12 inch audio speaker enclosure with built-in amp.
Really very simple and easy if remotely handy and understand basic electricity, wiring, and automotive audio. Strongly suggest buying additional secondary grilled speaker cover and replacing factory sad speaker protector bars. Very pleased with overall item. Drastically enhanced my audio sound while keeping me out of trouble with the neighbors. ... show more

WOW this thing hits!!!
Ok 1st off I have a 05 RAV4 with factory speakers, so a small SUV and this is almost too much bass! I was so close to getting the dual 12” version and I’m glad I didn’t. So if got a small car and you want to do hood rat things on a budget this is the perfect fit for you! Turn the bass controller down and everything is nice and balanced. I have no regrets ... show more

Buyers Beware! Steer Clear. Zero Stars. Sub defective after 3 days.
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 ... show more

Speaker ducks, box and amplifier are good.
Ok, we have bought two of these over the last few years. Both speakers blew within a week. The box itself, amplifier, and design isn't bad. So basically your paying for the box snd amplifier. Then do yourself s favor and buy another 12" low profile speaker and enjoy. Good design, good bass, with Rockville hardware and 3rd party speaker. We chose a pioneer lo profile 1500 watt sub snd boy oh boy. Worth it! ... show more

I put this in my wrangler and it still bumps with the top off going down the freeway...

This thing is awesome!
It was a little bigger than I expected even after looking at the dimensions before buying it. Totally worth it tho and not bad for the performance. It THUMPS and is super clear. Hooking up was easy as I was upgrading from a Dual Powered 10" sub in my truck. Had to take up the passenger back seat in my 01 Ram 1500, but it doesn't get used anyhow. The clarity, depth, and loudness is AMAZING!!!!! Would totally recommend getting this system for any vehicle. It won't win any competitions, but if you want to add alot of bass and are on a budget, this is the system for you!!!!!! ... show more
