  • SLIM DESIGN FITS ANYWHERE: At only 3.15" tall, this subwoofer slides under seats or fits in tight trunk spaces, delivering powerful bass without sacrificing room. Ideal for trucks, cars, or compact vehicles needing a space-saving audio solution.
  • POWERFUL 500W BASS OUTPUT: With 500W peak power and 125W RMS, the WHEEL OF BASS produces deep, clean bass. Adjustable bass boost (0-12dB @ 45Hz) lets you fine-tune sound for music genres like hip-hop, rock, or EDM.
  • EASY INSTALLATION: Built-in amplifier and high/low-level inputs simplify wiring. Auto turn-on technology activates the sub with your audio signal, making setup quick for factory or aftermarket systems. Includes mounting hardware.

    • Just to add some extra bass, Honestly over-all good product
I bought it for my 2017 Silverado under the rear seat on the center hub and to be honest I wasn’t expecting anything crazy out of it but it has out done my expectations I’ve had it for about 7 month with no problems, I keep it just under half volume on the bass nob and it does damn good, install was straight forward and wiring wasn’t difficult even with stock head unit, Rockville is a good brand ... show more

    • Great performance for the price.
This one won’t win you any stereo competitions but it sure will make your sound fatter and thumpier (if that is a word?) It would not fit under the front seat of my F 250 but fit nicely under the rear seat. It made my low priced Alpine stereo sound a hundred times better! I highly recommend this unit. ... show more

    • Excellent If
The wheel of base works great, it was an easy install. (Didn’t come with control knob cord but Rockville helped me out). It is excellent in a 2 Dr Jeep JK and rounds out the sound really well. Like others have said, it’s not a box sub but I wasn’t looking for that level. It does what I want it to do and it’s held up for a month already. ... show more

    • About equivalent in bass to upgrading to some decent 6x9s.
If you want curb pounding bass... or even decent bass that you can hear coming up the street, this is not for you. If you have factory speakers that have 0 bass even after upgrading your head unit like me, and just want to fill out the bottom end of your sound, this will do the trick. My enclave has nothing but 4" door speakers, and terribly cheap ones at that. The factory stereo is pathetic, not even loud enough to hear with the windows down. I upgraded to a kenwood touchscreen, and the volume levels were much better but those door speakers simply don't put out any bass. Added a Rockville Wheel of Bass under the front passenger seat, tapped into the speaker wires behind the kick plate, and the battery is right there too in front of the 2nd row passenger seat in the floor. Everything is hidden, no visible wires, and it rounded out the bottom of my stereo nicely. My enclave doesn't bump, but inside sounds great. Enough bass to slightly rattle a few things in the car and kind of feel in your chest, but not overpowering. As long as you're only looking to fill in the lower frequencies in your system, the wheel of bass is great choice. ... show more

    • Great compact upgrade
Pleasantly surprised with the extra kick this gives. Don't expect your mirrors to rattle off but this really rounds out a stock system nicely. Good bass for the price and size. 90% of your average users will be super happy with it. The other 10% are people that probably just need to upgrade to a box and sub combo for big bass. If you want something that takes up next to zero space and adds way more bass than stock, this is a great option. ... show more

    • Did not last
Installed this in a UTV. Was very satisfied with the sound and size of the unit. It is mounted in a clean and dry location. After only about 4 months (maybe 6 rides) it has started messing up. Rough terrain must have messed it up I guess. After about 5 minute it just pulses. It does this even if you stop the music or unplug the inputs. It will do it until the power is shut off. I have reached out to Rockville and they want me to ship it back on my dime. Then if they don't find any reason not to honor their warranty (including return shipping damage) they will repair it if possible. What a PIA. I mean just send a new one for crying out loud. It's like a hundred dollar speaker. I will not be buying another Rockville product. ... show more

    • Pleasantly Surprised
I purchased this because my son wanted to add some extra bass to the factory system in his 2013 Ford Fusion. I've never been a fan of trunk-rattling subwoofers, but thought this under-seat model would be enough that he could hear/feel that extra low end and get a bit more out of his music. I was a bit skeptical seeing as how compact this model is, but we were both very surprised. Like other reviewers have said, don't expect this to wake up the neighbors. However, it's enough to round out the lower end of the sound spectrum and take some strain off of your woofers. Setup was fairly simple once we figured the best way to get through the firewall and wire it to the battery. The onboard controls make it a cinch to dial in the right frequency range, volume, and gain to complement the factory speakers. Our next step is to attach some passive crossovers to his door speakers and let the Wheel of Bass do the heavy lifting. ... show more
