Features 5
- 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.

Amazing sound super compact.
Size: 150W RMS 8" Ported
Amazing sound for a small compact unit. Can’t get an easier setup!! Was skeptical with getting an 8” sub but this did not disappoint. I was only looking to add low range sound to my music and make the drive to work more enjoyable, while fitting under my 2021 Colorado back seat. But it definitely out performs. And can’t beat the value.

Great sub
Size: 150W RMS 8" Ported
Sounds great. I bought the 8” model. Overly surprised how hard it hits. Well worth the money. Hopefully it lasts for a long time

Fantastic amp sub combo!
Size: 150W RMS 8" Ported
First off let me say this is my third NVX product and I would compare them to alpine products for a much more affordable price. This NVX sub amp combo was super easy to install and sounds great! If you are looking to round out the over all sound of your vehicle (not rattle doors) then this will work great. It’s a big improvement to my 2012 F150. One thing I didn’t understand was the on off switch on the amp, but you will want to leave it off if you have a remote wire from your stereo to the REM input on the amp. Tuning this wass super easy with built in knobs. It took me about 1 hour to install everything. Overall very happy!

Perfect
Size: 150W RMS 8" Ported
I just need it to fill n some notes. It’s more of a mid bass woofer then an actual sub. I’m very content

Disconnected port, easy fix and sounds great after.
Size: 150W RMS 8" Ported
Is great….after I fixed the port that was disconnected. Was a pretty easy fix, but a shame to have to do that with a new product.

(Update) What I Needed
Size: 150W RMS 8" Ported
Update: Still Very Happy With This And Have Had No Issues With This Little Sub What So Ever. Really Glad I Purchased! I Purchased (Not A Vine Product) And Installed Last Weekend. I Will Say if You Are Wanting To Add A Little Low End To Your System But Short On Room, It's Pretty Solid. If You Want Tons Of Bass, Like Most Will Tell You, This Probably Isn't For You. I Will Say I Wouldn't Crank The Bass Boost And Gain To The 11's, It May Have/Need A Break In Period But Doesn't Specify In The Manual. I Am Running It At Less Than 1/2 On The Gain And No Bass Boost At The Moment. For The Money I Am Pretty Impressed And Happy With It, I Will Do An Update In The Next Few Weeks.
