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 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....

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

No reason not to like it!

I used the NVX amp install kits and have been pleased with the quality of the materials. I needed some extra interconnect for trying out different configurations and this fills the bill. I have used these interconnects to carry both high and low level signals and have been very pleased with the flexibility and quality. You can spend more, but you should have a good reason to. If you need better cable, you really need better equipment!

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.

RCA's

I like the way these RCA cables look and feel! the only complaint I have about them is the end's... The male portion of the RCA is not solid it is a hollow tip that doesn't feel very solid HOWEVER, I would recommend these for the price.

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.

Works great.

No complaints at all! It's an RCA, not much to review!

Very Clean Sounding Amp/ DSP

I was replacing an old JBL MS-8 in my BMW. I originally gutted the entire audio system. So, all the infrastructure was already in place. It was a simple swap of connectors etc. Even if I didn’t have all the various connectors etc in place, it wouldn’t be too bad.

I have 2 additional amps in the car. I did not use the filters in the software (high pass & low pass) on any speakers that were already using filters (via the amp). The ability to parallel settings is a nice & time saving feature. My only complaint about it is that the USB connector cable needs to be about 2-3’ longer.

You do need to set the mixer and tell the DSP what channels you are using and what speakers are powered by each channel. This was not clear in the directions.

The software was easy to down load from the JBL website. It can be a little overwhelming to look at, at first. I’d suggest using YouTube / https://youtu.be/CNPjM3Xe7bI

The above was a helpful video.

GREAT wireing mounting kit

It does what it was designed to do . Made with top of the line material and keeps any engine sound that you would get with an inferior product is non existent !! The quality is as good if not better then Alpine , Fosgate , Kicker , ect..... The kit provides plenty wire to complete the job !! Not to mention the top notch service that Sonic provides . Fast shipping and professional assistance !! Will ONLY use Sonic for my future car audio needs .

Love this little amp ( for my needs)

Great for a factory upgrade. Installed in a 18 4Runner under the driver seat. I've got 9 (8 + 1 sub) speakers on 7 channels. I'm running it off the stock Toyota head unit. This amp about doubles the power and nearly doubles the volume. What sets it apart though is the value for the DSP. The channel delay function although subtle is noticeable improvement in sound stage. The software is easy to use. I had my installer route the amp's USB cable to my center console so I can plug in my laptop anytime and tweak. You could spend hours tuning. If you are replacing stock speakers randomly this will allow you to really overcome issues. I would think even adding this to a totally stock system would make a world of difference. We'll see if lasts !

Great Amp, Terrible Webstore

I love the amp, but so far I keep getting let down by Sonic Electronix. The first time I ordered it, I received and installed it, but it had numerous problems. The first one was that auto turn on would not work using the audio signal. The second is that it would not accept low level input. The third is that when using high level input, the amp would cut out under moderate load. I sent that one back, and received another, this one will not accept input from channels, 2, 4, and 6. I would love to give this amp 5 stars, but 2 duds in a row seem very unlikely unless there are a considerable amount of bad quality amps out there.

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.

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.

Great value

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

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.
