is more than just a range of application-specific solutions – it's a clear commitment to a very specific mission: to outperform expectations in each of those applications – both in sound quality and power delivery. All amplifiers in the series offer brilliant sound performance, minimal distortion, and an outstanding signal-to-noise ratio – combined with fully bridgeable multi-channel outputs for maximum output and installation flexibility. The result: a lineup that doesn’t define itself by its class, but sets new benchmarks within it – making AMPLIFY the first choice for those seeking application-focused performance without compromise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAMPLIFY DIRECT – Made for external DSPs\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe DIRECT models, featuring their DirectDSP inputs, are purpose-built for use in DSP-based audio systems that demand clean, efficient and transparent amplification. Especially due to the focus on essential control elements and core components, flawless operation is ensured. By eliminating conventional input filtering, they ensure uncompromised signal integrity and maximum clarity throughout the signal path. A high-quality gain stage and clipping LED enable precise level adjustment, while the minimalist input architecture keeps noise and distortion to an absolute minimum. A practical stereo\/mono switch for each stereo input also allows bridged operation with just a single RCA signal – eliminating the need for external Y-adapters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eForm follows performance\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe design of the HELIX AMPLIFY 2-Series blends modern functionality with a refined, technical aesthetic. Its compact dimensions allow for flexible installation, even in tight spaces. A removable top cover conceals all connections and controls, offering additional protection as well as a clean and streamlined appearance that highlights the amplifier’s high-quality character. Matte surfaces, sharp contours, and a minimalist design language create a sleek, exclusive look that integrates seamlessly into any modern vehicle interior.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eSpecification\u003c\/h2\u003e\n\u003cdiv id=\"ProductAccordion-collapsible_tab_CHMwtd-template--25535041831178__main-product\" class=\"collapsible__content accordion__content rte\"\u003e\n\u003cp\u003e\u003cstrong\u003ePart Number: \u003c\/strong\u003e\u003cstrong\u003eAmplify 201 Direct\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePower RMS  ≤ 1% THD+N @ 14.4 V\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e \u003c\/li\u003e\n\u003cli\u003e- @ 4 Ohms\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e1 x 250 Watts\u003c\/li\u003e\n\u003cli\u003e- @ 2 Ohms\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e1 x 450 Watts\u003c\/li\u003e\n\u003cli\u003e- @ 1 Ohm\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e1 x 750 Watts*\u003c\/li\u003e\n\u003cli\u003eMax. output power per channel\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003eUp to 850 Watts RMS @ 1 Ohm\u003c\/li\u003e\n\u003cli\u003eAmplifier technology\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003eClass D\u003c\/li\u003e\n\u003cli\u003eInputs\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e2 x RCA \/ Cinch\u003c\/li\u003e\n\u003cli\u003e1 x Remote In\u003c\/li\u003e\n\u003cli\u003eInput sensitivity\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e0.5 - 8 Volts\u003c\/li\u003e\n\u003cli\u003eInput impedance\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e8 kOhms\u003c\/li\u003e\n\u003cli\u003eOutputs\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e1 x Speaker output\u003c\/li\u003e\n\u003cli\u003eFrequency response\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e10 Hz - 450 Hz\u003c\/li\u003e\n\u003cli\u003eSignal-to-noise ratio (A-weighted)\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e114 dB @ full power\u003c\/li\u003e\n\u003cli\u003eDistortion (THD @ 100 Hz, 1 W into 4 Ohms)\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e\u0026lt; 0.003%\u003c\/li\u003e\n\u003cli\u003eDistortion (THD+N @ 100 Hz, 1 W into 4 Ohms)\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e\u0026lt; 0.02 %\u003c\/li\u003e\n\u003cli\u003eDamping factor\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e200\u003c\/li\u003e\n\u003cli\u003eOperating voltage\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e10.5 - 16 Volts (max. 5 sec. down to 6 Volts)\u003c\/li\u003e\n\u003cli\u003eIdle current\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e1,100 mA\u003c\/li\u003e\n\u003cli\u003eFuse\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e2 x 30 A LP-Mini-fuse (APS)\u003c\/li\u003e\n\u003cli\u003ePower rating\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003eDC 12 V ⎓ 80 A max.\u003c\/li\u003e\n\u003cli\u003eOperating temperature range\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e-40 °C to +70 °C\u003c\/li\u003e\n\u003cli\u003eAdditional features\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003eStart-Stop capability, Clipping LED, DirectDSP inputs\u003c\/li\u003e\n\u003cli\u003eDimensions (H x W x D)\u003cspan class=\"Apple-tab-span\"\u003e \u003c\/span\u003e40 x 248 x 114 mm \/\u003c\/li\u003e\n\u003cli\u003e1.58 x 9.76 x 4.49”\u003c\/li\u003e\n\u003cli\u003e* Continuous 1 Ohm power achieved only with music signal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cdiv id=\"ProductAccordion-collapsible_tab_BfyGFk-template--25535041831178__main-product\" class=\"collapsible__content accordion__content rte\"\u003e\n\u003cp\u003e\u003cstrong\u003e2 Year Warranty\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHELIX AMPLIFY 201 DIRECT Amplifier\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003cli\u003eAllen keys\u003c\/li\u003e\n\u003cli\u003eFuse\u003c\/li\u003e\n\u003cli\u003eInstruction manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Helix","offers":[{"title":"Default Title","offer_id":45500747251891,"sku":null,"price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/5638\/0339\/files\/57_1a456b84-cd16-425c-b15b-b50595d4fe14.jpg?v=1778513883","url":"https:\/\/www.edgecustomaudio.net\/products\/helix-amplify-201-direct-subwoofer-amp-dsp-input-mono-sub-amplifier-750w-rms-1","provider":"Edge Custom Audio","version":"1.0","type":"link"}
