Nice Wiring Kit

The following review is for SDSK2, which is a part of the bundle you are viewing.

This is a nice quality kit at a fair price. It had everything that was needed to complete the task.

I had purchased another kit that I really wasn't happy with, and decided to purchase this one. I liked the attention to detail in the preparation of this kit. Recommended.

Works pretty good

The following review is for SDSK2, which is a part of the bundle you are viewing.

I bought this product for my trucks doors, and I noticed it's thicker than other sound dampening material I've used before that I paid a lot more for. This is a great product at a great price

Easy to use, good performance!

The following review is for SDSK2, which is a part of the bundle you are viewing.

We used this in conjunction with a component speaker upgrade to a 2003 VW Passat. This material is simple to use (if you can work scissors and peel off adhesive backing, you can handle this stuff!), and you can easily cut it to any size or shape to fit your particular vehicle. Installing this material was the easiest part of our whole car audio upgrade project!

EXCELLENT

The following review is for SDSK2, which is a part of the bundle you are viewing.

Very nice sound dampening material easy to install and gives a great added depth to the sound of yr system, deeper bass and mids and also minimizes the resonance of the factory locations

Nvx = quality at the best price.

The following review is for SDSK2, which is a part of the bundle you are viewing.

I'm so happy with all my NVX products. They are always the best in quality and price. No smell and if it's not a lot you can apply it without a roller. (I used my hands and the back of a screw driver to really smooth it out)
