NVX XCAP1F - Customer Ratings & Reviews

Big volts

My uncle big bubba got me this cap and I have no volt drop. I have some serious power I have a 25 watt system and this cap really helps a lot.

good value

For a 1 farad capacitor it's a good product. The distribution cap makes ease of install versus a regular capacitor without one. The blue voltage display matches my setup currently. It does help with the power loss, but isn't enough for my 600w rms setup. For the money, features, and ease of install it's worth the money.

Solved my problems quickly.

Went from a junky Boss capacitor rated at 3 farad that broke to this one. Thank God. Seriously helps the dimming lights, quality made and looks sharp. The Boss one was all plastic and ridiculously looking and this fits nice in my car.

Great Product Great Results

I was impressed by the quality of this product. It supplies plenty enough power to my sub amp to offset my dimming light problem. Also fixed a spark plug energy shortage!

Nice looking cap

I have owned this cap for a few months now. It performs well. The best part is the charge/discharge device.
The volt display is not ideal for my purposes, but that is a small con.

Great cap

This is a great product. Have owned for about a month now and it just keeps pumping power to my amp. Everything stays stable and there is no dimming of my lights an its pushing a 1000 watt Hifonics hfi mono block. I would definitely buy again.

Exelent value

I purchased this NVX XCAP1F when I bought the rest of my audio system . I wasn't sure I would need one but with having a little Fiat 500 with a little battery and I am sure a bare minimum output alternator I put one in just in case . I am running a Boss CXX2705 amp that puts out 2700 watts peak and 1200 watts RMS so I put one in from the get go .I don't know if my lights would dim or not but with this baby there is absolutely NO dimming or power loss what so ever . This is a TRUE SPEC 1 Fared cap and made of the highest quality material .. I would put this up against any big name audio equipment out there , in my opinion it is built better then Alpine , Rockford Fosgate , kicker , ect.... , and is hands down the best value out there . Buy one , you won't regret it !! I have not cranked it up all the way yet because I am still breaking in my sub but at 65% of max volume it works without breaking a sweat '! NVX products are fairly new but are built perform !! ..Way to go Sonic for your superior product and service !!

Good quality

I bought this cap to go along with my nvx amp and I also bought the amp kit. I really like the quality of the amp kit and and the price was fair on the amp wiring kit and the seemed to have a fair price as well but after I ordered the cap I found it on nvx web site for 59.99 and contacted sonic electronic by email and wa told they would not price match. That kinda sucks that that I had to spend 40.00 more for the same cap and it not like the price match was some off the wall website it was the manufacturer of the cap nvx I guess that teaches you do better comparison shopping but over the cap and the wiring kit were pretty good quality

Good product

Work as it should I haven't experienced any dimming win my lights it's a true 1farad cap. It has some weight to it so you know it's not chaplain made.

Nice capacitor.

I installed this capacitor with 4 AWG wire and an NVX BDA7501 amplifier (4 ohm load, 480 W RMS). The voltage meter readout uses an internal comparator to sense a voltage change, which then illuminates the meter; It is not controlled by the remote lead, and therefore cannot be controlled by the user. This may be important for those with a hatchback that don't want a bright display randomly turning on and off in the back of their vehicle. Works great in my trunk though! No complaints really, just a clarification of its operation.
Included charge circuit worked well, and it installed without any problems.

Bastante bueno

Es de Buena calidad ,ademas es super facil de instalar

NVX XCAP1F

I cant say anything neg. or pos, about this product .install went great and everything is working well. I am not running a crazy amount of power just one lanzar opti hc 3502 and the main reason for getting a cap was just to support the overall electrical system. jeep/dodge are known for bad electrical issues. that being said we will see how long it last 1 month in now and no problems.

great cap

5/8/16. I bought this cap to help with my light dimming problem. I have a hifonics hfi 1000.1d. I had it wired at 2 ohms on a 12 cerwin Vega vmax. At 2 ohms my light stopped dimming. I then bought a 15 nvx to wire at 1 ohm on same amp. Let me tell you it hits hard. It helped reduce voltage drop, it helped stabilize my cars electrical system. Which reduces strain on your vehicle. But I will say at 1 ohm, when the bass is really hitting hard, my lights will dim slightly. Overall I'm satisfied with this product.

Son loves it

Placed it in his mustang to help combat the dimming headlights. Works for that, he thinks it looks cool. Good deal.

Great buy!

I got this about a month ago and it is great easy install and stopped my lights from dimming

Great Cap!

I purchased the XCAP1F, by NVX, initially because my headlights were dimming when the bass hit. I am happy to say that the xcap did the trick. I would definitely recommend this product to anyone else having similar problems with dimming lights.

Good Purchase, no dimming lights!!

I was deciding between this NVX 1 farad and a Stinger 1 farad. I decided to go with this one because it was not only a better value but NVX brand like the amp(NVX JAD 900.5) I ordered. All of the NVX products have good reviews on SonicElectronix so I trusted them and decided to order. I am very happy with my purchase. This cap performs on the same level as Stinger Capacitors that I have owned in the past. I measured voltage at both outputs on my distribution block and voltage meter reads 14+ volts constantly. I have the NVX JAD 900.5 and a Rockford Fosgate P500x1BD connected to this cap. No dimming lights and system sounds very clean. I would definitely purchase this again if ever in need of a good 1 farad Cap. Thanks Sonicelectronix!!

Awesome Product! WORTH IT!

My interior lights would dim whenever I would turn the steering wheel and felt like my car was going to turn off. This would only happen whenever I had the music/bass turnt up loud. I have two 12" JL Audio w3 with a hifonics amp 900wRMS @2ohms. I bought the NVX XCAP1F and never had a issue again. It even made my subs hit harder. I Definitely recommend this product. Set up was easy, the distributor block on top makes a difference. One thing I noticed is that when amp isn't drawing a lot of power, the blue LED voltage light will turn off. But as soon as you start to bass out, it'll turn on.

NVX XCAP1F TRU 1Farad digital capacitor!

Thank u sonicelectronicsThis capacitor is very good keeps my stuff at 14.2 it might dip a little bit not much and it helped out with other stuff in my car it keeps up with with my subs and amp it helps out way better than the ones I had in the past i’m running 2 Rockford Fosgate P3‘s with 1000 W stinger amp and a pioneer CD player and a scar equalizer and the Bose amp that’s in my car dang does it scream and bumps what do the kids call it it SLAPS!!! I like all music heavy metal, rap a tiny bit country but it keeps my car banging some times my ears are ringing after bumping so hard I like to fill my music not just here it
The only con is where I live if you want something nice you have to order it and shipping is not cheep
Up date after I charged my car battery to full man dose thiss thing help OMG!!!!! my 12 never hit so hard it’s making the needle on my RPM gauge bounce like crazy I might orde a nother one or just get the 10

Caps are they worth it

I have to say there alot of cap on the market. And there all different brands. Are they worth it yes and no. If your borderline on your setup I definitely highly recommend having one and make sure there actually install right. If your way over what your alternator can handle then no it won't help. Connections on this is absolutely perfect there charge and discharge piece makes life easier than back olden days. It's design is perfect for what it's use is. My setup was small I figure what heck I give it a try haven't had headlight dimming problem or abnormal voltage drop.
