NVX QBSTA - Customer Ratings & Reviews

Love it just what I needed !

I took a chance on this spare tire subwoofer thinking well I'll only get a little bass probably nothing too serious. Wow is all I can say it shakes the rear view mirror pretty good and it jars the outside panels on the back of my 21 Nissan Murano and the bass travels all the way to the windshield wipers had to place my hand on one to get it to quit vibrating the front 10 outta 10 at least for me I'm a old school bass head and this has satisfied me for a daily driver and not compromising any space.

Item is fantastic, only one thing was missing...

The QBSTA is amazing, it is as shallow as a competitor's shallow version but handles more power and adds plenty of bass. The controls are on top which makes it easy to tune. The auto turn-on feature works perfectly with the high-level speaker inputs. We needed a 10mm bolt to attach it to the car; the manual said it should be in the box, but the unit only had an 8mm bolt that came with it. Once we got that squared away, the unit bolted down properly and the bass was coupled to the vehicle frame like it should be. Great product, but check for all the mounting hardware

This thing outperforms my expectations

I am a bit out an audiophile. Always upgrade stereo and speakers in my older vehicles. This one in particular is an 87' 944 turbo Porsche. I didn't expect it to be this good out of the box to be honest. I expected half this...the weight and build quality are better than expected. I hooked it up and tested it out this evening for the first time and I am honestly blown away. It hits nice and clean. 3x louder than expected. I haven't turned it up or tuned it from factory setting and it seems like I need to slightly turn it down already. Thing is amazing for the money. I will probably put one of these in everything from now on depending if it lasts...but I feel like it will do great.
I did use OFC 8g wiring on a 40 amp breaker so I went a little more substantial than was needed but I am happy I did. The other reviews on this product don't seem to tell the story. 100% satisfied especially for the cost. I simply cannot believe it is this clear and deep. Buy with confidence and use good wire.

Sounds good in my 19 golf r

Hello everyone. I bought this sub and put it in my 19 Golf R. I had a shop install it. After a few small adjustments. All I can say is wow. It sounds really good in the car. Deeper bass that has decent resonance. It shakes my little car a little bit, but the bass is great. I had a factory fender subwoofer and it lacked in everything which is why I bought this sub. It fit under the floor on the hatch of my car. Definitely worth it. Can’t comment on the longevity yet though. Nvx has been great for me. The last 3 subwoofers I’ve had have been Nvx and I wouldn’t trade them for anything.

b b b bass

it took a cpl days to install because of work, but oh man ! once I did finish it I was literally blown away . this 11 inch sub sounds better than 2 10s in a box. once I padded my license plate it's awesome. I cannot believe the sound this little dude puts out . I haven't even bothered adjusting settings past low level it's just too much power the built in amp would probably blow this speaker right out of the wheel well. Highly impressed keep up the amazing work and I highly recommend this to anyone with limited space vehicles . I put mine in a Benz 350glk 4matic and I let my coworker get in too check it out and I cranked old school bass mekanik. the look on his face was priceless when it hit the super lows . love it

best choice for this style bar none

i went with this one first for the price, then it having much more power than other options that are twice the price.

the install for the speaker fit perfectly in my 2024 mazda 3 turbo hatchback, i even reused the original bolt that replaced my bose sub that came with the car.

the DP switch, that you need for auto detect, wasnt set by default so i went a little mad trying to figure out why the speaker wouldnt power on. so if you have that issue check to see if its set to DP.

also this think kicks! the bass is a huge improvement!

This sub is great

This sub is very powerful and clear. I've ran dual 12 kickers, hiphonic and nvx ported and sealed, and this sub holds its own. Definitely get your money's worth, especially with sound deadening

Very easy install and sounds great! Sounds amazing for essentially a free air space subwoofer!

The best bang for your buck

I really like this discreet and hidden away in the spare tire area subwoofer. I installed this subwoofer in my 2025 VW GTI which comes with a Herman Kardon sound system and sub. The stock sub is basic and lackluster. I bought this one and installed it myself over the weekend and it exceeded my expectations. It shakes my rear view mirror and bass that you can feel. It works perfect in my hatchback. Worth every penny. This is the most powerful spare tire sub on the market. Highly recommend it.

Surprising output

My expectations were fairly low for this unit, I have a factory JBL stereo in a 26 year old vehicle that was well ahead of its time and still sounds pretty decent, just had no low end due to no actual woofer.

I honestly thought the highs would overcome the lows still but this little sub keeps up really well. Plays lower then expected, and has a good amount of rumble.

This completes any factory systems that are missing a woofer

This would upgrade any system that comes with a factory woofer.

Durability is untold. Time will tell.
