NVX cap
I have a 2200 watt hifonics amp pushing my subs (hard) and a hifonics 1000 watt four channel running my components. Never once have I had headlight dim or anything. If youre looking to save some money by not buying another batter/alt this is for sure the way to go.

found this helpful.Awesome Cap!
Had to give it a try and it did its job as described. This cap made a big improvement in my system, bass response was better and much less power loss to my aux equipment. Never been a believer in capacitors but this one changed my mind, very happy with my purchase! You will not be disappointed.

The Nvx XCAP10H is a fantastic product, my other capacitor died and I needed another. So I upgraded to this one couldn't be happier

Great for a dual amp setup. I'm running two 5000 watt re-audio amps to two re-audio 15xxx's. The cap alone could handle short runs, but after added a second battery, it never drops below 12 volts. The cap looks great and only displays the voltage when it changes. Big punch in a small package!

found this helpful.one to buy!
This thing rocks,very slim,very easy to install. Would recommend this cap if your looking for something that can be mounted almost any wear. You can use 4 or 8 gauge, it even drops down to 0 gauge. Very cool product

found this helpful.Not sure
I haven't had a chance to put this to the test. Unit is easy to install, however the manual could be a bit more specific. Had to watch you tube videos to figure out how to properly charge and discharge it.

found this helpful.One of the best!
I have installed somewhere around 30 capacitors in the automotive world and each one has some kind of drawback, sometimes even making me uninstall the cap in favor of another one. This cap, however, is one of the best I have ever used. I am having a difficult time finding anything negative to say about this cap. Somehow, NVX managed to fit 10 farads into one small package. Upon further reverse-engineering of this unit, I discovered one small oil cap, and numerous electrolytic caps. This hybrid approach really delays the need for additional batteries in the trunk because it has mechanisms for quick and slow power delivery in one little box. This kind of technology will never reduce your need for a higher-powered alternator; if your system draws more than your current alternator can sustain you need a bigger alternator. This cap reduces voltage fluctuation in the system which can be noticed with "dimming lights". Voltage fluctuation in my system before the cap was about 2.5v with a properly sized alternator. Now my voltage fluctuation is at a cool .4v!

found this helpful.Well worth the money so far
I give it a 4 simply because the instructions are either read in a understanding but not accurately helpful like what size fuse you are supposed to use and didnt mention if your supposed to fuse from the amp to the cap and cap to the battery it says to fuse to charge the battery and then that how to charge is confusing. You should ( sonic) should put a instructional video that is about this cap and only this cap. I hope this helps whenever wants one just make sure you know what your doing or you can hurt yourself. I use a 1500bd and a t2 s1 and 2 batteries and this cap big 3 and ho 180amp alternator and this cap was worth buying it helps my car even when I'm not using my stereo I feel and notice the difference from turning my headlights on up and down the windows no idle drop at all. 97 honda prelude

found this helpful.works like a charm
I was very skeptical about purchasing a cap because of all the thing i heard about using it. They say a cap is a band aid to your electrical system and don't see any benefit from using it. Due to the limited space i had in my storage area under the back of my Durango, didn't have enough space for a battery. Reading all of the other reviews of this product lead to to purchase this cap. I follow all of the direction it took about an hour to change it up. This cap is the truth I'm running a 2500 watt Brutus elite amp down to a 1 ohm load and at full power my voltage don't drop below 13.8. I did do the big three but I'm using the factory battery. It also made the bass notes hit harder and cleaner due to the cap feeding it all the current it needs. If you were skeptic like I was, this is no doubt the real deal. You wont be disappointed

found this helpful.Best bang for the buck
Bought this last year to drive 3 amp system and maintains voltage no matter how I play it. Having the built in distribution block is very helpful. The only thing I did not like was the charging board but I used an old fashion test light and it charged in no time at all. I believe in this product so much buying this cap again for my new ride. Looks very similar to the Rockford version but at half the price.

found this helpful.Solved my audio drop out issues
I know that some say that a capacitor is like a bandaid, but this is one great expensive bandaid.
Over the past few months, I've had audio drop outs when I turned up my amp. Protected light would come on, especially on punchy basses.
I checked everything. Wire connections and all. I have 1/0 awg connected to a 150amp fuse with a Kicker 1800watt amp. 2 Power accoustic 1500 watt rms (aware of the wattage difference in the amp), 150 amp alternator with a newly installed Optima yellow top battery.
Everything looked okay. Maybe I need an upgraded alternator, which doesn't make sense because I had this same setup in my Honda Civic with no issues.
Well, installing this, solved the issue. It's even better than the Honda Civic loudness I believe.
Now, I'm upgrading the amp and speakers for even more power. Alternator upgrade as well.

