## Questions & Answers

**Q: Does this subwoofer really beat?**
A: I have it in my suburban and it travels nicely through that bus. Once it's broken in you'll be able to crank it higher and truly appreciate it

**Q: Can I use 10 gage wire?**
A: When I bought this sub I took it to my local installer and had them run the wiring because my Camaro has a ridiculous harness setup that I didn’t want to ruin. They did the work and it sounds great. I know that they did use the wire that came with the kit I got so there’s that. If your sub didn’t come

**Q: What  size  wire**
A: 8 gauge for the sub remote

**Q: What size power wire should I use with this?**

## Customer Reviews

### ⭐⭐⭐⭐⭐ Decent bass.
*by G***5 on June 22, 2025*

For what they are they offer decent bass. Not gonna shake the windows, but if you're looking to add just a little more bass to your system these work well.

### ⭐⭐⭐⭐⭐ Why r you waiting to buy this ..it's kicks butt
*by P***. on June 17, 2025*

Sounds amazing . Just added to my 17 JK

### ⭐ Buyers Beware! Steer Clear. Zero Stars. Sub defective after 3 days.
*by J***D on October 1, 2024*

The sub was installed and after 3 days it sounds like the cone is separating and rattling so bad that it just sounds terrible. After 3 days of back and forth they want me to foot the bill to send the sub back in for repairs. Shipping is not cheap. I now have buyers remorse. Buyers beware, go with another company, spend $30 to $50 dollars and steer clear of Rockville. See the actual response I received.Hi Jared, Thank you for contacting Audiosavings technical support. I'm sorry to hear the Rockville RVS12A we sent has a rattle in the center of the woofer. "Blown" refers to when an amplifier blows up a speaker, it usually catches on fire briefly, and smokes, when that happens. This sounds like a different malfunction. Our apologies for the issue! We have a warranty which allows you to send it in for repair. You would buy shipping from your carrier of choice to get it to us and from there we cover parts, labor, and the return shipping. If we can't repair it, we'll replace it. Would you like me to set this up? I’ll get started on the RMA (which is a return order so that our warehouse team can expect your shipment) Our apologies for this issue. Please let me know if you have any questions Thanks, James
