It provides four amplified channels in a compact full-range format, making it suitable for vehicles where a factory or aftermarket head unit needs more output capability. Its universal vehicle fitment means installation planning is based on available mounting space and the vehicle's electrical system.\u003c\/p\u003e\u003cp\u003eRated for 125 watts RMS per channel at 4 ohms or 200 watts RMS per channel at 2 ohms, the BRL800.4 can power four speakers with substantial headroom. It can also be configured for two-channel bridged operation, producing 400 watts RMS per bridged channel at 4 ohms. This flexibility supports conventional four-speaker upgrades as well as systems that use one channel pair for speakers and another bridged pair for compatible subwoofers.\u003c\/p\u003e\u003cp\u003eThe amplifier uses Hifonics Super D Class architecture with a Class-D chipset and half-bridge design. This approach is intended to provide efficient power delivery across its 15Hz-30kHz frequency response range. An iron-core transformer, Ultra-Fi MOSFET output devices, and an ultra-low-EMI design are part of its power and output-stage construction.\u003c\/p\u003e\u003cp\u003eBuilt-in variable high-pass and low-pass filters allow each channel pair to be tailored for the speakers connected to it. Both filters adjust from 40Hz to 2kHz at a 12dB-per-octave slope, while the built-in bass control provides additional system adjustment. The 0.2-9V input range accommodates a broad range of source-unit signal levels.\u003c\/p\u003e\u003cp\u003eThe BRL800.4 incorporates Intelligent Power Management System protection functions for over-voltage, under-voltage, short-circuit, overcurrent, and thermal conditions. Its illuminated logo can be set to constant blue lighting, VU meter operation, or off. The VU display can provide a visual indication of audio level during setup, while final gain setting should be performed with appropriate tuning practices.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Output:\u003c\/strong\u003e Powers four speakers or supports stereo and bridged system layouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e800 Watts RMS Total:\u003c\/strong\u003e Delivers up to 4 x 200 watts RMS at 2 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridged Capability:\u003c\/strong\u003e Produces 2 x 400 watts RMS at 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Crossovers:\u003c\/strong\u003e High-pass and low-pass filters help match amplifier output to speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVU Meter Logo:\u003c\/strong\u003e Select constant blue illumination, audio-reactive VU mode, or off.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Circuitry:\u003c\/strong\u003e Helps guard against voltage, current, short-circuit, and thermal faults.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe BRL800.4 uses a black chassis with a mass-loaded extruded aluminum heat sink for thermal management. Its construction includes a multilayer surface-mount PCB, iron-core transformer, Ultra-Fi MOSFET output devices, nickel-plated RCA jacks, and angled molded connection terminals. These elements are designed to keep connections accessible while maintaining a clean wiring profile.\u003c\/p\u003e\u003cp\u003eMount the amplifier securely in a location with adequate airflow and avoid mounting it upside down. Use a properly fused power connection, a short and secure chassis ground, and speaker wiring that maintains a 2-ohm minimum load per unbridged channel or 4 ohms per bridged channel. The amplifier accepts RCA inputs and supports speaker-level inputs for integration with compatible factory or aftermarket source units.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631908282438,"sku":"BRL800-4","price":311.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61Ud_Q78qQL.jpg?v=1784386704","url":"https:\/\/audiowatt.store\/products\/hifonics-brl800-4-4-channel-car-audio-amplifier","provider":"Audio Watt Store","version":"1.0","type":"link"}
