about us


At Precision Sound we've been providing reliable service for everything related to sound and audio since 1990!

With such a long history in this field, we've learned a few things along the way. The first is that our customers are our priority, as we want to exceed their expectations with everything we do. The next is that our employees are what make us memorable. It's for this reason that we hire only the most friendly and knowledgeable experts who can offer our customers genuine and reliable service. With these core beliefs, we've become a local staple for everything related to vehicle sound and customization.

We enjoy helping the community and are big supporters of those who serve us, such as the military and law enforcement. Our company has even been lucky enough to help with community-based project builds. When you become a customer of ours, you will become part of our family and find that you'll always receive the service you deserve no matter what your needs.

What can we help you with? You name it and we can do it! Our talented staff can work on anything, from buses and RVs to boats and cars. We also sell and install car audio, tail lights, car alarms, wheels, tires, lighting, and custom installations. We can make your dreams for a custom car or truck come to life.
