"This shop is the best around! I've been coming here for years and sending alot of family and friends to see Jim and the professional staff he has. Always professional, knowledgeable and experienced! I feel lucky to have them within a 45 min drive for my latest upgrades and accessories."

"Awesome Audio Geeks: I brought my Porsche in to these folks seeking to improve its audio surround- which is challenging for a convertible. I am well-versed at auto mechanics, but only marginally proficient with car audio dynamics. Okay, in a few words, these guys rock. They are absolute audio geeks - they set me up with exactly what my car needed. Many thanks, guys."

"Been here before with no problems but had XKGlow fender lights installed in my brand new 2023 Jeep, couple months later my Jeep caught on fire while me and my dogs were driving in it. Was told it was the wiring from the installation of the fender lights. 22k in damages, no car for 4 1/2 months and now a fire on the record of my brand new Jeep which decreases the resale value. To say I’m livid is an understatement."

"Came in here with my 1990 Nissan 300ZX Twin Turbo looking for a sound system upgrade and they helped guide me through recommendations that could fit my taste and pricing on all options from inexpensive to highest quality. I appreciated them working with me and helping me find the system that was right for me. Great work!"

"these guys are great and stand by their installs. first, they were the only shop knowledgeable enough to install a remote starter on an Audi (RS5 B8.5, to be specific). No other shops around would touch it unless I wanted to leave a key in the glovebox. Remote starter worked great! Two years later it started giving me false alarms. Secondly, they stand by their install. I took it in, they diagnosed it for half a day while I waited, and they found it was a software update thing, not a wiring defect. half a day's labor at no costs. That's a company i will revisit"
