Frequently Asked Questions (FAQ)


If using the high-level input, ensure the Auto Turn-on switch is set to "DC." If the sub still doesn't wake up, your factory system's signal may be too weak. Run a dedicated Remote (REM) wire to a switched 12V ignition source instead.
This is a sign of voltage drop. Check the 12V power and ground connections. The ground must be secured to bare, unpainted metal. A loose or painted ground terminal causes the amp to starve for current and shut down for safety.
This is likely Signal Clipping. Turn the "Gain" and "Bass Boost" down. If the input signal is too high, the internal amplifier will overheat and distort. Setting the gain correctly ensures the sub runs cool and prevents the voice coil from burning.
For maximum output, place the unit in a corner of the trunk or under a seat with the woofer facing a hard surface. Ensure the cooling fins are not covered by carpet or mats, as airflow is required to prevent thermal shutdown.
The remote is a Level control, not a power switch. If your head unit's subwoofer output is turned off or set very low in the "Settings" menu, the remote will have no signal to increase. Ensure your radio's sub-out is active first.

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

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.

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.

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!

Sounds great but missing a critical feature!

Install was pretty easy and straightforward and it sounds pretty damn good in my Corolla Hatchback. One thing I would have liked though is either a clip light for setting the gain or at least an exposed area to match gain with an Oscilloscope or Multimeter . Even with this thing tightened down hard it vibrates too much to accurately set it by ear in my opinion.

2018 malibu nvx sub add on

I love this little spare tire Amplified subwoofer, I put this in my 2018 Malibu LT although it wouldn't fit on top of my spare tire I was able to bolt it down to the bottom of the spare tire area and the spare tire was able to fit on top of it so now it's really hidden. Best money I've ever spent I'm 51 years old and I wanted to add some extra Bass and this was perfect for that I can still save some of my hearing. If you're looking for some base that's not ear blowing then this is perfect for your addition, I also added it to my Bose system that was in my car and it worked out great
