This effectively overcomes the common load dependency issues of Class-D amplifiers, improving distortion and enhancing frequency response, thereby significantly enhancing sound quality and performance.\u003cbr\u003e\u003cbr\u003e\u003c\/li\u003e\n\u003cli\u003eAudiophile-Grade Components: The V3 Mono incorporates the high-end TPA3255 Class-D amp chip, paired with well-known components such as Japanese Nichicon filter capacitors, ELNA capacitors, German WIMA capacitors, and Japanese Sumida inductors, etc. Additionally, it features an upgraded four-layer PCB. This combination not only ensures high power output but also achieves a THD as low as 0.006%, a SINAD of 101dB, and an SNR of 123dB. As a result, the fidelity and quality of the audio are assured.\u003cbr\u003e\u003cbr\u003e\u003c\/li\u003e\n\u003cli\u003eAdvanced Cooling: Utilizing Fosi Audio's pioneering full-body heat dissipation design, the TPA3255 amplifier chip is placed at the bottom and tightly integrated with the chassis, allowing heat to be effectively dissipated through the casing. Coupled with dual side ventilation holes that enhance internal airflow, this ensures the V3 Mono can deliver stable, high-power output over extended periods.\u003cbr\u003e\u003cbr\u003e\u003c\/li\u003e\n\u003cli\u003eUser-Friendly Design: Supports both XLR\/¼\" TRS balanced and RCA single-ended(with gain selection) inputs, with an easy toggle switch for selection.

To minimize interference, route power cables and signal cables on opposite sides of the vehicle (e.g., signal cables on the left, power cables on the right).\u003cbr\u003e4. Please use properly rated cables. Power and ground cables must be AWG #4, and the REM wire should be AWG #16 to #18.\u003cbr\u003e5. Do not connect high-level input and RCA low-level input simultaneously.\u003cbr\u003e6. Multiple speakers can be connected in parallel to a single channel. In stereo mode, total impedance per channel must not be lower than 2 Ω; in bridged mode, not lower than 4 Ω.\u003cbr\u003e7. Observe correct polarity for all power and audio connections to prevent short circuits or damage to the amplifier and vehicle.\u003cbr\u003e8. The CA30 features cooling fins on the top panel. For optimal cooling, please install the amplifier with the fins facing upward, maintain 5–10 cm of clearance, and do not cover the fins during operation.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003ca data-encoded-attr-charset=\"dXRmLTg=\" data-encoded-tag-value=\"\" data-encoded-tag-name=\"meta\"\u003e\u003c\/a\u003e\u003cimg src=\"https:\/\/fosiaudio.com\/cdn\/shop\/files\/B0GDXGRBK1.PT06.jpg?v=1770189377\u0026amp;width=1600\" alt=\"Fosi Audio CA30 Car Amplifier - Fosi Audio\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u0026nbsp;\u003c\/p\u003e\n\u003cp\u003e\u003ca data-encoded-attr-charset=\"dXRmLTg=\" data-encoded-tag-value=\"\" data-encoded-tag-name=\"meta\"\u003e\u003c\/a\u003e\u003cstrong\u003e2 Years Warranty\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Fosi Audio","offers":[{"title":"Default Title","offer_id":51270527615209,"sku":null,"price":1199.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/5424\/8169\/files\/800.png?v=1781464055"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0766\/5424\/8169\/collections\/V3_MONO.png?v=1781597203","url":"https:\/\/www.futex.hk\/en\/collections\/pre-amplifiers.oembed","provider":"Futex","version":"1.0","type":"link"}
