I hardly leave reviews unless something blows me away, and this little sub did just that. I have a 2025 Mazda 3 hatchback with the trash stock 6 speaker system that had basically zero bass. I was truly looking for the Cerwin Vega shallow sub because I heard it's better. After waiting and waiting for it to be in stock, the company not answering my emails, I decided to bite the bullet and buy this Rockville one, even though most people said to stay away from Rockville for some reason. This is my first purchase from them. When I say I was BLOWN AWAY by the sound of this thing, it's truly a game changer from my stock speaker system. Now don't get me wrong, you're not gonna be rattling windows of buildings. You can barely even hear it outside the car. But you will feel the bass inside your car. My mirrors shake. The seats vibrate. Drums can be felt in your chest. It bumps for a little sub. I have the gain at about the 12 o'clock position, and the bass boost all the way down. It blends perfectly with my stock speakers which is exactly what I wanted. Installation was a breeze, but I think that's just because my car was easy to work with. This goes for all 2020+ Mazda's from what I can find. Ones that have the factory Bose system are a little different though. Check YouTube for some install videos. My only "complaint" really would be that the wiring kit that it comes with doesn't come with any extra crimp connectors. I messed up the power cable's crimp and I had to go run to the store and buy a new one. Would be nice if they just threw in some extra butt connectors and crimp connectors. However for the value I understand only giving the required amount. All the other spare tire subs out there you would have to buy your own wiring kit. The sound and value for your money are top notch here. I highly recommend buying it if you're on the fence about it. I can't speak to longevity yet since I've only had it for two weeks, but I did also buy the warranty from Amazon just in case it breaks. Well worth the investment in my opinion.

Works very well. Installation was very easy and it sounds good. Not too much bass but just enough. Wasn’t sure if it would fit in my spare tire but it did. Have a Subaru forester without a full size spare. It still fit perfectly. Only thing I had to do was find a new home for my jack and tools. After trimming the foam insert the tools were in it fit perfectly on top of my foam right under the floor. Can’t even tell I have a subwoofer installed.

Best Bang, or BOOM, for your buck. Kicks hard, has adjustments at your finger tips, and includes amp kit. Can't beat that. I first doubted, but wanted to hear it for myself, and now I'm a believer. Good job Rockview!

Great entry sub. Fit perfectly in my wife's 2021 Nissan rogue sport. The factory system didn't sound good. I installed kicker speakers. Helped some. The sub really helped it all around. Only have it about a quarter of the way up. Pretty powerful for what it is and for the price. Also, helped with putting heavy things in the back and not having it cave in the spare tire spot. Had Best Buy install it for about $150. The installer thought it was pretty cool it had the amp integrated in it and the construction of it. Only thing I dislike was the wing nut for the sub hold down. I found the thread pitch and ordered a M8-1.25 knurled thumb nut from Amazon for around $8 for a pack of 5 unfortunately. The wing nut was about 1/2 in long. The knurled thumb nut was about half of that. 1/2 tall. Had to cut about 1-3/4 in of the end of the rod for it the clamp the sub down. Did that before I took it to Best buy to test fit it to make sure it would work. Great all around product for the money. Got everything done for around $400. JBL has a similar system. But, starts around $550.

Good, solid kit that includes very nearly everything you could need to install it - including wiring, butt splices, and ring terminals. You'd only need a line out converter or splices terminals. The only reason it gets 4 stars instead of 5 is because installing as intended (inside of the my spare tire), it rattles horribly against the rim of the spare, and sits a little too high in the wheel, preventing the floor panel that covers it from sitting flush against the floor itself. Otherwise it's very easy to install, it's not nearly as expensive as similar options(JBL'S is $400-$500), and it sounds great. No distortion when tuned properly and very easy to relocate or remove outright as necessary, given that its an all-in-one unit that isn't meant to be hard-mounted.

I've been looking for something to add bass to my vehicle without sacrificing space. Many years ago I had 2 - 12s and this is nothing like that. However, it will shake your mirror if you want it to. I like that it's easy to adjust without having to constantly go back to the amp and mess with it like you would with a trunk full of speakers. This is also nice if you are out later and don't want to wake the neighbors. You can tell it's very well made and a lot of thought was put into the design. Install took me about 2 and a half hours. The worst is always running the power wire through the firewall. But after that it was a breeze. Highly recommend for anyone who wants that little extra you can't get from even aftermarket door speakers.

Got my item early and installed it in my Audi SQ5 install was so simple and quick due to battery location sound is great good bass and easy adjustment only had to run to home depot to get a 8” long 14mm bolt and big flat washer to hold unit in place using the vehicle treaded hole the bolt that came with unit was too small for my application but unit gives great bass for what it is how long it will last only time will tell

Installation was a breeze and this thing sounds fantastic. I have an IDQ 12” subwoofer in my truck being powered by a 1000 watt monoblock Kenwood amplifier and this thing gives it a run for its money for a fraction of the price.

Just amaizing. I bought this for my Suzuki ignis and the base is perfect in the car. Rockville rocks 😍

Great bass for the price! Just wanted something to round out the factory sound system and it does a great job and takes up no trunk space. The audio installer recommended a 100 hr break-in period, so I didn't turn up the gain over 40% during that period. Sounds good now and time will tell how long it lasts under these conditions(moderate gain, no bass boost and overall volume rarely exceeds 50% max).

Se escucha de lo más rico, mi camioneta no trae sonido firmado pero con este bajo mejoró enormemente la calidad del sonido. El bajo ya trae el kit necesario para la instalación, no es necesario comprar el kit de cables aparte lo cual, aparte del precio, es otro punto a favor sobre sus otros competidores. La instalación yo mismo la realicé, no es cosa de gran ciencia, lo instale en una Seltos GT Line 2023 sin ningún inconveniente. Tomé la señal de audio de la puerta trasera derecha y al tener el bajo entrada para alta no hubo necesidad de conectar el remoto, fue una instalación facilisima. Lo recomiendo ampliamente, obviamente no es de competencia, no esperen obtener 140 o mas decibeles en SPL por que no es para competir, pero el bajo que se escucha dentro de la cabina es exquisito, para los amantes del bajeo pero sin hacer demasiado escandalo, no se van a arrepentir del bajeo que obtienen.

I replaced the factory Bang & Olufsen subwoofer in my 2023 Audi RS6 with this subwoofer. Easy installation as power and ground and factory sub wiring is all right there in my spare tire well. The factory sub is weak (a 6 inch speaker in a big hollow plastic tub). The Rockville RockGhost V2 sub is a proper 11 inch speaker that gives out fantastic bass, fully adjustable sound and is a great value. I highly recommend it.

Perfect
