Its full-range Super D-Class design supports conventional multi-speaker upgrades while keeping the amplifier package relatively compact. With four amplified channels and bridgeable operation, it offers flexible options for systems that need more output and tuning control than a factory or aftermarket receiver alone can provide.\u003c\/p\u003e\u003cp\u003eRated output is 4 x 100 watts at 4 ohms or 4 x 200 watts at 2 ohms, with two bridged channels rated at 400 watts each into 4 ohms. This makes it suited to powering compatible component speakers, coaxial speakers, or a combination of speakers and properly matched bridged loads. Its 10 Hz to 45 kHz frequency response supports full-range audio applications rather than subwoofer-only use.\u003c\/p\u003e\u003cp\u003eThe A800.4D uses Hifonics Ultra-Fi MOSFET output devices and a pulse-width-modulated Twin Turbo Coil power supply. Its Full Range Super D-Class topology is engineered for efficient operation, while the aluminum alloy heat sink helps move heat away from the amplifier circuitry. Surface-mount construction is also used to help the internal electronics tolerate vehicle vibration.\u003c\/p\u003e\u003cp\u003eFor system tuning, the amplifier includes Accu-Cross electronic crossover controls, selectable operating modes, and adjustable high-pass and low-pass filtering. A variable bass EQ provides 0 to 12 dB of boost centered at 45 Hz. These controls allow an installer to direct suitable frequency ranges to connected speakers or bridged channels without relying entirely on source-unit processing.\u003c\/p\u003e\u003cp\u003eInstallation flexibility includes RCA inputs as well as speaker-level audio inputs for integration with a wider range of source units. The amplifier can be activated by a conventional remote turn-on lead or by signal sensing through its high-level inputs. It is a practical choice for a vehicle audio upgrade when paired with correctly matched speakers, appropriate wiring, and an externally fused power connection.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour-Channel Output:\u003c\/strong\u003e Powers up to four speakers or supports bridged channel pairs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuper D-Class Topology:\u003c\/strong\u003e Full-range amplifier design focused on efficient power delivery.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBridgeable Channels:\u003c\/strong\u003e Delivers up to 2 x 400 watts at 4 ohms.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccu-Cross Filtering:\u003c\/strong\u003e Adjustable crossover settings help match output to connected speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Level Inputs:\u003c\/strong\u003e Supports connection to compatible factory-style speaker outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto Turn-On:\u003c\/strong\u003e Signal sensing can eliminate a remote-wire connection in compatible systems.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe A800.4D has a black compact chassis with a heavy-duty aluminum alloy heat sink, Ultra-Fi MOSFET output devices, and surface-mount internal construction.
