This VEVOR subwoofer bass package combines a dual 12-inch loaded enclosure with a separate external amplifier and wiring kit to upgrade your vehicle’s low-end performance. Rated at 490W RMS with an 800W peak output, it’s designed to fill in deep bass from 30–200 Hz for a fuller, more immersive in-cabin sound. The separate amplifier helps manage heat and maintain clarity with THD ≤2% and SNR of 92 dB. Adjustable gain, LPF, phase, and bass boost controls let you dial in the response to your taste. It supports both factory and aftermarket head units, with an included high-to-low level converter for installs without RCA outputs.
