It provides four amplified channels for speakers or can be bridged into two higher-output channels. Its small chassis helps solve installation-space limitations common in compact vehicles and powersports applications.\u003c\/p\u003e\u003cp\u003eAt 14.4 volts, the KS-DR1004D delivers 45 watts RMS to each of four channels at 4 ohms across 20 Hz to 20 kHz. It can also be configured for 90 watts RMS x 2 in bridged operation with 4-ohm loads. This makes it suitable for powering full-range speakers in a four-channel setup or for a smaller two-channel-plus-subwoofer system.\u003c\/p\u003e\u003cp\u003eThe amplifier supports both RCA low-level inputs and speaker-level inputs, allowing it to work with aftermarket receivers as well as compatible factory-installed head units. Signal-sensing auto power control is available when using the speaker-level input. Independent A-channel and B-channel input, sensitivity, and filter controls support system-specific adjustment.\u003c\/p\u003e\u003cp\u003eVariable high-pass and low-pass filters can be adjusted from 50 Hz to 200 Hz, helping direct appropriate frequencies to full-range speakers or a subwoofer. The selectable filtering can also be turned off for full-band operation. A 98 dB signal-to-noise ratio and separated preamplifier and power-amplifier circuit boards are engineered to help reduce unwanted radiation noise.\u003c\/p\u003e\u003cp\u003eFor outdoor-oriented applications, the main printed circuit boards use conformal coating for added protection from moisture, condensation, and airborne contaminants such as salt spray. A large low-pass-filter coil supports stable signal handling at higher listening levels. With its compact 145 x 45 x 99 mm footprint, the KS-DR1004D is a practical amplifier upgrade where mounting room is limited.\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 up to four speakers from a compact, efficient amplifier chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridgeable Output:\u003c\/strong\u003e Configures as two channels at 90 watts RMS each into 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Crossovers:\u003c\/strong\u003e Adjustable 50-200 Hz HPF and LPF settings tailor speaker frequency range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Level Input:\u003c\/strong\u003e Connects to compatible factory speaker outputs without RCA preouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal-Sensing Turn-On:\u003c\/strong\u003e Supports automatic power activation through the high-level input.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConformal-Coated PCBs:\u003c\/strong\u003e Adds protection against moisture, condensation, and airborne contaminants.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe KS-DR1004D uses a compact chassis, conformal-coated main circuit boards, and separated preamplifier and power-amplifier circuit boards. Its control panel includes separate A-channel and B-channel filter-frequency, filter-mode, and input-sensitivity adjustments. A protective cover is supplied for the control panel after setup.\u003c\/p\u003e\u003cp\u003eInstall the amplifier securely in a dry location with adequate ventilation and clearance for heat dissipation; it should not be mounted under carpet or where it can interfere with driving or safety equipment. Use a 12-volt negative-ground electrical system, connect the ground lead to suitable chassis ground, and place a protective fuse near the battery. The amplifier supports RCA-input installations or speaker-level connections, with 2-ohm minimum stereo loads and 4-ohm minimum bridged loads.\u003c\/p\u003e","brand":"Kenwood","offers":[{"title":"Default Title","offer_id":45633161199686,"sku":"KS-DR1004D","price":233.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/818Qw-R_sOL.jpg?v=1784406938","url":"https:\/\/audiowatt.store\/products\/jvc-ks-dr1004d-4-channel-compact-class-d-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
