Review: 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
Review: 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.

A: Yes it will. I have one in a can am maverick.  It sounds great

**Q: Will this work in an EV vehicle?**
A: As long as you can feed it 12V and have an audio output for it, it should work fine.

**Q: Will this work with a 12v battery ?**
A: Will work with any standard vehicle battery

**Q: Is there a warranty and if so how long is it?
Does it come with any wiring? The high level inputs and power both look like they need specific plugs.**
A: The warranty is 1 year through Rockville. The product came with all plugs necessary to connect to my Sony head unit. It's a great product that works well in my Toyota Land Cruiser. The wired remote knob gives me full control to easily disk down the bass if I need to. Big bass in a small package.

### ⭐⭐⭐⭐ About equivalent in bass to upgrading to some decent 6x9s.
*by M***S on December 24, 2022*

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.
