About us

Speed of Sound Audio Experts

We’ve been doing this work for more than 30 years. We install car audio, remote starters, car keys, security systems, headlight upgrades, marine and motorcycle audio, and aftermarket accessories, and we know the vehicles and the electronics that go into them.

That experience is what our reputation is built on: careful installs, honest advice, and work we stand behind. Tell us what you drive and what you want, and we’ll help you get it right.
