JBLBassPro SL2 Active Underseat Car Subwoofer with Built in Amplifier - Under Seat 8'' 125 Watt Power Amplifier

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.

Has good base set up in a 98 Chevy 1500 OBS under the seat and improved the sound quality a lot. If you have a single cab truck and want more base this is the best option.

Exelente product

Was expecting a little more bass but I’m happy with the sound.

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.

everything about this is great. i highly recommend

I would like to first off say that I am a lover of loud music. I have an older truck that I could only fit one very shallow sub box in. I thought this would be a great alternative because this item tucks nicely under the seat. Once I removed the old sub and rerouted the wires I began tuning. I was excited because it looks so nice and sleek. After testing and tuning, this sub is for someone who has very weak low range in a stock setup. My door speakers actually have more bass than this sub. I am very disappointed because I had only medium level expectations for this unit and it does not come close. I have a factory sub in my new truck and it is light years ahead of this unit. If you have a very weak system and need only a very minimal boost, this will work for you.

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.
