Customer Ratings & Reviews

Great buy

The kit would work great in a car but in a boat the kit needs to have alot more speaker wire and a longer ground wire

great product

these rca's are really good and are really long. i have a 90 bronco and i ran them over the door to avoid any signal mixing and i cant complain at all

Great product

This simplifies the installation of multi channel amps while using premium materials

great sound

Highly recommended these for the best signal for the best price

Great amp great value sounds good with 4-5-inch Rockford fosgate speakers+ 1200watt Rockford mono amp. And. 2-12"Rockford. Subs it rocks.

Can't go wrong with Rockford fosgate bought it for my sons car sounds great; and would recommend this product.

Works as advertised.

>I got these to run my mids/high amp. Also got the single version and ran it to my sub amp.

>It is nice having full control over your audio setup.

>I am very impressed with the solid build on and quality on these cables.

>Easy to work with.

>I would definitely buy again. A+

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

Good stuff

I got this kit for 50% off with my NVX amp. The power wires are very nice, the 6channel RCA cable is fantastic and the speaker wire is great quality too. The assortment of connectors they give you didn't really help. I ended up purchasing my own nicer ones.

Awesome Amp Kit

This kit was free with an amp purchase. I definitely like it, but I used 9 conductor speedwire for remote wire and 4 speakers. Worked out very well overall, great quality.

Very complete! High Quality

What a great kit. Far exceeded expectations. Nice touches like, mesh loom for the engine compartment on the 4GA power cable, heat shrinked where the you cut to install the fuse. Speaker wire is heavy gauge. The power and ground are come with the end connectors installed. My only complaint is there are no instructions so I had to reconfigure the fuse to add the rubber connectors. At least I assume thats where they go as it didnt have waterproof bushings.

Great kit

I was impressed with this kit. Their claim of a "true gauge" wire seems to be true because wires are thicker compared to other wires I have used claiming to be the same gauge. Overall the wires seem to be of great quality. Patch cables are good. They aren't super high end, but they do the job well. I'd recommend it to anyone looking for an amp kit.

Awesome kit!

Nice flexible, durable, strong wires! Everything you need! Makes for easy connections/install! Thanks again NVX and Sonic!!!

NVX XKIT46 (5- or 6-Channel Amp Kit)

This Amp wiring kit was perfect for my 5-Channel amp. Wire is good quality and so far I have had no issues. Would not hesitate to recommend.

Great Amp Kit

This is a great amp kit. The actual wire is much thicker than other 4 gauge amp kits. It's also a very affordable price. I'm happy with the kit.

I live by these and FREE with an infinity amp. You can't complain.

Great rca wires

These wires came as part of my metraconnect set and proivide excellent quality for my 4 channel amp. Love NvX

By JeVaughn on January 2, 2016 Verified purchase

great amp

absolutely the best-sounding amp I've ever had complimented my JL speakers and subs. The best thing about this amp is how small it is.. it takes up LESS space then 2 4 channel amps !!!!! built-in DSP speaks for itself!

By Randall on April 30, 2020 Verified purchase

Great Kit

I've used this kit before. It's great, quality and aesthetics are great.

10/10 would do again.

By Justin on March 17, 2017 Verified purchase

Great value

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

Unbelievable!

Great power and clean clear sound out of a very small amplifier. Easy install and great controls. Mounted where there is not much ventilation and it only gets warm.

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.

By Anonymous on May 12, 2019 Verified purchase

Love these!

They do the job nicely! Durable! No coming apart, breaking or kinking! Sound better than my old set!!

Very High Quality

Very High Quality wiring kit. I was impressed with all that came with the kit. The only suggestion I would make is to have the kit come with the fuse already mounted in-line at the 18" mark, between the two tape marks on the hot wire.

By Mike on March 26, 2018 Verified purchase

Always nvx

These nvx rca cables are well made and exactly what in was looking for at a good price.

By Anonymous on April 24, 2019 Verified purchase

great quality. so far so good.

very high quality 4 gauge wire. I used this kit as an integral part of and upgrade in my 2016 jeep jku...I could not be happier with the way my upgraded premium marine grade kicker speakers sound with my marine grade 5 channel amp. I'm only running 800 watts total, 400 to the kicker 10" sub..also a top of the line sub from /kicker. but the clarity of the highs and added non-distorted punch of bass is phenomenal! plus I your guys' Q&A videos are awesome! keep it coming and hopefully you will get more Jeep Wranglers!!

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.

Quality Kit

Seems to have had everything I needed but did come up short on speaker wire although the installation was in a large motorhome.

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 Value

Product exceeded all of my expectations. The size of it is great which makes for ans easy installation. The sound quality far exceeds any other 5 channel amp that I have installed.

