JBL do it again! Powerful
Amazing powerful bass from such a slim compact unit, I am used to large bass enclosures and am VERY into my music so this 100% gets the best rating. JBL at their best

Great Powerful Subwoof 250W peak
I can't find anywhere online that states anything than the rms value, but the peak is 250watt. It is surprising powerful and strong deep bass. In the boot of my Corsa D, its is quite powerful you can feel it in the seats, under the seat it feel like having a ported subwoofer of like 400 watt its really quite an impressive unit.

Good sound for the cost
Good sound for the cost. I have gone through 3 subwoofers and this one, so far is the best by far.
User
Nice
A decent snall sub. Do not expect massive bass but it does the job
User
JBL are the Best...
JBL are well known for their audio equipment, this is no exeption. perfect for placement under the seats and very powerful. pair this with an amp under the other seat to drive the x4 door speakers and x4 tweeters and you have an awesome setup.

Not extremely punchy
Good and compact

Seems great, but won’t last long
Thought this little sub was great! However only had it wired in since the first week in February (which was carried out by a professional audio installer) and the sub has completely given up working.

Mieści się pod fotelem Renault Clio 4, moc w sam raz,polecam
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.

Super Bass, empfehlenswert
Sehr zu empfehlen. Habe den Subwoofer in einen e46 Touring unter den Beifahrersitz gebaut. Passt wunderbar, man muss bei dem Auto nur drauf achten, dass man den Sitz nicht ganz runter macht. Kauft euch gleich ein Endstufen Kabelsatz dazu, da ist alles bei was man für den Einbau benötigt

It's okay
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.
