{"product_id":"4-channel-class-d-digital-amplifier","title":"4-Channel Class D Digital Amplifier","description":"The Kenwood KAC-M1804 is a compact 4-channel digital amplifier designed for car, motorcycle, and boat applications. It utilizes Class D amplification, providing 45 Watts RMS x 4 at 4 ohms, with a total maximum output power of 400W. This amplifier is CEA-2006 compliant, ensuring it meets industry standards for power output measurement.\n\nKey features include a signal sensing turn-on function, which allows the amplifier to power on and off automatically with the audio source, eliminating the need for a separate remote turn-on wire. It offers both RCA and speaker-level inputs, providing versatile connectivity options for various head units and source devices. The amplifier also boasts a Power MOS-FET switching power supply for efficient operation.\n\nBuilt with an extruded aluminum heat sink, the KAC-M1804 is designed to dissipate heat effectively, contributing to its longevity. Its compact dimensions (140 x 34 x 90mm) make it suitable for installations where space is limited. The unit operates on a voltage range of 11V to 16V with a maximum current consumption of 15A. It is 4-ohm stable per channel and is not bridgeable.\n\nThe amplifier's specifications include an input impedance of 10kΩ, a signal-to-noise ratio of 90dB (CEA-2006 rated at 74dBa reference), and a frequency response of 20Hz ~ 20Hz. The product comes with a DC cable and features PCB protection by conformal coating for enhanced durability.","brand":"Kenwood","offers":[{"title":"Default Title","offer_id":52662814605624,"sku":"KAC-M1804","price":119.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687499700.jpg?v=1784321311","url":"https:\/\/store.motormia.co\/products\/4-channel-class-d-digital-amplifier","provider":"MOTORMIA","version":"1.0","type":"link"}
