JBL Bass Pro SL2 8'' Underseat Subwoofer Boombox

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.

I bought the powered JBL sub for 2 reasons:1- I could hide it under my seat.2- It’s a JBLInstallation 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.

Decent for the money.

Nice great sound bass perfect for my car.

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.

Don’t be afraid to use this jbl. I had a kicker 10 inch before and never cared for it. Even though this is only a 8 inch powered sub it really has a quality sound.

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.

Worst subwoofer. I never thought jbl provide like this cheap build subwoofer. Its waste of money
