Origin Story

Hello, my name is Nick Apicella. I am the owner/operator of ResoNix Sound
Solutions and Apicella Auto Sound.

Apicella Auto Sound was my primary business where I specialized in high-end car
audio installations but also handled automotive electronics, general custom automotive fabrication, PPF, and of course, automotive soundproofing. But, as of April 2023, I walked away to focus my efforts on ResoNix full time.
Part of executing a high-end car audio system is the sound treatment that goes into
the car, ensuring nothing rattles or resonates. To our clients, this is a big deal.
No one wants to spend five, sometimes six figures, on a high-end, sound quality
focused sound system just for the car to rattle and make funny noises while enjoying said sound system. These considerations mean that what products we use and how we use them is critical.

By the way, the name ResoNix comes from a play on the words and the idea of “nixing” resonance.

OUR TEAM
The Minds and Hands Behind ResoNix’s Innovation and Precision
Nick Apicella
Nick Apicella
ResoNix Founder & Owner
Hey everyone! Many of you may already know me. For those that don’t, my name is Nick and I am the founder and owner of ResoNix Sound Solutions. A little about me: I am an audiophile that gets most of my sonic perfection addiction fix in the car. Starting back in 2010, right before graduating high school, I became obsessed with car audio after hearing one of my best friends’ new sound system. This obsession very quickly evolved into the specific niche of high-end sound quality focused car audio. Anything that had to do with making a car audio sound system sound great, I wanted to know it inside and out, and be able to do it myself. Anything from installation and fabrication techniques, speaker location pros and cons, acoustic measurement software and techniques, DSP Tuning, OEM integration, and you guessed it.. sound treatment..

This obsession grew to an insane level where it consumed my life. I worked at a shop in Manhattan on and off over a couple of years during this time. Eventually, in 2017, I started my own company, Apicella Auto Sound, working out of my parents driveway doing sound quality based sound systems for those that were familiar with me from internet forums and groups.

Soon enough, I had my own shop and was becoming well known around the world for what I did, and was serving clients and building their cars after being shipped in from every corner of the US and everywhere in between.

Outside of car audio, I’m relatively simple. The only obsession that is more important to me than car audio is snowboarding, which I have been doing extensively since I was 6 years old back in the winter of 1998. As a kid I had dreams of being a professional snowboarder, but as my body started to not handle injuries well, I turned towards snowboarding videography and photography. In winters I worked for the local mountain as well as a short time Transworld Snowboard Magazine before their closure doing photo and video work. All of my photos are still shot on my trusty Sony A7Rii that I used for these jobs. The closure of Transworld Snowboard Magazine is actually what solidified my decision into going all in into the car audio industry and getting my own shop. Between snowboarding and car audio and operating ResoNix, you can most likely find me hanging out at home with my two sphynx cats, Gustavo and Peter, or occasionally blowing dust off the Xbox (now PC) playing Halo 3.
