True Capacitance

Keep your lights bright and your system bumpin'! The NVX XCAP1F True 1.0 Farad Capacitor will deliver. It has been tested to be a true 1 farad capacitor, unlike nearly all of the competition which are really 0.2 farad to 0.8 farad. Being that it is a true 1 farad capacitor you know you're geting optimum performance. You will notice improvements in your bass response (SPL), increase the peak power of your amp and help stabilize the voltage of your system.

Don't be Fooled, Get a True 1.0 Farad Capcitor

The NVX XCAP1F capacitor owes it's true 1.0 farad rating to the fact that is has more electrical conductors as well as a greater amount of dielectric than it's competitors that claim a 1.0 farad rating. This true 1.0 rating allows the XCAP1F to easily handle any stereo system with up to 1200 watts of power output. This premium capacitor simplifies the installation process with a built-in distribution block which allows for direct connections between the capacitor and multiple amplifiers.

As with all NVX products, the XCAP1F true 1.0 Farad Capacitor continues the company's goals of engineering excellence, and amazing prices.

General Features:

  • NVX Digital 1.0 Farad Capacitor
  • True 1 farad capacitor for systems up to 1200 watts
  • Built-in distribution block
  • Bright blue LED voltage display
  • Improves bass response (SPL)
  • Increases the peak power of your amp
  • Helps reduce dimming lights
  • Screw terminals for easy connections of power/ground cable
  • Includes mounting hardware for a secure installation
  • Color: Black
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Capacitor Specifications

Capacitance (farads)
Capacitors are rated in farads, and at times microfarads or millionths of a farad. The more farads the capacitor is rated at, the more electrical charge (and wattage) the capacitor will hold. Capacitance is defined as the property of storing an electrical charge between two separate conductors.
1 farads
LCD Meter Display
Displays the current voltage and/or other specification on an LCD readout.
Yes
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
1/0 AWG
Maximum Output Gauge Size
This number refers to the maximum size of wire that will fit into the output connector(s) of the capacitor, battery terminal, or any other connector with an wire output.
1/0 AWG
Built-In Distribution Block
A built-in distribution block simply means that the item includes a distribution block. The built-in distribution block will split the single power input into a multiple power output.

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!

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 !!

Nice looking cap

November 7, 2013

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.

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.

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.

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.

Currently installed capacitor I do not like the way the wires have to attach, this one with the built in dist. block will clean up my install considerably.

Ravi M on Jan 28, 2015
does NVX XCAP1F has a remote wire in it ?
megamike on Apr 17, 2015
Best Answer: Dear Megamike,

I had the same question, so after i fully charged it I had a pretrial run hooked all my cables together without run a remote wire to the cap and indeed this cap other than having a Dblock it contains an integrated remote connection with the function of a resistor. I hope this helps AND REMEMBER TO CHARGE IT BEFORE YOU USE IT.

I have a sub installed in my car and it has been working great for a few weeks now with no problems. I got in my car today and started driving around (without any music on) and my sub starts making a humming noise. It seems to get louder the faster I am going in my car and goes in and out. What kind of problem am I dealing with and my friend recommended I get a capacitor, will this help?
Matthew M on Feb 8, 2015
Best Answer: A capacitor is not a ground loop isolator, and I'm afraid it won't help in this scenario. It sounds more like interference on the signal heading to the amp. Can you isolate this by either disconnecting the RCA cable to the amp and listening for the hum, or swapping the cable. I have seen and read about folks getting hum when running their cabling beside their power, but I found by using balanced connections, I never ran into this luckily. I'd return to the cable routing and see if maybe the power and signal path are too close together. Cheers and good luck!

on this capacitor can the amp and capacitor share the same ground? i see that this cap has a Built-in Distribution Block.
Devan G on Aug 4, 2014
Best Answer: Yes and it's works perfectly too. I have my 0 gauge going to a distro block, then my 4 gauge goes to my nvx cap, then to my mono block amp, then my 8 gauge goes to my 4 channel. Running everything off a xs power d1200 w/o big 3 upgrade and system hits hard.

Doesn't anybody know how I can utilize the built in distribution block( with two amps a mono and a 4 channel), given that this particular cap does not have a rem wire option? The only way I know is using to two external blocks.
cesar d on Mar 4, 2015
Best Answer: As far as I can see there is no need for this cap to have a rem wire. The cap will turn it self on as soon as it detects voltage draw

What is the max working voltage? From the description, it looks like this should work up to 20V, perfect for an 18V (max, not RMS, nominal, etc.) system. However, I suspect this might just be the voltmeter's range.
Thomas C on Jan 5, 2015
Best Answer: I have found the working range to be 11-14 volts, usually 12.x. You would need a high performance battery and alternator to get 20V and probably a better performing capacitor.
