- Nick Apicella
He designed his own line of sound deadening materials that have been independently tested to be best in class. The tuning ability here is simply remarkable. There’s only a handful of elite tuners across the country and Nick is a master of the craft. Best of all though is his customer service. There’s not much he won’t do to satisfy, educate and assist his customers. For all these reasons and more, I’m proud to be a ResoNix customer and highly recommend them for all of your audio needs.”
Nick has taken dozens upon dozens of hours working with me on system design, tuning, troubleshooting and everything in between. I used several competing sound deadening products before discovering Resonix and it was a massive positive change once I outfitted my vehicle with the Resonix suite of products. The audible and measured results speak for themselves. It is clear Nick puts in hundreds of hours into honing his craft, products, and his business.
Nick (ResoNix) is a man of his word. He knows the automotive audio business. He knows his product, even better than most of his direct competition. For years, I've always known him to keep his word and he stands behind the Resonix product. I've had 7 or 8 interactions with him as a customer and I see no reason to not have more in the future.
Finding businesses that care about customer needs is rare today. ResoNix stands out. Nick spent an hour discussing the best sound dampening options for my needs, even continuing our call while walking up a ski slope after hours. The support and product quality at ResoNix are unmatched. Their detailed installation guides make anyone proficient in vehicle sound dampening. Highly recommend ResoNix for exceptional products and support.
My name is Rick from Maryland. I've purchased several sound deadening products from ResoNix Sound Solutions. I've loved using their CLD Squares, Rectangles, CCF sheets, Fiber Mat, and Butyl Rope. They are easy to cut and install. The result is a 2019 Chevrolet Silverado that's noiseless inside while driving. Passengers are amazed at the quiet. The stereo sound quality improvements are very obvious. I'm thoroughly pleased with all ResoNix products.
ResoNix has truly been a godsend in the ENTIRE process from purchase to even after the installation. Nicks service is next to none, worth every penny. I bought the medium soundproofing kit for my 2023 Honda civic, and I ended up having just enough to cover everything with some leftover fiber mat and CCF, it made a noticeable difference, specifically with how well the bass and subs sound. Everything was very easy to use and consumer friendly. Nick has helped me on any question I’ve had, better than any other, thanks again Nick!