Mades amp install easy and quick!

This kit had all the necessary components for my amp install.Components are durable and visually appealing. Install done about a year now and component still look as if they were just installed. Wire lengths were enough for my install (5 channel setup in a compact hatchback vehicle). Great kit!

NVX XKIT46 (5- or 6-Channel Amp Kit)

The wiring kit contained exactly what I needed and even a few spare parts/connectors. The power wire had an abrasion resistant sheathing over the section that is under the hood and the ground and power wires included precrimped ring connectors that work and look great. You can't beat the quality and convenience for the price.

Great quality

This is my second NVX wiring kit and just like the first, it is well made and true to spec.

By Brian on April 11, 2018 Verified purchase

WOW

The kit came as a package deal with a infinity amp, not paying much attention to the bonus I became curios when I recieved the shipping info package was like 100lbs. Not much hardware however the cables are stunning, clean super elastic I am sold 1st class Sonic

Great value

Kit has everything you need to do amp install. Quality of materials is surprising for the price.

Nice Install Kit

NVX install kits are some of the nicer ones I have used. This on in-particular works great with their 5 channel amp. I especially like the extra layer of protection for the cable running in the engine bay, give everything a nice touch once installed. NVX wire is exactly like they say and true to size. I keep some on hand for other projects (big 3 upgrades etc) and it has held up really well in everything I have used it in, including an Off-road truck where other brands have failed.

By Brandon on December 8, 2015 Verified purchase

One of the best wiring kit

Love the wiring kit. Comes with everything needed for a complete setup.

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

NVX XKIT46 (5- or 6-Channel Amp Kit)

This package contained everything and more than i needed to add an install an amp to my stereo system.

Absolute Best Quality

This NVX kit comes with everything and just because it comes with everything doesn't mean that quality has to be sacrificed. The quality of this kit is absolutely amazing and the fuse holder is so perfect that I ordered another one for my big 7 uograde. I got this for free with my amp purchase and I didn't even bother looking at another kit just in case because of what I read in the reviews. I'm halfway through installing my system now and I can tell you they give you more wire than you need. Will buy NVX products whenever I can.

Great Product

This came with everything needed to install my 5 channel amplifier. Plenty of speaker wire in the kit.

By Chris on May 1, 2020 Verified purchase

Love these kits

I ave used a few of these 4ga and 8ga kits. Speaker wire is flexible and comes with plenty of length love that the power wire is pre loomed and is nice and flexible. The connectors I usually don't use because I like to use ferrules but they seem to be good quality. For the price, you can't beat the quality!

By Ben on March 24, 2020 Verified purchase

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!

Great Kit for the Price

You will not go wrong with this kit! It comes with everything i needed. I especially like the amp power wire that is braided for the engine compartment!

By Mike on May 2, 2018 Verified purchase

NVX and Sonic get it done!

I was skeptical when I ordered my amp and saw that this kit was included. I assumed that it was going to be a bunch of cheap cables and wires, but boy was I wrong. The power cables are extremely nice quality, they rival some of the best name brand cables I've used. The speaker wire is also VERY nice and the fuse block is legit, heavy duty equipment. The RCA's are a little strange looking and are probably the only cheap looking/feeling part of the whole kit, but even they are more than usable. I wouldn't hesitate to buy another one of these kits for my next install.

By Bill on March 30, 2018 Verified purchase

Just get it

Excellent purchase at the right time. Huge discount during the Christmas sales. Thanks Sonic! Fit my car and very happy with the quality.

Unstoppable quality

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

By Thomas on May 28, 2020 Verified purchase

Does the job

Works fine. Colors for the plugs could be better. White black blue and gray

Quality wire

Great wiring kit and speaker wire. Worth the price for quality.

Great Quality Amp Kit

Well made and is very sturdy. Easy install, True OFC. It's worth the investment on your amp and the charging system.

Switching to Crutchfield

Like these at first, then they turn out to be loose RCA cables sonic got rid of many products back in the old days. know every day less products or more expensive switching to other stores

Great kit

Amp kit is the way to go. All the little zip ties and crimp ends really make a solid kit for installation for sure.

By Chris on August 10, 2022 Verified purchase

Complete kit

Amazing high-quality kit. This is a must for larger multi-channel amps.

By Figment on July 18, 2022 Verified purchase

Great amp but……

The only thing keeping this from 5 stars is the cheap plastic connector for the digital input. Mine broke day 1 and now I get intermittent sound. You would think something so critical would be reinforced or build into the housing better especially on a $1,700+ amp. My pac pro even has something more robust and reliable.
