Built for superior audio performance, it features premium Korean components and Sky High Car Audio’s OFC Internal Wiring. With DS18’s reputation as the LOUDEST in pro audio and Steve Meade’s industry-standard installation peripherals, this amp is built for extreme power and convenience.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003e“When we first started working on the SMD amplifiers with DS18, I made it clear that these amplifiers needed to stand out from the rest.\" says Steve Meade.\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eWith the SMD-200.4AB, we achieved that and more. What sets the SMD-200.4AB apart is its unique clear half-top design, ensuring efficient heat dissipation through a reverse-mounted board and dual cooling fans. It also features an exclusive built-in SMD VM-1 digital\/analog-style LED voltmeter that monitors power draw in real-time. Customizable RGB lighting adds another layer of personalization, allowing you to match your vehicle’s interior or create dynamic light displays.\u003c\/p\u003e\n\u003cp\u003eManufactured using premium components from Korea, this amplifier guarantees the reliability and powerful sound quality that Steve Meade Designs is known for. The SMD-200.4AB is not only visually striking but also engineered for top-tier performance. It delivers an impressive 150W x 4 RMS at 4-ohm, 200W x 4 RMS at 2-ohm, and 400W x 2 RMS bridged at 4-ohm: driving even the most demanding setups with ease.\u003c\/p\u003e\n\u003cp\u003eThe SMD-200.4AB is designed for audiophiles seeking superior sound quality. As a Class AB amplifier, it prioritizes clarity and detail, delivering pristine audio performance. Equipped with a precision attenuation knob for easy bass control, it maintains a .10% THD, ensuring exceptional Total Harmonic Distortion levels. With 4 AWG power and ground inputs and a 120A fusing requirement, it’s built for robust power delivery. Additional features include selectable 2\/4 channel inputs and Tiffany RCA connectors for the highest quality signal transfer in your setup.\u003c\/p\u003e\n\u003cp\u003eCrafted with precision using only the best components, DS18’s SMD-200.4AB is a full-range amplifier capable of powering anything—from subs and tweeters to midbass, vocals, and any front and rear combination of speakers. Its advanced protection suite includes thermal, overload, DC output, short circuit, and voltage input protection, ensuring safe operation in any setup.\u003c\/p\u003e\n\u003cp\u003ePush the limits of what’s possible with the SMD-200.4AB’s groundbreaking design and raw power!\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/section\u003e","brand":"DS18","offers":[{"title":"Default Title","offer_id":51681405075822,"sku":null,"price":479.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0060\/1918\/6791\/files\/smd-200.4ab-2000x2000_700x_5b6ff1b9-dac0-40a8-962c-84e4f04708e2.jpg?v=1731525219","url":"https:\/\/www.droppinhzcaraudio.com\/products\/smd-4-channel-class-ab-amplifier-with-vm-1-voltmeter-and-digital-led-lights-4-x-200w-at-2-ohm-steve-meade-designs","provider":"Droppin HZ Car Audio","version":"1.0","type":"link"}
