Wow! First underseat subwoofer

I haven't owned an underseat sub before but this one is almost too loud! I turned it down of course, but it definitely gave the rumble and bass i was looking for

Not for everyone

First of all, I purchased this with low expectations. I recently got a new truck and wanted to add some extra bass to the factory Bose system it came with without doing a full system build. I chose this one based on price, history with NVX products, reading reviews on other brands, and the fact this one has a port where others do not. I will say I am not surprised that this really didn't add much more bass to my Bose system. I am used to doing the whole sub + box + amp build in my vehicles so compared to that this really lacks. If you are short on space and can fit a shallow sub or a 6.5" you will get more bass from those than with this. HOWEVER, I decided to move it to my daughter's car (Mazda 3) under her seat since she does not have a premium factory system and it did greatly improve what she had. The best way to sum this up is if you have factory premium sound this will not do much, if you're used to running normal sub builds this will disappoint you BUT if you have a basic factory audio and just want bass that compares to a premium factory system and can fit this in the cab of your vehicle then this is the best one for the money. 2 stars for me, 4 stars for my daughter, overall 3 stars.

Erik added a comment:
"Mr. "Seal Team Rick" does not understand that the lack of bass or good sound has nothing to do with the NVX subwoofer, but instead it's because of the automatic equalizer built into the crappy Bose system (or he's a terrible installer). As Mr. Rick turns up his volume, the Bose system rolls off (turns down) the bass, protecting their crappy $2 speakers. Because of that factory EQ, any add-on subwoofer will sound like crap unless a compensation circuit (like an AC LC2i or JL Fix) is put in line with the input signal.
I would suggest you remove this review as it's inaccurate and not fairly representing NVX's capabilities.
Just my 2 cents :)

I was skeptical… but pleasantly impressed

I am really surprised on the lack of reviews on this product. For such a great price I am really impressed. I was looking for an affordable compact sub for my 01 Vette. I took a shot in the dark with this and I couldn’t be happier.
Let me tell you what you get. An amazing 10” sub that’s so compact it’s impressive. Well balanced lows that will round out your system to create a perfect harmony for almost all music types. From Country, Classic rock and even rap like Dr. Dre.
Want you don’t get, a penetrating boom that can be heard at distance. No mirror shaking either.
I’d recommend this sub for anyone with a hatchback or truck cab.
This sub is just a great value!

Not bad for the size

Sounds decent would be great for under a truck seat, car seats may be too low to use this. I liked the internal amplified feature of this. It’s not super hard hitting, but it’s decent for the size.

Great Value

Everything about this sub has been better than what I expected,
I gave it a 3 on durability because the 1st on went bad with in the first 2 weeks, so far the replacement one has been great!
Update 1/5/23 2nd one went bad on the 3rd speaker now, do not buy this thing!
For the value I am more than impressed what you get out of such a small compact sub.

Perfect for limited space

Made an old 87 BMW convertible's system sound great. Factory speaker locations are very shallow so you're only able to get minimal bass even upgrading to new speakers (ended up with Alpine coaxials in rear, DB Drive coaxials in front kick panels, and NVX tweeters in factory sail panels).

Found this NVX because I didn't want to hear my trunk rattling like I used to do 20 years ago with a huge box, subs, and amp taking up a ton of space. Placed it in the passenger side floorboard up under the dash. Don't expect the same kind of bass from a monster sub in a big box but for a strong presence when you only have a little space available, it works great. This thing surprised me and really rounded out the overall sound quality of my simple setup in my old car.

Might throw one in my son's 530i under a seat. For $149 you'd be hard pressed to find a better value for a sub/amp combo with 200W RMS and 500W Peak Power. The small port is a really nice touch that I hadn't seen on these types of setups.

Just Day 1 with this sub so I can't speak on durability yet but I definitely look forward to cruising in my classic this weekend with the top down as I continue restoring it.
