Does what it was meant to do!
I bought the powered JBL sub for 2 reasons: 1- I could hide it under my seat. 2- It’s a JBL Installation wasn’t that difficult, there is enough information out there to figure out installation on any vehicle. Most of the negative feedback I read when researching which sub I should buy talked about the sub not hitting hard enough or it made little or no difference to the existing system. I think the right application of equipment like this is critical. I felt it was a good choice for me because it was going in a small Toyota pickup and I wasn’t looking for huge sustaining bass. I listen to a lot of rock and heavy metal and was looking for some kick drum thump and boost in frequencies below 120hz. This sub has a good amount of range but you’ve got to spend some time dialing it in. That’s not a bad thing, no sub sounds great just plugging it in. You have to listen and adjust, listen and adjust. I have an Alpine head unit with a pretty decent eq section, everything had to be re calibrated. After listening to the new configuration for a couple of weeks and a total of 3-4 hours of tweaking it, I can honestly say it made a big difference to my system. Much cleaner bass frequencies, especially at higher volume levels. Kick drums you can feel and an all around way better mix. It really depends on what you need it to do. Giant bass will usually require a giant sub but if you’re looking to enhance an already good sounding system in a space that’s not too big, this may be the answer. It was definitely worth the try.

Great low end reinforcement for small size and flexible placement
It does a great job of reinforcing the low end, and allows you to lower the bass being sent to the factory speakers, by using your head unit’s EQ, while controlling the level of the sub with the remote knob. Its biggest benefit is the small size, which gives you a lot of placement flexibility, but at the cost of louder deep bass that a larger woofer and enclosure size would provide. It’s best application is as a low profile/hidden way to add more low end to your system, while decreasing the amount of low end sent to the factory speakers, thereby letting them be louder with less vibration or distortion.

Great sub with a small footprint
My son has a Honda Civic hatchback and wanted some more bass without losing space. This powered sub fit perfectly under the seat and hits hard. It was easy to install and connect to the factory head unit. Might need to get one for my car.

Excellent quality for the money!
Installation was extremely easy, and I trust JBL more than other brands when it comes to longevity. I ultimately upgraded to a larger speaker, but for what it costs this is hard to beat as a all-in-one package if your'e just looking to add a little more low-end to a factory stereo.

Moc w sam raz do Renault Clio 4, jeżeli głośnik był by słabszy wtedy był by nie dosyt, moc poniżej tych 125W nie miałaby sensu,tym bardziej. Polecam do małego auta,do dużego kupiłbym większy.

L'ho installato nella mia Mercedes SLK prima serie, posizionandolo strategicamente dietro al sedile del passeggero, e i risultati sono semplicemente eccezionali. La potenza e la qualità dei bassi prodotti da questo subwoofer sono impressionanti. Appena acceso l'impianto, si percepisce immediatamente la differenza: i bassi sono profondi, definiti e incredibilmente corposi. La cosa più sorprendente è la capacità di questo piccolo ma potente subwoofer di far letteralmente tremare il sedile con la sua spinta sonora. Nonostante le dimensioni compatte, perfette per l'installazione in un'auto sportiva come la SLK, il SL2 Bass Pro offre prestazioni da vero campione. La riproduzione delle frequenze basse è precisa e senza distorsioni, anche ad alti volumi. L'integrazione con il resto dell'impianto audio è eccellente, arricchendo l'esperienza d'ascolto senza mai sovrastare gli altri altoparlanti. Che si tratti di rock, elettronica o hip-hop, questo subwoofer JBL eleva notevolmente la qualità audio complessiva. In conclusione, per chi cerca un subwoofer potente, compatto e di alta qualità per la propria auto, il JBL SL2 Bass Pro è una scelta eccellente. La sua capacità di far vibrare il sedile con bassi profondi e potenti lo rende un must-have per gli audiofili che non vogliono compromessi

I've read in the reviews that it had cables etc to install it. But it doesn't come with cables. No ground/remote or battery cable. And for the ones who are amazed by the sound, I'm wondering if they ever had subwoofers before. Because I have and the sounds is, okay. Definitely not amazing. Installation is easy. The hardest part was finding a hole to get the battery cable from the battery to the inside of the car. You can feel the bass through the seat. It's nice that it comes with a remote to manage the bass so you can adjust it while driving instead of adjusting it on the subwoofer under your seat.
