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.

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.

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!

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.

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
