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.

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.

Very sleek and powerful

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!

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

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

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!

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.

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
