It is a practical solution for systems that need more output than a receiver's built-in amplifier can provide while conserving installation space. Its small footprint makes it suitable for locations where a conventional full-size amplifier may be difficult to mount.\u003c\/p\u003e\u003cp\u003eWith 45 watts RMS per channel, the KAC-M1814 can power four compatible speakers or be configured in bridged two-channel operation. It supports 2-ohm stereo loads and 4- to 8-ohm bridged loads, allowing it to work with a range of speaker layouts. Variable high-pass and low-pass filters help tailor the signal for full-range speakers or selected system configurations.\u003c\/p\u003e\u003cp\u003eThis amplifier is intended for listeners building a compact upgrade in a vehicle, boat, or powersports application. Speaker-level input with signal-sensing turn-on supports integration with receivers that do not provide dedicated RCA preamp outputs. RCA inputs are also available for use with aftermarket receivers and other line-level sources.\u003c\/p\u003e\u003cp\u003eKenwood uses a Class D digital amplifier platform with a Power MOS-FET switching power supply to keep the chassis compact. Separate preamp and power-amp sections are designed to help reduce radiation noise. Independent A and B channel gain controls and separately adjustable crossover sections provide useful setup flexibility.\u003c\/p\u003e\u003cp\u003eFor outdoor-oriented installations, the KAC-M1814 includes conformal coating to help protect the circuit board from rust and vibration-related exposure. Its covered connectors are designed to help keep out water and dust. The amplifier fits neatly into a system using four speakers, or it can be used bridged for two compatible channels where higher per-channel output is needed.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Class D Amplification:\u003c\/strong\u003e Adds 45 watts RMS to each of four channels.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridgeable Output:\u003c\/strong\u003e Supports two-channel bridged operation at compatible 4-ohm loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker-Level Input:\u003c\/strong\u003e Connects to systems without RCA preamp outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal-Sensing Turn-On:\u003c\/strong\u003e Powers on when an input signal is detected.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Crossovers:\u003c\/strong\u003e Adjustable high-pass and low-pass filtering from 50 to 200 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConformal-Coated Circuit Board:\u003c\/strong\u003e Helps protect the electronics in marine and motorsports use.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe KAC-M1814 uses a compact aluminum heat-sink chassis with a 145 x 45 x 99 mm enclosure size. Its Class D design, covered connector arrangement, and conformal-coated circuit board suit installations where space and environmental exposure are considerations. The amplifier also uses a Power MOS-FET switching power supply and separate preamp and power-amp sections.\u003c\/p\u003e\u003cp\u003eMount the amplifier in a secure location with appropriate ventilation and connect it to a 12-volt DC vehicle electrical system. It can accept RCA line-level inputs or speaker-level inputs, while its included DC cable and RCA cables support basic installation connections. Set the A and B channel gain and crossover controls to match the connected speakers and chosen system layout.\u003c\/p\u003e","brand":"Kenwood","offers":[{"title":"Default Title","offer_id":45633058177094,"sku":"KAC-M1814","price":200.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71FANe4bUgL.jpg?v=1784404356","url":"https:\/\/audiowatt.store\/products\/kenwood-kac-m1814-compact-4-channel-marine-digital-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
