    • Very solid sub for the size and the price, add polyfill if you can.
I put this lil number in the trunk of my sedan and it doesn't take up the entire trunk which is really nice. I have it facing away from the driver seat. I mainly listen to metal so if you do too keep reading. It's plenty loud and that's good and all but It sounded kind a little blurry I couldn't really hear the separation between the kick notes which is not ideal **BUT** I was able to take the speaker cone off and put in about .75 lbs of polyfill and that made a MASSIVE difference in the clarity of the bass and I highly recommend you do the same. It was a pretty easy and cheap improvement to this sub making it so much nicer! ... 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

    • Awesome Sub
For the price and quality of this sub, it is the best you can get out there. Bass is great enough to shake your car but not wake the neighbors up. If it’s your first time doing an install, this is an excellent option, as there is a built in amp, making the job easier . I’ll be making an update on the sub as time goes on, but the first couple of days, it’s been a great experience and worth every dollar and more! ... show more

    • Rattles after about a year of use
Solid sub for the price but only for about a year. There’s a wall that separates the amp from the woofer that comes unglued after awhile, I have to re-glue it about every 3 months or else you get an unbearable rattling sound. The sub itself doesn’t hit very deep, it starts to really pick up around 45-50hz but can sound good for certain songs ... show more
