...the owner has poured his expertise & love of the industry into everything he does & sells.

"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. 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 and ResoNix have been my #1 trusted resource for all things car audio.

"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."

Man of His Word

"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."

Unmatched Support and Quality

"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."

Noiseless Inside While Driving

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 made it easy and effective.

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!

ResoNix Sets the Bar Higher Than Anyone Else

If you're newer to high end car audio or just in general, and you've found yourself considering a purchase from ResoNix, you definitely don't need any second thoughts.

For some, the price can be intimidating at first, but it's worth its weight in gold. Every product I've used from the lineup so far has not only worked well, but made a dramatic improvement in what I thought possible from a car audio system.

One of the immediate factors that helps you separate ResoNix from what's available elsewhere, is ACTUAL product lab grade testing. You don't even have to click to the back pages of the website if your into that sort of thing. Links to the results are right there on the same page as the product itself.

Taking only a few minutes to navigate the website, it's clear that this company has a passion for getting the most out of your system. It does this while also transparently showing you how that's possible. Additionally, free information is provided covering proper sound treatment application methods, and even tips for performing you own system tuning with a DSP.

That information doesn't stop there either. After your first purchase, you'll have access to the ResoNix customer support page on Facebook. There, you are free to ask any other questions that you may still have regarding the products and how to get the most out of them for your individual vehicle.

There's also the ResoNix companion YouTube channel. Throughout the journey with my own system, I've found the biggest help here. There's literally a three-part video that's over 120 minutes of the company owner himself demonstrating how to sound treat a car door.
Show me another company that does that.

That brings us to the head of the company himself, Nick Apicella. Nick's been in the car audio scene for a long time. His main objective in starting ResoNix was to provide an option for sound treatment unparalleled to the competition. After a former best option left the industry, he made the decision to source materials for his own installation shop. Shortly after, his customer testimonials traveled around enough to where it made sense to increase production for public consumer use.

It's only growing from there. In just the couple of years I've been part of the customer base, new products have been readily added. Now expanding outside of just sound treatment, ResoNix is beginning to offer actual speakers, amplifiers, DSP's, and vehicle integration solutions. This isn't just your run of the mill Crutchfield catalogue. These are some of the most sought after lines of product.

I hope I've helped make clear that this is a no-brainer. ResoNix Sound Solutions will leave no regrets.

As for some personal notes, Nick has taken the time to give me direct support on system design when choosing the right amplifiers and speakers. I'm one of those customers that doesn't have all the money in the world, and Nick has never made me feel any less for that. In fact, he's notified me of when the next sale period will come around instead.

Car audio is a pretty big hobby of mine currently. I follow other installers with popular YouTube channels as well. Guess who most of them call for when they need sound treatment for their own cars?

From DIY rookie to full confidence with ResoNix Support

When building my own system, I want to make sure I do it right. I have always DIY on the performance and engine tuning aspects of a car. I dove in head first, I bumped into Nick Apicella on a car audio forum, where he spend a good deal of time helping me out. I mean he took time out of his day to help a complete stranger without knowing if this stranger would even make him a buck or not. The information I learned was very valuable, no bs, just cut to the chase. He let me know some of the dumb decisions I was making to and offered alternative suggestions and info. I ended up redoing my first system and used the ResoNix Sound Solutions sound deadening products, they worked great, and for the boot I had a community of helpers via FB and on forums that I met via Nick. Shipping was ridiculously fast!! I was expecting a week or two, got my shipments literally next day! I then tried the RCA cables, man what a life saver! Easy to run and size to exactness! Customer service is top notch! Probably the best! Thanks for taking the time to both test and make sure the products perform better than what's out there, and ensuring your products are used correctly by having very detailed how tos that are updated often! Offering sound equipment for lower budgets to the highest! Can't wait to finish my second build, so far the sound deadening was 200% better than some of the other products I used in build 1. Part of this was due to understanding how it works and how best to apply it. Thanks and keep it coming!
