Rockville RVB12.1A 500W Active 12 Inch Car Subwoofer+Enclosure, Built-in Amplifier, Adjustable Crossover, Deep Bass, for Car Audio Enthusiasts

I have now owned this sub amp combo for 10 years. When I first hooked it up, I had a seperate amp not realizing it came with one. How could it be this cheap and have its own amp? I hooked it up to a 2f capacitor (I recommend at least 4, 8 is better) to ensure clean power delivery.. and it knocked my socks off. This is not a competition sub. But for music lovers that want clean bass and decent thump that won’t rattle your windows out, THIS thing delivers!! Highly recommended, still going strong after 10 years… I only have had to replace my capacitor due to it being underpowered and hard on my alternator.

This subwoofer is amazing! The bass that comes from this beast will shake the paint off of your car! jk.Thanks Rockville!!

It sounds good. It overheats after 3+ hrs of constant use. Let it cool down for a hour and you’re good for another 2 hrs before it overheats again. But bro… it smells like fish. Literal fish. Anytime i get in the car it smells a little fishy, but when you pop the trunk…you can smell it a lot. Most likely it’s the wires or internals burning from getting too hot, but in all honesty it sounds great. The fish smell bothers me enough to write this review and begin my search for a better option.

Great speaker so far super easy set up once you’ve run the wire through your car. Got some real power and thump! Average size fit perfect in my trunk.

We bought this speaker and were extremely happy at first. It was bought April 2020 in March 2021 it quit working so I contacted the seller followed all their requests for troubleshooting. I was informed that a would receive a new speaker I paid shipping to ship it back to them it was at a discounted rate. When I received the speaker back it was the exact same one I sent them and no repairs had been done. I took it to an audio shop here where I live to be told that it was not working. I did this to make sure it wasnt me missing something here. So I do not recommend buying from this company. I also emailed them 2 days ago and let them I received the speaker and everything I did I also informed them to let them know I was going to leave a bad review thinking they might respond to give them a chance to make things right and I havent heard / received anything from them. I know they read the email sent because I track my emails.

It does smell a bit but bumps good for a basic everyday drive car

First things first, THIS IS BOT A HOGH WUALITY SUBWOOFER. You cannot get a high quality one or expect a high quality one for $100 (what I paid at the time). My expectation for this unit was bass, not good bass, just bass. I like car audio and I’m generally an audiophile, but I don’t have hundreds or thousands of dollars to spend on a good setup. For the price, this subwoofer is pretty good. It’s average. It gets you pretty loud bass, and fills your ears, but it takes a hell of a lot of work to actually tune it to sound the way you want it to. It sounded great for about a week, I had it behind my seat in my 4 runner, but moved it to the back and the sound quality diminished so I moved it back. I didn’t change a thing or damage the sub, but when I moved it. Somehow in the process it developed a rattle. This rattle sounds horrible, and it’s honestly hard to listen to, I have to keep the bass really low for it not to rattle, basically off. So would I reccomend this unit? No, it’s not worth the money you spend, save up another $100-200 and buy a single scar audio subwoofer with an enclosure, and a 800Watt amp. It will sound better, look better, and is a better value.

I love this sub I just can’t believe how incredible this sub sounds. This purchase is my second for another one of my customer. This sub is so inexpensive for sound it produces two thumbs up.
