"Whether you're a seasoned expert, or this is your first time on the meter, we got ya covered."

Our rules are simple, straight forward, and we make it extremely fun. You don't have to be the loudest, or the cleanest install. One of the loudest cars scares me, but not because of the dBs. It's because of the 11yr old cheeseburger I seen once. I know it's still in there too!
