Excellent Product!

The following review is for XKIT84, which is a part of the bundle you are viewing.

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.

Very good kit and great product install options

The following review is for XKIT84, which is a part of the bundle you are viewing.

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....

The following review is for XKIT84, which is a part of the bundle you are viewing.

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

The following review is for XKIT84, which is a part of the bundle you are viewing.

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.

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

The following review is for XKIT84, which is a part of the bundle you are viewing.

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.
