“I had Waves and Wheels upgrade my existing boat stereo and marine lighting. I now have 24 speakers and color changing LEDs in my cockpit. It's one of the better-balanced boat stereos I've heard at Lake of the Ozarks. Their marine audio products and their installation team are top notch. Customer service goes beyond the initial installation as they always make themselves available at a moments notice, even on a holiday weekend.“

“Jonathan came and educated me on our new suite of Garman products. He also trouble shooted why our depth sounder was not working and found the problem. He knows his business.“

“Julian did a top notch job with my boat. Installed a full suite of Fusion gear (speakers, amps, 2nd battery, all wiring, LED controller) He sent pictures frequently throughout the process and was extremely professional and friendly. I could not be happier with the workmanship and will def be using Julian again for my future upgrades!“
