Customer Ratings & Reviews

Excellent Product!

I did a lot of researching around when I was looking for a 4 channel amp wiring kit, and I started noticing NVX products popping up quite frequently. I couldn't be more happy with this kit and the quality of the NVX products. The "Flexibility" in the wiring is really something you have to feel and NVX does such a good job with packaging, presentation, and making you feel like this is a high quality product. The design of this product is like nothing I have seen in amplifier wiring and I have really bought into this brand after purchasing a few of their products.

good product

worked well in installing the amp. Give you ever think to install a 4 channel amp. little pricey but does a good job.

Great Value

Buy this cable for you amp to get the best sound out of your radio and speakers you will be happy the sound is clear and loud

Very good kit and great product install options

So this kit gave me everything I needed minus a ground wire. I mounted this in the midcabin section of my boat so I needed at least a 20ft piece of ground. Aside from that the kit was perfect for everything I needed. Really liked the additional speaker wire because I ran out by about 15 feet prior to completion. Would definitely recommend the kit.

great product

Its a good hook up kit runs my amp perfect not had any issues with any of the wireing great value for the price

Great but got shorted on wire....

I would recommend this... It comes in a great display and has clean sound.... Only problem I had was it says that it comes with 65ft of speaker cable and I only recieved about 30..... I had to go out and buy an extra 20 or so feet of a different brand to have enough to wire my 4 doors... Other than that, it's fine....

It does the job

Bought this as a bundle deal with my amp. Great wire. Had it installed for a $100 by a professional. And yes it was done professionally. Only thing it doesn't come with us a battery clip. A minor expense $10 at Max at Walmart.

Perfect

They give rich sound. There long, and if you get certain amps you can get this with a discount. I recommend this to anyone who had a 4 channel or 5 channel amp.

NVX > everything!!!

I can find no flaws with any of my NVX products! These RCA's are wonderful too! My 2008 Town & Country is the happiest vehicle ever! RCA's are strong, flexible and visually appealing... even though all of my wires are hidden! Sound quality is GREAT! NVX is the best!

Nothing Fancy but it works well no noise

works very well so far no noise easy to run

Amp install kit

Got this kit to install a replacement amp. It came with everything I needed. Only Tahiti didn’t like was the wire was not copper.

NVX XKIT

This kit had everything I need for my Hifonics 616.4 amplifier. The wiring looks great and is a much better alternative to competitors wiring. Works great, looks great, came with everything I needed to install. I am extremely satisfied!

Best amp kits

I have used Belva, Truconnect, and NVX amp kits. NVX is the best by far, there is a real difference and worth the extra dollars but still cheaper than many. value , quality, and all bits you might need included.

Great value

Love my alpine speakers , wonderful product at great price. Would buy all my musical products here

Twisted pair RCA cable

Really flexible and easy to run RCA cable. No issues with sound quality. RCA ends hold nicely without being too tight.

Great flexible cables

These cables are easy to run and very flexible. No signal issues. No noise, just pure signal. Very happy with them. Easier to run than 2 pairs of cables. Happy with the quality vs price ratio

NVX XIV45

I ordered these RCA's about a month ago and in true Sonic Electronix fashion they arrived within a few days. They replaced 2 pairs that had started shorting out on me. They look and work great very good quality. I will be buying more later on when I do a few more upgrades. Pro's look and work great very good quality very good price. Cons none. I would absolutely recommended to any needing a 4 channel RCA cable.

buy now before this brand becomes huge and price cause its well worth it.

Pure wire with twisted braid. Good connectors great rubber coating n has little flex to it.
Nvx should charge more for all there produces but don't cause they know there stuff is good n it will sell and be known as one of the best brands out there.

Nice RCA cable

Very nice cable! Looks great, feels thick but is also very flexible. Would definitely recommend to anyone who is thinking about upgrading their car’s audio system. RCA cables have an important task.

Top notch!$

Honestly NVX is a great up and coming company! There products work well along with performing flawlessly! These wires have superb sound quality and look amazing as well! Great great great buy! Love them and also got the 2 channels as well,good job NVX

Great wiring kit

The quality of the wire is top notch. The power cord comes with a protective cover for under the hood. It comes with all the connectors needed to be successful in your install. The customer service was great when I had a question.

NVX XKIT 84

This works great. It came free when I purchased my amp and it had everything I needed for install and more. There is a TON of speaker wire included so if you are doing a project that requires alot you should be good to go. The fancy coating on the power lead is a nice touch.

Great value

Works as described best bang for buck in wiring no noticeable noise

Not Sure this is 100% Copper

Its a nice set of cables. No problem with sound or power running a 4 channel amp at almost 400W RMS. But I am not convinced this is 100% OFC copper. I have other plain copper wires. They are much more dense and heavy for their mass. This feels lighter than copper. It is also more flexible and holds less of a bend--when you cut it it is extremely more brittle than plain copper. It looks like there is as much tinning as there is copper. The speaker wire and amp turn on are about one guage larger than advertised according to my stripper, which is nice. It was also nice to see the speaker wires are double insulated with two separate layers of insulation. I like the kit, it seems to work. But having used plain copper many many times, this stuff looks like there is less copper than whatever lighter metal it is coated with.

Top Notch Quality

Exactly as I would have expected with NVX...a top notch, high quality amp kit.

Sounds better if not the same than more expensive rca's that i have used..

I've used Stinger , Rockford Fosgate, Monster, KK, Scoshe, and plenty others... the NVX sounds just as good if not better. Not a hint of noise, easy to work and made just as well as the others.. and all for about 1/3rd less $$. No brainer.. Worth it!

Overall the product is worth the money and it looks nice if ran correctly!

By Jason on February 11, 2018 Verified purchase

NVX makes that best kits!

I love the ease of use. Power and ground already come with terminal ring attached and shrink wrapped. First two feet of power cable has nylon mesh for protection from head inside the engine bay. Plus you get a bag of extras just in case. This is my second NVX amp kit and I will go with them again in the future.

Unstoppable quality

Absolutely no reason to buy gamey name brand RCA wires. Low resistance, no noise, and a great jacket. Thanks for the hookup!
