Description

Space Saver - The combination of a built-in 300W amplifier that powers the 8” subwoofer makes this ideal for spatially challenged vehicles.

Variable Low-Pass Filter - A low-pass filter is an electronic circuit that removes all the notes below the filter's frequency setting. You will use the low-pass filter to primarily keep high notes out of your subwoofer. Adjust it from 50-150 Hz to best fit your system.

Ease of installation - Takes either speaker wire (High-level) or RCA cable (low-level) inputs. This makes connecting the QBUS8P to your radio easier since it's compatible with both factory AND aftermarket units!

Automatic Turn-On - This circuit automatically turns the QBUS8P on whenever it senses an audio signal. This eliminates the need to run a remote turn on wire making installation a breeze.

Variable Bass Boost - Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.

Common questions about buying open-box and refurbished.

Why buy refurbished or open-box?

Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $63 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.

What's the difference between open-box and refurbished?

Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.

Why use OpenBoxFox?

Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for NVX products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.

Is it safe to buy refurbished?

Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
