Who We Are
From DIY to NASA
Who We Are
Hi, I’m Nick, founder of ResoNix Sound Solutions. If you’re after top-tier sound deadening and premium car audio gear, you’ve come to the right place. Whether you’re a DIYer or a major player in industries like NASA, we’ve got you covered. We’re here to bring your sound experience to the next level.
...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 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 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.

Nothing beats ResoNix for sound deadening.
I’ve tried just about every sound-deadening product on the market, but nothing even comes close to Resonix. The difference in quality, performance, and effectiveness is night and day. With other products, I always felt like I was compromising—but with Resonix, I finally got the results I was looking for. If you’re serious about car audio or just want to make your vehicle quite and you want a buy once and be done kind of experience then Resonix is the only way to go!

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.

The support is not only top notch, the product is as well.
Finding businesses that truly care about their customers and that make recommendations based on what the customer needs and not what they would like to sell is rarity in today’s environment. ResoNix is one of those businesses. When I first called, Nick took over an hour of his time to speak with me about the different options available and what the best direction would be for me to go. As a matter of fact, the call stretched in to after hours and he continued the conversation as he was walking up a ski slope. That is dedication. The support is not only top notch, but the product is as well.

Your questions answered
When will my order ship?
Most orders ship within 24 hours of the order being placed, excluding weekends. If you haven’t gotten an update since placing your order after 48 hours, the product you ordered may be on backorder. Product stock information is always available on each product page. Some people do tend to miss this when ordering though. If a product is on backorder at the time of your order, it will be shipped to you the moment we have it back in stock.
Do I get tracking information with my order?
Normally, yes! Our system automatically sends tracking information. If you do not receive tracking info, please let us know asap. Sometimes we need to update our system and we can always send you the tracking info manually.
The unfortunate truth is that sometimes we experience issues with our website and our shipping software communicating, so sometimes tracking will not be received. If you did not receive tracking and you would like it, just shoot us an email and I can send it over.
Do you offer returns or exchanges?
Yes, we do offer returns on purchases made within the past 60 days, but on ResoNix Sound Deadening Products only. If it is not a ResoNix sound deadening product, such as products from Helix, Accuton Automotive, Micro Precision, etc. we only offer store credit. The only thing we require for a return is that the product is not defiled in any way, and isn’t missing pieces. Meaning, if you order a box of 20 Mega CLD Squares, you must return the full box, or none of it will be returned. What we can do in some cases if something isn’t 100% is offer it for sale as b-stock to those in our ResoNix Customer Support Group on Facebook, but it will not be a traditional return. Just shoot us an email, fill out our contact form, or give us a call and we can help you out.
Returns have specific instructions, so please reach out for help with your return.
- You must reach out to us to inform us of the return. The best way to do this is by responding via email to your original order confirmation email.
- You must ship the product(s) back to.. ResoNix C/O Partnership, 50 Holt Drive, Building D3, Stony Point, NY, 10980
- You must also put “attn: Jenny, Order #XXXXX” (include your order number so we know which order it is to refund).
- Send tracking for the returns to [email protected]. Again, best to keep this emailed within the same chain as the order confirmation email.Â
- Once we receive and inspect the products and determine they are in fact complete and undamaged, the return will be issued. Feel free to follow up with us throughout the process or if anything comes up. Thank you!
