It provides 50 watts RMS to each of four channels at 4 ohms, making it suited to powering upgraded front and rear speakers. Its compact chassis helps address installations where space behind panels, beneath seats, or in a trunk is limited.\u003c\/p\u003e\u003cp\u003eThis amplifier is a practical choice for listeners who want clearer, more controlled output than a typical factory head unit can provide. It supports both RCA line-level input and speaker-level input, allowing it to work with a variety of aftermarket or factory-source systems. Signal-sensing turn-on support can simplify integration when using a speaker-level source.\u003c\/p\u003e\u003cp\u003eThe KAC-D3104 uses Class D amplification and a Power MOS-FET switching power supply in a compact format. Its frequency response extends from 20 Hz to 50 kHz, supporting full-range speaker systems and high-resolution audio playback. Kenwood's Dual Sigma Drive negative-feedback circuit is designed to improve damping and signal accuracy.\u003c\/p\u003e\u003cp\u003eEach A\/B channel pair has selectable variable high-pass or low-pass filtering from 50 Hz to 200 Hz. This flexibility lets the amplifier run full-range speakers with high-pass filtering or support a filtered speaker\/subwoofer configuration when the system design calls for it. Bass boost is available on the B-channel section at 40 Hz, adjustable from 0 dB to +18 dB.\u003c\/p\u003e\u003cp\u003eFor larger system plans, the KAC-D3104 can also be bridged to deliver 150 watts RMS to each of two 4-ohm channels. That makes it adaptable for a two-channel higher-power speaker setup, while its standard four-channel mode is appropriate for front-and-rear speaker upgrades. Proper impedance matching, power wiring, grounding, and gain setup remain important for reliable operation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Class D Design:\u003c\/strong\u003e Powers four speakers from a compact amplifier chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e50W RMS x 4 at 4 Ohms:\u003c\/strong\u003e Delivers dedicated power for full-range speaker upgrades.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Load Capability:\u003c\/strong\u003e Produces 75W RMS per channel at 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridgeable Channels:\u003c\/strong\u003e Configures as two 150W RMS channels at 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable HPF and LPF:\u003c\/strong\u003e Helps match output to speaker system needs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker-Level Input:\u003c\/strong\u003e Supports integration with systems lacking RCA outputs.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe KAC-D3104 uses an extruded aluminum heat-sink design and a compact 6-11\/16 by 2-3\/16 by 7-3\/8 inch chassis. Its terminal layout includes M6 screw-type battery and ground terminals plus M4 screw-type speaker output terminals. The design combines four channels of Class D amplification with separate A- and B-channel filter and sensitivity controls.\u003c\/p\u003e\u003cp\u003eInstall the amplifier in a dry, ventilated location with secure mounting and appropriate power, ground, remote-turn-on, signal, and speaker wiring. Use four-channel mode for separate front and rear speakers, or bridge paired channels only with a 4- to 8-ohm bridged load. Set input sensitivity and crossover controls after matching the amplifier to the source unit and connected speakers.\u003c\/p\u003e","brand":"Kenwood","offers":[{"title":"Default Title","offer_id":45633056866374,"sku":"KAC-D3104","price":250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/51CSwUyqMrL.jpg?v=1784404232","url":"https:\/\/audiowatt.store\/products\/kenwood-kac-d3104-4-channel-class-d-power-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
