Amplified Class-D Monoblock Subwoofer Power Amplifier (RMS 800W × 1CH)

Unleash deep, authoritative bass in your vehicle with the Amplified Class-D Monoblock Car Audio Power Amplifier (RMS 800W × 1CH). Engineered with a dedicated high-current Class-D digital switching topology, this monoblock amplifier delivers sustained sub-bass energy, high electrical efficiency, and low thermal output, making it capable of driving demanding single or dual subwoofer setups without draining your vehicle's charging system.

Built into a compact, heavy-duty extruded aluminum heatsink chassis, this amplifier installs neatly into tight trunk corners, under seats, or behind bakkie rear benches. Featuring 1-Ohm load stability, precision active low-pass filtering, an adjustable subsonic filter, and an included dash-mounted bass knob, it provides total command over your system's low-end frequency response.

Key Features & Benefits:

• High-Current Class-D Monoblock Architecture: Operates at over 85–90% efficiency, converting electrical power directly into dynamic low-frequency energy while drawing significantly less current and generating minimal ambient heat compared to older Class-AB designs.
• Continuous True 800W RMS Output: Delivers a true continuous 800 Watts RMS into a 1-Ohm load (approx. 500W RMS @ 2Ω / 300W RMS @ 4Ω), providing clean acoustic headroom to drive high-excursion subwoofers without clipping.
• 1-Ohm Impedance Stability: Designed to safely run low-impedance subwoofer wiring configurations (such as dual 4-ohm voice coils wired in parallel or dual 2-ohm coils wired down to 1 ohm).
• Adjustable Subsonic Filter (10Hz – 50Hz): Cuts off inaudible, power-robbing ultra-low frequencies that cause damaging cone over-excursion, which is especially critical for protecting drivers in vented/ported subwoofer enclosures.
• Precision Variable Low-Pass Crossover: Variable 40Hz–250Hz low-pass filter (LPF) allows precise frequency blending with your cabin door speakers, ensuring bass sounds tight, focused, and integrated into the soundstage.
• Onboard Bass Boost & Phase Control: Features an adjustable 0–12dB bass boost centered at 45Hz and a 0°–180° phase selector switch to correct acoustic cancellation between cabin speakers and trunk-mounted subwoofers.
• Wired Remote Dash Bass Knob Included: Mounts within easy reach of the driver, allowing real-time adjustment of subwoofer output level according to music track variations or passenger preference.
• Multi-Stage Protection Circuitry: Onboard microprocessor protection safeguards against thermal overheating, direct speaker short circuits, reverse polarity, and voltage surges/drops.
• Flexible Dual-Input Architecture: Equipped with low-level RCA pre-in/pre-out connections for aftermarket head units, alongside high-level speaker inputs for seamless factory radio integration.

Ideal Applications:

• High-Power Subwoofer Upgrades: The dedicated power stage for driving a heavy-duty single 10-inch, 12-inch, or 15-inch subwoofer, or a matched pair of dual subwoofers wired to 1 Ohm.
• Space-Restricted Vehicles & Bakkies: Compact footprint allows installation under driver/passenger seats, behind single-cab or double-cab rear seats, or inside shallow boot recesses.
• Factory Infotainment Sub Additions: Easily taps into factory audio systems via high-level inputs to add deep bass to an OEM screen setup without replacing the factory head unit.
