Description

Description: The RG212CA v2 is in our opinion the best slim dual 12” powered car subwoofer on the market. This sub is a vented and more powerful version of our famous RWS12CA v2. The performance is better than systems that cost double or triple the! Our RWS12CA v2 is a 4.7 star product and we noticed one review mention that if we made a vented version with slightly more power It would be even better. After reading that review we decided to come out with 2 new versions. The RG212CA v2 is the top model and has the most powerful amplifier and (2) 12” subs built into the vinyl finished enclosure. Super slim The super slim design barely takes up any space in your trunk. Our engineers matched (2) 12” slim subwoofers with a vented enclosure and an amplifier tuned to perform optimally for this system. This model is only about 6” longer than the single 12”. So you still save a ton of space while getting double the bass! Huge sound! This model is like our RWS12CA v2 but significantly louder! It is vented and the amplifier produces more power. You also get (2) 12” subs with this model. This has enough power to shake your mirrors and be heard form 2 blocks away. There is also a built in limiter circuit that gets rid of unwanted distortion frequencies even at peak volume levels. RCA inputs and high-level inputs Use the RCA inputs if your receiver has RCA outputs available. Use the high-level inputs if you have no RCA outputs available like if you have a stock radio. Either way installation is quick and easy with this all in one solution. The Power, signal and remote turn-on terminals are angled which enables quick connecting or disconnecting. Remote bass knob included The remote bass knob can be mounted by your dash and allows you to raise or lower the sub volume from your dash. Adjustable low-pass crossover The adjustable crossover allows you to filter out the frequencies you do not want your subwoofer to play. For example, if you know your full range speakers are set to roll off at 80Hz you can set the crossover on the sub to filter out anything above 80Hz Features: Amp Features:

Honest review
Pardon the dust in the picture! I know some people say that's its not very powerful, I thought that too when I first hooked it up to my factory radio in my jeep run off of a LOC and then tried high input.. neither were very good for me. So I decided to replace my head unit and factory infinity speakers. Hooked it back up, plugged it into the aftermarket stereo.. and wow! now im sure you could find more power and better speakers somewhere else.. but for under 200 dollars? Its plenty enough for me.. does better than keep up with the bass in my JKU.. its an attention whore. Ive only had it installed properly for a week now. So hoping it will last a long time. This thing does have a very good sound quality, like I said.. for under 200 dollars im extremely happy.. that's a tenth of the price I paid for the rest of my system. It was very easy to install. Took me less than an hour to run the wires and Mount the unit with some homemade brackets because I do a lot of offroading so I wanted it secured. I thought it was going to be bigger, im sooooo happy the box it small and dont take up much room in the back. Very pleased with that. I decided to go with rockvilles 4 gauge wire kit, Altho I had to trip just a small amount of wire off for the positive and neg to load the wires in.the back of the box. Was no problem! Bottom line: so far im very pleased with the size, quality and BOOM. Super easy install in my Jeep (Granted ive had my jeep in a million pieces a million times so I know every wire and all the places it run through the firewall.) But all cars are pretty much the same. Im sure there are videos on YouTube to help you out. I was not paid or didnt get anything from this review. Just a simple and honest review. If it craps out at any time I WILL update this. One last thing: the single 12 box is only like 6 inches shorter than this double 12" sub box. For those of you who cant make up your mind on the extra space. 6 inches wasn't much difference for me.. ( that's what she said). Good luck and boom on jeepers ... show more

Buy local instead.
Don’t bother unless you live in New York. Mine was professionally installed and lasted 3 months before a speaker went bad, put subwoofer in protection mode and ruined my brand new radio. Radio had to be replaced. Has warranty but it’s useless due to shipping costs. You have to pay the shipping back to New York. They quoted me 156$ just to box it. UPS ground costs 550$. The subwoofer costs 239$. Like I said unless you live in New York, forget it. Never did sound quite right either. Save your money and buy something local or something with a warranty that covers shipping both ways. ... show more

Great low budget setup
If you want something that will hit so low you can't breathe or so hard it shakes your eyeballs, this isn't it. The sound quality is quite decent, though with it's lack of control options it's limited. It's very thin, great for small spaces. One complaint I have though is that the RCA inputs stick straight out, while the power inputs are at a slant. You can't actually safely butt the box up to anything, so plan on bolting it in place or replacing RCAs often. I will likely make a bracket to cover them. This is only a minor problem. Keep in mind that a real deal set of 12" subs will cost you $200+ for each single component. Don't set your expectations too high. This all in one setup looks great, and is relatively hassle free. It isn't amazing, but is well worth it's cost. ... show more

Hits just right
It gave me what i wanted. I hv an equinox and there is no sound in the back. Now there is sound . Hits nicely, sounds good . Just enough to enjoy. The built in amp is so convenient.

Cheap box
Actual subs are decent quality for the price but the box is my main issue, I’ve had to fix the face of the box due to the glue breaking and the amp in the back is starting to get blown out, all of these issues and they aren’t even above 1/4 gain. I’ve only had them for about 3 months

Plenty of bass for price
This product was a little bit of a headache at first because I bought the used version since it was $100 less and they ended up sending me one that only has one working subwoofer so i was disappointed but after talking with Keisha for a few days and after it was received by their returns department they were nice enough to send me a new one. Customer service was great, shipping was quick but the only thing I was disappointed with was being sent a broken item besides that the subwoofer itself fits nice in the back trunk of my 2017 Kia Forte and now I have lots of more space compared to having a huge one 15 inch subwoofer kicker. The built in amp is also nice, that saves me even more space. ... show more
