JBL - BASSPRO 8" Single-Voice-Coil Loaded Subwoofer Enclosure with Integrated Amp - Black

I had a little trouble finding the proper 12v remote wire on my head unit. Other than that this little thing packs a punch. The lows can be adjusted to your liking and it fits perfectly under most car seats. I have a Ford econoline so i have it in between the driver and passenger seats. It rocks best with rap music and funk but I've tested it with 60's and 70's rock as well as classical and the included remote is essential when control the bass. I recommend it

I have an acura ilx. It doesn't come with great speakers and didn't have a sub too! I did upgrade my front door speakers with the JBL GX628 which helped improve the sound and the bass but it was still lacking the oomf that we all want. Honestly, this subwoofer does the job. Is it comparable to a 2k system, no, but for what it does honestly I'm satisfied. Clean bass, not muddy and not too harsh too! It made me a happy customer and I'd recommend it for anyone who has a car and doesn't have a fancy speaker system. It's really great

This is a underwear subwoofer that I have mounted in the trunk space of a BMW x4 right behind the 2nd row seats. It doesn’t sound like I have a 12 but it does sound too good to be true from its size. My vehicle has the upgraded Harmon/Kardon sound system and this sub adds very much to the over all sounds and sounds like it’s from the factory. Very impressed

2018 Double Cab Tacoma. This does not compete with my 12" Rockford in a Belva 1.8cbu ported box....obviously. HOWEVER I was pleasantly surprised at the performance this can throw out. Install fits nicely under my driver seat. And if you don't know Tacoma seats are LOW. I wish I could easily access the output to try and match the voltage going to the sub. But the adjustments that are on it allow you to tune by ear essentially to a good level. It has an overcurrent protection so you can't go balls to the wall and blow it apart. Thumbs up for that. I have 2 6x9, 2 6.5' and kicker tweeters form a 2020 Subaru STI (Tacoma thing). Powered by a Sony XG amp. And a Sony headunit. Makes a wonderful addition to my sound system. Bottom line if you want window breaking bass keep looking. BUT if you want decent bass that fills the gap your stock or aftermarket 3 ways are lacking in a small car or truck id give this a shot.

I purchased this subwoofer for a 2020 Honda Civic Si Coupe that came with the 10 speaker setup with factory sub. It has very lacking bass from the factory, like pretty much all Hondas. The Coupe has a very small trunk so I did not wish to give up trunk space for a traditional sub. This fit perfectly under the driver seat without limiting rear passenger foot room, and is slim enough that it clears the bottom of the seat even at the lowest setting, unlike the Kicker Hideaway. The first two days I regretted the install as it didn't sound as full, but after a few days, it broke in and was noticeably better and I am now very happy with it. This is definitely not for someone looking for traditional heavy subwoofer bass. This sub will fill in the missing low end and for many songs can actually be impressively strong. However certain rap songs put out too much bass and the sub has a built in safeguard that cuts the bass output to keep it from blowing. Even when this happens, it is still stronger than factory, but some may not be happy. I found that hooking it up to the factory sub output and leaving the gain at a lower setting caused this to rarely happen except on a few songs (out of 1,300 songs on my iPhone I noticed it with only 3 rap songs that had a very low frequency that was sustained throughout the song), and overall provided a very full sound that was even around the cabin. Unlike some under-seat subs, this can be felt pretty equally in the passenger seat as in the driver seat. The build quality is very good and provides an overall very good sound to complete a nice setup without really tearing apart the car's factory sound system. It is definitely worth tuning and testing it repeatedly over the course of a few days to really reach the sweet spot, as doing that made a big difference for me.
