W12K6D4 V2 12" Car Audio Subwoofer, 2400W Peak/600W RMS, Dual 4-Ohm, Deep Bass, Durable Build, Flexible Wiring, for Car Audio Enthusiasts

To be quite honest, I was skeptical installing anything but Alpine, I’ve been into car audio since 1998 and ALL I ever used was Alpine... Got married and and had Better things to spend my money and time. But the Audiophile never went away.... Took and old Type R 12 , made a box, wired up the Alpines and away I went. However I didn’t have the extra $$ to fork out for a newer Alpine sub, so I started watching a few YouTube channels and they were giving a Rockville review. A REAL honest Review... so for more than half the cost of alpine I decided to try this Rockville K6D4 V2. I’m running this off of a Alpine MrvM500 wired down to 2ohms, Wow, I couldn’t believe that a Sub in this price range would be built with such quality. I broke them in for a week and finally let it loose today.... My mirror fell off of my Windshield... I’m impressed...

I bought the sub it took a little while for it to get in but was worth the wait. I have it in a Qpower 12 box with a JL audio amp and this sub rattles my entire truck and it very clear. The sub hits all the notes perfectly. It pairs with my door speakers very well and everything sounds amazing I have it in a 96 ram and it sounds really good I highly recommend this sub for the great price.

Current setup is a 1st gen Durango with the rear seats folded down and the middle row removed. I've got a box up against the tailgate/hatch, and i just threw a pair of these in there. Certainly an improvement over the previous units, in pretty much every aspect. Im supplying power to them with a boss audio 1500w monobkock, and im certain that this is a limiting factor currently. Even still, my driving soundtrack tends to become the neighborhood Alarm clock. These speakers make the picture frames on your living room wall buzz and vibrate when im rollin through. Soda in my cup holders go flat in record timing. My mirrors are made absolutely useless when I play something like LTE, XLR, or Glacier Pack... and there's still more to be had once I improve my amp game. Also, they arrived sooner than expected. I did have my worries when only 1 box arrived on my porch - luckily it turned out to be a split shipment and speaker 2 arrived the following day

rockville subs are truly cheap and super fun and loud. get a good box and amp for them, used them for 2 years and all though those winters and they still sound just as good as when i got them, they arnt gonna blow out your windshield but man they are super fun and loud and they do sound really good with the music

Honestly probably one of the best “bang for your buck” subwoofers out there. These things can handle power and the build quality is outstanding. can start to stink a little when running at rms power for long periods of time with decaf music but holds up just fine with regular music. I have two and if i decide to upgrade i will be sticking with rockville.

I had to do some sanding on the box in order for the subwoofers to fit but they sound great. If you don't have the equipment or experience to do this, you'll have to have someone do it for you. I would give them 5 stars but it took me some extra time to do the sanding. So far so good!

Very happy with the Rockville K6 I bought. Wired at 2ohms, this thing really hits hard! Just installed a few days ago, but so far I'm very impressed.

Bought these in June and I can say they are worth every penny. Fast 2 day delivery and after having them about 5 months I think I've finally broken them in. These 12's can drop some pretty good lows. 2500 power acoustic amp with them has my whole car vibrating

Hot damn! 12 hrs running time so far and it sounds great. Worth the money at $137. Clean. The Rockville db15 might be too much for it, but loud as i want it, nothing is getting hot after hours of rock. Stereo feeding it 63Hz with no gain. Amp cranked. Paired to an alpine system with a db55. I finally have the sound i been looking for. Seems subtle even, but powerful and sharp. I will let yous know when i get deaf or dumb enough to blow it. Update, maxed everything including volume and my eyeballs were vibrating so hard that i couldnt see.

Very impressed. Didn’t fit the box I bought to fit under the seat but with a bit of hack carpentry and well placed sound foam it fit in. Using super cheap boss amp dialled way down and fills the cab with bass you can feel. Kept under my $500 budget for the whole deal. Battery terminal crimper included. Don’t just attach speaker wire on one side as I did. When I followed the diagram and instructions it sounded even better. Rounds out my factory ram with upgraded speakers perfectly. Solid and heavy

Good sound and boom
