It provides a practical upgrade path for vehicles where factory amplification is limited or where separate amplifiers would take up too much space. With dedicated A\/B and subwoofer channel sections, it supports a complete speaker-and-subwoofer system from a single amplifier.\u003c\/p\u003e\u003cp\u003eAt 4 ohms, the KAC-D8105 is rated for 50 watts RMS across each of four A\/B channels plus 300 watts RMS for the subwoofer channel. At 2 ohms, its ratings increase to 75 watts RMS x 4 and 500 watts RMS x 1. This makes it suitable for systems that need clean power for front and rear speakers while retaining a separate low-frequency channel for a compatible subwoofer.\u003c\/p\u003e\u003cp\u003eThe A\/B channels have a 20 Hz to 50 kHz frequency response, while the subwoofer channel is specified from 20 Hz to 200 Hz. Variable high-pass and low-pass filters help divide frequencies between speakers and subwoofer for a more purposeful system setup. A variable subwoofer bass boost control is also provided for low-frequency adjustment at 40 Hz.\u003c\/p\u003e\u003cp\u003eKenwood equips the KAC-D8105 with Dual Sigma Drive negative-feedback technology, which is intended to improve damping and control speaker movement. Its Power MOS-FET switching power supply supports the amplifier's efficient Class D design. Independent gain adjustment for the A\/B and subwoofer sections allows installers to set levels for the full-range and bass portions of the system separately.\u003c\/p\u003e\u003cp\u003eThe amplifier accepts both RCA and speaker-level input signals, making it useful with aftermarket receivers as well as many factory-radio installations. Signal-sensing turn-on can activate the amplifier from a speaker-level input signal when applicable. Its compact 9-inch-wide chassis is designed for installations where space is limited, including many under-seat or trunk locations.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFive-Channel Configuration:\u003c\/strong\u003e Powers four speakers plus one dedicated subwoofer channel from one amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1600W Maximum Power:\u003c\/strong\u003e Provides the manufacturer's stated maximum-power rating for the complete amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2-Ohm Load Capability:\u003c\/strong\u003e Supports rated operation with compatible 2-ohm speaker loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Crossovers:\u003c\/strong\u003e High-pass and low-pass filters help direct frequencies to appropriate speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker-Level Inputs:\u003c\/strong\u003e Supports connection to compatible factory-radio speaker outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal-Sensing Turn-On:\u003c\/strong\u003e Can detect an incoming speaker-level signal for activation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe KAC-D8105 uses an extruded aluminum heat-sink design and a compact Class D layout. Its power and ground connections use M6 screw-type terminal blocks, while the speaker outputs use M4 screw-type terminal blocks. The chassis measures 9 inches wide by 2-3\/16 inches high by 7-3\/8 inches deep and weighs 4.5 pounds.\u003c\/p\u003e\u003cp\u003ePlan the installation around the amplifier's dimensions, ventilation needs, and the vehicle's 11 to 16 volt operating range. Connect a source through RCA line inputs or the speaker-level input, then set the A\/B high-pass and subwoofer low-pass controls to suit the speakers and subwoofer being used. Match loads carefully: the bridged A\/B outputs require a 4- to 8-ohm load, while the amplifier is rated for 2- to 8-ohm allowable speaker loads.\u003c\/p\u003e","brand":"Kenwood","offers":[{"title":"Default Title","offer_id":45633058144326,"sku":"KAC-D8105","price":477.7,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61oFKOmDAVL.jpg?v=1784404319","url":"https:\/\/audiowatt.store\/products\/kenwood-kac-d8105-5-channel-class-d-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
