Synergy Audio

Hello and welcome to Synergy Audio. We are a custom car audio shop that is located in the heart of the Midwest. This is no nine to five job for us. We love it! And we love to help anyone and everyone else as well.

We have selected our products based on their unbeatable performance in the DB Drag lanes. Only when a product has proven itself will we consider carrying it, so check back often to see our new line up.

Make sure to check out our project vehicles and customer rides. Take a look around and feel free to give us feedback on our Forum.

Synergy Audio is known for producing some of the loudest cars in South Dakota! Our passion is the audio, music is life, and the intensity of 150db bass is what moves us to help you!
