"I opened Speed of Sound in 1991.  We specialized in car audio, security systems and remote car starters.  In 1994, we started to service multiple car dealers on the NH seacoast.  I have built a reputation through my customers by doing top quality work at a fair price.  Customer service is the most important part of my business."
