Description

If you do not have a lot of space in your car, a hideaway car subwoofer is your best option. This is usually a compact woofer with a slim form factor that allows it to be easily tucked under a seat. One of the best things about the under-seat car subwoofer is that it is very easy to install by almost anyone. Additionally, since it uses the space under the seat as an enclosure, it produces a deeper and even more powerful bass which compensates for its small size. The MB Quart Compact Sub is a popular solution for car owners on a budget that doesn't want to sacrifice sound quality . This model is an all- inclusive solution that packs a powerful bass. The cone is at 8 inches or 10 inches, and since the cone is small, it vibrates more and produces a punchy bass that is harmonious. Additionally, this under seat subwoofer can be remotely controlled for better convenience. Also on the upside, if you like tweaking your music then there is a number of customizations that you can do. It still sounds good at default setting for those who simply do not care about bass tuning. Additionally, there are many audio customizations that can be performed in this woofer. People who care how their bass sound will like this unit very much. As almost expected from a company like MB Quart, it is equipped with advanced circuits that help protect and prolong its lifespan. Circuits like overheat protection or reverse polarity can come in handy for those who like to listen to their music loud. As for the built quality, it is excellent. The whole unit is made of aluminum that does a good job absorbing heat and preventing the woofer from overheating during extended usage at loud volumes. Moreover, the front metal grille adds protection to the diaphragm and help to extend the life of the woofer. Overall, this is a excellent model, and this hideaway subwoofer from MB Quart is durable, offers many audio customizations and very easy to install.

  • Fill in Base
I bought this powered sub woofer to fill in the base my JBL speakers were missing, now don't get me wrong I could turn the base up to my door speakers but the vibrating noise was driving me insane from my door panel. The powered sub was going under my driver seat and the plan was to run all the wiring under the carpet and the trim which worked out well. After about a month of using the sub I am really happy with the quality of sound it provides, the remote included is a nice feature but if you are looking for head numbing base this is not for you. So far I am happy with the sub and how simple it was to install in my 2019 Tacoma. ... show more

  • Great little sub
It impressed me.. I didn't think anything of it good little unit. The price is more than fair. As good amplifiers can already start at $200. I am pleased by this little sub.

  • Great price for a name brand
For about the same price or close to these no name brands everywhere in the same category. I honestly say it can't be beat for the price range. These ain't no window rattling deep 12's. What these are good for are older cars trucks etc that never came with a factory sub. Hits slightly harder when turned up over my Infiniti's with factory Bose subwoofers. Again good for that notes of bass you want to hear instead of all vocals and highs with stock NO Sub vehicles. Very compact to fit under seats or in the truck in the corner etc out of way. Sure could've spent little more get a box with 2 10's or 12's and a amp but this is a simple daily and can use the trunk space. ... show more

  • Perfect For Our Application
We wanted a full range of sound with better lows but without the brain rattling that some sub installs can bring. It gives an excellent full range to our existing system and can highly recommend! You can fine tune it to your system for a real, full range of quality sound.

  • Sounds good but doesn't last!
Sounded good in my wife's jeep but just blew out under 2 years old.

  • Great value for $$ Impressed w power
I was genuinely impressed w how powerful the small speaker was. Not the cleanest Bass sound, but very powerful. I’m quite pleased. Installed it under the seat of my Ford Ranger and it dramatically enhanced the sound quality. Louder than I thought it would be- and it fit under the seat and still allowed full movement of the seat. Highly recommended. ... show more

  • Rounds out the sound for new stereo
I purchased this unit because I was replacing the stereo and door speakers in my 95 Tacoma. Without the added bass the 60’s & 70’s Rock & Roll I normally listen to was lacking. The truck is old and has a lot of wind noise. Duh it’s 28 years old. Adding more bass provided the low end punch I was missing. I recommend this unit for anyone who wants crisp lows to come through an imperfect environment. ... show more
