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.

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 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.

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.

Good Amp Kit that powered my ct sounds 4 channel amp

Rockford Fosgate

My item arrived packaged well, is much smaller than I imagined and will be great for installing in my boat. I have used the T series amplifiers in the past in cars and have no doubt this amp will be perfect for my 4 boat speakers. The killer deal I got helps too! Took advantage of the additional warranty as well.

Update:
Installed this amplifier with a Kicker install kit and Kicker marine speaker wire, 4x 6.5" M1 marine speakers and the Memphis SMC3 head unit.
Seriously the best audio system I've ever heard on a boat, gets super loud and is super clear with phenomenal bass for 6.5" speakers. Sounds better than my buddies boats with wetsounds and JL setups and I only spent about $1,000 for the entire system. Setup with the built in clipping indicators made it easy to achieve full safe volume. Set my HPF to 50hz.

Exceptional kit.

I used this to install a 5 channel NVX amp under the seat of my 2014 Honda Ridgeline. This kit is very high quality. The wiring and RCA cables are extremely flexible which makes them easy to work with. It has everything needed for the the install and I could ask for more.

Fosgate TM400X4ad – Small Amp, Big Attitude!

Running the Rockford Fosgate TM400X4ad in my 2013 Harley-Davidson Electra Glide Limited with 10 speakers, and let me tell ya this thing flat-out bangs. It’s small enough to tuck away clean, but the power it pushes is unreal. Crystal-clear highs, deep bass, and it keeps every one of those speakers screaming even at 80 down the highway. I’ve had people turn their heads at stoplights wondering where all that sound’s coming from — then I point to this little beast and they just shake their heads.

This amp runs cool, never clips, and delivers pure, clean power every ride. Rockford Fosgate really built a monster in a mini package with the TM400X4ad. Trust me you can hear me long before you see me roll up.
