Customer Ratings & Reviews

Great Product/Excellent Value

Used these to do my Big 3 and ground my amp and capacitor. Make sure you have a crimping tool or large pliers and a strong grip, these little things are well made.

Decent 4GA Lugs

Worked well I do not have the tool needed to crush these so I used a vice and a wedge. Worked well nice cable ends. Heatshrink is a nice addition. I would buy these again.

Great hardware

I chose NVX for all my wiring needs; from the silver tinned OFC for power, ground, and speaker wires, to the RCAs. After my research, these were the wires and hardware to get; and the pricing here is great.

Great Quality

NVX Products are starting to get alot of attention and I can see why...
Excellent quality!

Good Value

Nicely packaged. Good quality. Comes with everything you need for a good, clean install.

nice

5/8/16. This things are big. Better have a good set of crimpers. I used a little ball pein hammer to smash them nicely on the wire. Also comes with heat shrink tubes to clean your connections up. Overall excellent product

Good product

Good quality terminals. The reason I'm removing a star is for the package not being glued correctly. By the time it got to me, it was completely empty. I found the terminals in the box, however, all but one heat shrink had worked it's way out of the box and was gone.

Great Quality

Nice solid terminal lugs. Build very well. And high quality

Great ring terminals

I'm glad I purchased these from here instead of a local audio shop. For some reason, they have them undersized. But these were perfect. Just what I needed to have a secure fit to my 4 gauge cable without having to cut some of the strands to make them fit

Great bang for your buck.

As a DIY installer, I found these to be super easy to install. With a proper crimping tool, these were very easy to install, and gripped my 4 gauge wire really nicely. Will definitely buy again!

Good quality

Simple, as long as you have a IBHDCRIMP, your good to go

Nvx cant be beat

I purchase alot of nvx products and im never dissapointed and these are great! Why buy copper wire if your just going to put a cheep ring terminal on? These are pure copper silver plated at a great price well worth the few extra cents lol

Big and heavy duty

Very big, thick and heavy, could use them for battery/ starter terminals for a diesel truck. Used for big three upgrade.

Just as high quality as anything that costs more money

These work perfectly and are just as high of quality as Rockford, Kicker, or any other premium brand. Definitely Recommended!
