It delivers 300 watts RMS to a 4-ohm load or 500 watts RMS to a 2-ohm load, giving installers practical options for matching a compatible subwoofer configuration. Its mono-channel design focuses on low-frequency reinforcement rather than full-range speaker amplification.\u003c\/p\u003e\u003cp\u003eThis amplifier is suited to drivers who want stronger bass from an aftermarket subwoofer while keeping the installation footprint manageable. The compact chassis measures 6-11\/16 inches wide, 2-3\/16 inches high, and 7-3\/8 inches deep. That size can be useful for under-seat, cargo-area, or concealed amplifier locations where mounting space is limited.\u003c\/p\u003e\u003cp\u003eThe KAC-D5101 uses a variable low-pass filter to direct bass frequencies to the connected subwoofer. Its adjustable bass boost operates at 40 Hz, allowing measured low-frequency adjustment when system tuning calls for it. A 20 Hz to 200 Hz frequency response supports its role as a dedicated bass amplifier.\u003c\/p\u003e\u003cp\u003eKenwood's Dual Sigma Drive negative-feedback circuit is designed to improve damping factor and help control unwanted subwoofer movement. The amplifier also uses a Power MOS-FET switching power supply for its Class D platform. Together, these design elements support controlled low-frequency operation in a compact mono amplifier.\u003c\/p\u003e\u003cp\u003eInstallation flexibility includes RCA line-level input and speaker-level input capability. Signal sensing turn-on can help the amplifier work with systems that do not provide a conventional remote-turn-on lead. With support for 2-ohm through 8-ohm speaker loads, it can be integrated into a range of properly wired subwoofer systems.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMono Class D Design:\u003c\/strong\u003e Dedicated single-channel amplification for a subwoofer system.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e500W RMS at 2 Ohms:\u003c\/strong\u003e Supplies substantial continuous power to compatible 2-ohm loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Low-Pass Filter:\u003c\/strong\u003e Adjusts the bass frequency range sent to the subwoofer.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e40 Hz Bass Boost:\u003c\/strong\u003e Provides adjustable low-frequency boost from 0 to +18 dB.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker-Level Input:\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 switch on when it detects an input signal.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe KAC-D5101 uses an extruded aluminum heat-sink design and a compact rectangular chassis. Its battery and ground connections use M6 screw-type terminal blocks, while the speaker output uses an M4 screw-type terminal block. Two 30-amp fuses are fitted for circuit protection.\u003c\/p\u003e\u003cp\u003eFor installation, mount the amplifier securely in a ventilated location and use a properly fused 12-volt vehicle power connection. Connect a subwoofer system with a final impedance between 2 and 8 ohms, then set input sensitivity, low-pass filter frequency, and bass boost to suit the source unit and subwoofer. RCA input is available for aftermarket source units, while speaker-level input and signal sensing are useful for compatible factory-system upgrades.\u003c\/p\u003e","brand":"Kenwood","offers":[{"title":"Default Title","offer_id":45633058046022,"sku":"KAC-D5101","price":250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/6197v7SI25L.jpg?v=1784404271","url":"https:\/\/audiowatt.store\/products\/kenwood-kac-d5101-class-d-mono-car-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
