VEVOR 1-Channel Class D Monoblock Car Amplifier — 400W RMS (1Ω), 1/2/4Ω Stable, Remote Subwoofer Level Control, LPF, Bass Boost & Phase Shift

Power and purpose: This Class D monoblock from VEVOR supplies 400W RMS at 1Ω, engineered specifically for subwoofers to deliver deeper, more authoritative bass with very low total harmonic distortion and noise for clean output at high volumes. Compatibility: Works with most factory audio systems in sedans and pickups and accepts 1/2/4Ω loads with flexible wiring options. It pairs with 10-inch and 12-inch single or dual voice coil subwoofers. Remote control and tuning: A 16.4 ft cable connects the wired remote level controller so you can adjust bass from the driver's seat; the panel also provides a low pass filter, bass boost, and phase shift for pre-drive tone shaping. Installation and form factor: The compact footprint makes the amp easy to fit behind a rear seat or in a trunk, supporting simple DIY installation in tight spaces. Cooling and protection: An aluminum alloy chassis with ventilation holes enhances passive heat dissipation, while built-in temperature, overcurrent, and overvoltage protection with real-time status feedback keeps the unit operating safely.
