With over 50 years combined experience in the custom car audio and electronics industry, Marty Barry and Diego Magana, have an established reputation for their meticulous attention to quality and precision work while using only the best brands in the industry.

So happy I was referred to Marty at Custom Mobile Electronics.  Total class act who really knows the business and how to do quality installation.  Treated me well and made my system affordable.  They even take the time to really show you your new system and how to use it.  Super happy with the service, installation, and end product!  It’s so refreshing to see sincere, authentic professionals who really care about their work and integrity.
