This VEVOR subwoofer bass package combines a dual 12-inch loaded enclosure with a separate external amplifier to deliver strong, immersive low-end performance in your vehicle. With 1200W RMS output and a 30–200 Hz frequency range, it helps fill in the bass missing from many factory sound systems. The amp includes adjustable controls (GAIN, LPF, PHASE, and Bass Boost) so you can dial in the sound to your preference. Designed for broad compatibility, it can work with factory or aftermarket head units, including setups without RCA outputs via a high-to-low converter. The enclosure construction and separate amp design support consistent output and clearer sound during extended listening.