found this helpful.#1 Bass Cap
Without a doubt this is the best bass cap you can buy! Rockford foagate makes the very same cap there is nothing different about it, besides the price! I have 2 12" DC AUDIO LEVEL 3 subs being ran by an Incriminator Audio 20.1 amp on a factory alternator inside a 2007 Yukon Denali and I have "0" light dimming issues with this installed..I mean none! It takes a while to charge up at first using the included resistor, but once it's charged it works perfect! Been thinking about getting another one just to keep on hand in case they discontinue it. I really don't feel there is a better one out there right now, and I've been buying caps since 2000 and installing car audio in my car since the 90's. Buy it!...

found this helpful.Really nice
I have powered this with 0g and an easy fitment and have 2 amps running off from it. I say it helps the stability of voltage along with the other upgrades to my electrical system. It has been a welcome addition to my system.

great product, used on both of my cars and highly recommend, not just a capacitor but also a distribution block so if you have more than 1 amp of need a capacitor this one is strong and kill 2 birds with one stone,

found this helpful.Very Nice !
This is the best 10 farad capacitor for the money on the market right now. I had a whining noise before I installed this and after the noise is gone. I grounded this the the frame and ran the other wires back to the 2 amps and the whining sound is gone and I have no interruptions in bass at all it supplies a constant voltage to my subs .

found this helpful.Great Capacitor
Works like a champ. Pushing over 1500 watts RMS and voltage is always above 14 volts with factory alternator.

Its identical to rockford fosgate but cheaper in price but is equal in comparison.

Got it on a DD m4a and it holds it pretty solid.

found this helpful.Powerful upgrade
Nice install options however nowhere in the instructions mentions the doors that open on the sides. Nice display and seams to have added clarity and bass. I have a system volt meter on the dash gained son stability. However I’m running 3. Interestingly it’s exactly identical to the Fosgate.

found this helpful.Excellent quality
Purchased this cap at act as a buffer on my electrical system. This is in no means a bandaid for a weak electric system. I love that it has a built in voltage meter and the distribution blocks worked out great for my amp setup. I have this on a Hifonics Colossus Pro 5K and even with this cap it seriously pull down my voltage at full tilt, but I'm having a custom built 270amp alternator for my car right now. I will be perfect for keeping a steady voltage flow to my amp and prevent spikes. I would definitely buy again. Exactly the same as the more expensive Rockford hybrid cap at half the price.

it work like crazy ,i have just instal today ( 4-june-16 ) .. i have an amp. rockford fosgate T-2000 @ 2386w. rms @ 1ohm, no more diming light anymore and my subwoofer are in a box of 4 ( 400 w rms X 4 = 1600 w rms total ) ,, this capacitor exceed what i was expected for....it took 3 days for shiping im from Qc. Can., service is amazing also...

i just receive the NVX Capacitor 10 farad competition , brand new , all i heard was good comment about this cap, i can now confirm this is a very good product for the price , similar like Rockford Fosgate but cheaper..thx Sonic.

found this helpful.Awesome
I had ordered two of these NVX capacitors, one was defective out of the box but they replaced it fatherly quickly, saved my truck from stalling out with my system. I currently run one 12” EVL Skar subwoofer with the recommended 1500 watt amplifier and it would draw enough voltage to stall out. My lights still dim slightly at higher volume but for the price, size, and it’s effects I definitely recommend this product. My only complaints would be the poor labeling one the blocks themselves and the flimsy door covering said blocks.

I have a 270 amp alternator and still couldn’t keep up with my system. I through this in parallel with my sub amp and door speakers amp and now my volt gauge doesn’t move. Very happy considering my system peaks 320 amps and my alternator output is 210 at idle.

pro's-nice, love the read out and the ease of install.
Con's- the only thing I would like to see is better charging instructions with the charging light they have. it has four wires off it i now pos and neg. and there operation. if I had not ever charged a cap prior to this on it would be difficult and confusing.
