About

O'Brien Car Audio was founded by Thomas and Marissa O'Brien in 2017. OCA is located in Rock Springs, Wyoming. A small brick and mortar store with an online presence. Thomas has been in the Car Audio scene for over 15 years, he is not only a business owner but the man behind the installs. 

After years of competing in Car Audio, they decided to open the install shop. Thomas competed in Super Street 5+ while Marissa had a Super Street 3-4 build for many years. They got engaged at World Finals in Sacramento, October 2013, along side some amazing friends and mentors. 

Over the last 7 years they have been able to quit their full time jobs, buy a building, and continue pursuing the dream of business owners. Marissa has an audio apparel brand as well! Bitches of Bass is ran here at O'Brien Car Audio.

 

Show casing some of their competitive builds over the years. 2009-2015 Thomas competed with the Chevy where he had 5+ designs in this truck. Marissa had the 1988 Honda Civic with a full DC Audio build until 2018. Don't these photos bring back some good memories?

In 2015 Thomas built the van. 8 DC Audio lvl 5 15's and 4 DC Audio 9ks. Marissa ended up selling the Honda in 2018 and building the Chevy. 6 years later they still have a van build and a Chevy build. Thomas's van has 8 Trinity Audio Solutions H15s and 64,000 watts with 8 Trinity 8ks! Marissa has 6 B2 Rampage 15s and 6 B2 4500.1 amplifiers.
