RockvilleWheel of BASS 8" 500W Powered Car Subwoofer, 4 Ohm, Slim Design, Easy Install, Remote Bass Knob, for Trucks and Cars

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.

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

Put this in my 2018 Sierra Crew Cab, biggest issue (as always) Is getting power through the firewall (need your own 10G or heavier line...I used 8G).Once connected and past the initial issue of protect light (reseating cables addressed it) it powered on and once phase, gain and frequency set it was noticeably better than stock door speakers.The only complaint I have is that the remote nob doesn't make any audible difference in the level. I've got power to it but it doesn't seem to affect it. No big deal as the head units bass control controls it fine...just my reason for a stat off.Good little banger for 100 bux

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.

Compact and easy to install. Problem is, it gives you minimal bass. Was not expecting booming bass like a full range sub but it is not worth it for what you get out of it.

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.

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.

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.
