VIBE Audio PowerBox 650.1M Compact Class D Mono Car Amplifier 650W RMS Subwoofer Amplifier High Level Input

The PowerBox 650.1M is a high-efficiency Class D mono amplifier engineered specifically for subwoofer duty — delivering serious power in a compact, discreet package that fits where conventional amplifiers simply won't. Built around VIBE's iconic black and red signature design, the 650.1M produces 650W RMS at 1 ohm with four levels of circuit protection and robust internal components, giving you confidence that your system will perform at its best day after day. The efficient Class D architecture maximises output while keeping power draw to a minimum — so you get more bass without draining your vehicle's electrical system. High-quality internal MOSFETs process the input signal digitally, amplifying it with exceptional clarity and minimal distortion. A built-in low-pass filter (50-250Hz) eliminates unwanted higher frequencies for a cleaner, tighter bass output from your subwoofer, while the subsonic filter (15-40Hz) cuts infrasonic noise that wastes power without contributing to audible bass. A Bass Boost control lets you dial in additional low-end impact, and the included remote gain control allows continuous volume adjustment from the front of the vehicle — perfect for on-the-fly tuning. RCA inputs with a 0.2-10V input range ensure compatibility with a wide range of head units, and the 0° or 180° phase adjustment allows precise integration with your existing speakers. Whether you're building a dedicated subwoofer stage or upgrading an existing system, the PowerBox 650.1M delivers the power, control, and reliability to get the most from your subwoofer.
