Strikingly Powerful, Tight, Crisp Bass

The NVX QBUS8v2 is a phenomenal exemplification of the best thing modern technology offers us - freedom. Freedom to roam, to communicate, and in our case, to enjoy the depth and richness of your music without adding bulky amplifiers and subwoofer enclosures. We realize there are people who aren't quite satisfied with a dull, lifeless factory system, but also don't care to set off car alarms every time they turn the stereo up. It was with this customer in mind that the QBUS8v2 was born. What separates the QBUS from other compact bass solutions is the acoustic performance and quality of the construction. While it won't shake your rear view mirror off, the low-end response of the QBUS is perhaps best described as strikingly powerful; the tight, crisp bass carries a strong presence without overpowering the more delicate frequencies. The included bass control knob allows you to quickly adjust the level of bass for different types of music.

Rugged Aluminum Chassis

The beautiful thing about the QBUS8v2 is that it's a fully contained subwoofer system, consisting of an ultra-durable woven fiberglass 8” woofer driven by a highly efficient class D amplifier. These components are housed in a rugged aluminum chassis, specifically designed to offer incredible strength and protection while effectively dissipating heat. Best of all, the housing is less than 10” wide by 14” long, giving the QBUS a footprint about the size of a legal pad. At about 2.5” thick, it slides easily under the seat of most sedans and SUVs. If you have room for a book, you have room for bass.

Easy to Install & Enjoyable to Use

While spectacular sound quality and compact, rugged construction might be enough for some, we at NVX believe in designing products that are as easy to install as they are enjoyable to use. The QBUS8v2 features speaker-level inputs with signal sensing automatic turn-on, allowing you to tap directly into your existing speaker wire without running RCA and remote wires. Adjustable input sensitivity, crossover, phase and bass boost controls make it easy to tune the sound to your preference. Silver-plated RCA connections and wire terminals ensure a tight connection with maximum conductivity.

  1. Are Under the Seat Subwoofers Any Good? Are Under the Seat Subwoofers Any Good? Historically, subwoofers have been enclosed in massive boxes that take up your entire trunk or hatch space; now, many brands are attempting to appeal to larger audiences by supplying more compact options such as under the seat subwoofers. But, are they really any good?
