- Rockville Wheel of BASS 8 Inch Slim Under-Seat Powered Truck/Car Subwoofer | 500W Peak, 125W RMS, Cast Aluminum, Metal Bass Knob, Auto Turn-On, High/Low Level Inputs, MOSFET

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

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.

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.

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.

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.

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.

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.

After 4 try’s this is the ONLY one that fit under my passenger seat. I can’t believe how much bass it puts out. It can shake the mirrors or with the remote it can be turned down to a lower level. I didn’t want a big box and no one knows it’s there so it won’t get stolen. Anyone with a JK will love this tiny amp and sub. I took the seat out to install and relocated the two wires under the seat with an L bracket from Walmart. Recommend it!!!!

PERFECT FIT!! IM SUPER EXCITED! I am installing this into my ebike and so far everything is fitting just perfect! Just waiting for rhe rest of the components I bought to come in mail and I'll then upload a video review. Thanks Amazon!

Good value for money. Will highly recommend. Quantity of bass is beyond my expectation. You have to buy extra wire for as the wires that came with the set is short. Overall well built. Does exactly what it says.

Works great and wires up nicely on my 2013 Acura Ilx. Only problem I’ve encountered is the connections to the; power, ground and accessory is too close together and did not stay on nicely. I had to add ferrels and try to space them out. One time the accessory wire and power wire touched and blew the fuse to my stereo and the sub. At least nothing major broke.
