It is designed to drive front and rear speakers from a single chassis while giving installers crossover and gain controls for system tuning. Its four-channel layout suits vehicles receiving amplified component or coaxial speakers.\u003c\/p\u003e\u003cp\u003eWith 60 watts RMS per channel at 4 ohms and 90 watts RMS per channel at 2 ohms, the XED4004D provides a practical power upgrade over many head-unit amplifier sections. It can be used in a conventional four-speaker installation or in a three-channel arrangement that bridges one channel pair. The amplifier supports a 2-ohm minimum stereo load and a 4-ohm minimum bridged load.\u003c\/p\u003e\u003cp\u003eClass-D topology and a full PWM power supply support efficient operation in a small footprint. The amplifier has a 10 Hz to 30 kHz bandwidth, adjustable gain, and selectable high-pass, full-range, or low-pass crossover modes. These controls allow the amplifier to be configured around the speakers and system goals rather than relying solely on source-unit settings.\u003c\/p\u003e\u003cp\u003eFor signal integration, the XED4004D accepts both low-level RCA and high-level speaker inputs. This gives installers an option for connecting an aftermarket receiver with RCA outputs or a compatible factory-radio system without RCA preouts. Input sensitivity ranges are provided for both connection types to help match the amplifier to the source signal.\u003c\/p\u003e\u003cp\u003eThe XED4004D fits well into a speaker-focused upgrade path, such as powering front components and rear fill, or running a front stage with a bridged pair for another compatible load. Its compact 6.3 by 4.7 inch chassis is easier to place than larger conventional amplifiers, provided airflow remains available. A separate power-and-ground wiring kit, inline fuse protection, signal wiring, speakers, and installation hardware are required for a complete installation.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Output:\u003c\/strong\u003e Powers front and rear speakers from one amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClass-D Topology:\u003c\/strong\u003e Delivers efficient amplified power in a compact chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Crossover:\u003c\/strong\u003e Choose high-pass, full-range, or low-pass operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCA And High-Level Inputs:\u003c\/strong\u003e Supports aftermarket or compatible factory-radio signal connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVega Bass Boost:\u003c\/strong\u003e Provides adjustable 0 to +12 dB boost at 45 Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStatus LEDs:\u003c\/strong\u003e Indicate normal power operation or a protection fault.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe XED4004D uses a lightweight aluminum chassis that also helps dissipate heat. Its side-panel layout includes power terminals, speaker outputs, gain adjustment, crossover controls, input connections, and status indicators. The specified chassis dimensions are 6.3 x 4.7 x 1.8 inches.\u003c\/p\u003e\u003cp\u003eMount the amplifier on a solid surface with ventilation around it and keep the controls accessible for setup. Use at least 8-gauge power and ground wire, protect the positive power lead with an external fuse near the battery, and connect the ground securely to bare vehicle chassis metal. Use 2-ohm-or-higher speaker loads in stereo operation or 4-ohm-or-higher loads when bridging channels.\u003c\/p\u003e","brand":"Cerwin Vega","offers":[{"title":"Default Title","offer_id":45620597063750,"sku":"CER-XED4004D","price":135.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/5193EsCNcpL.jpg?v=1784371067","url":"https:\/\/audiowatt.store\/products\/cerwin-vega-xed4004d-4-channel-class-d-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
