Joel "Grommit" Sadenwasser is no stranger to hard work. He started his first business when he was a wee tyke at sixteen years old and began detailing rides for some extra coin.

Hanging around some of the San Diego minitruck OGs he began to take bodywork classes and soon found himself in the shop knocking down some bondo. Eventually Joel realized he wanted more and moved up to the big leagues. His name might sound familiar because after spending a few years perfecting his Tacoma he not only scored a cover spot, but he also took home the coveted Truck of the Year award. However, like many, he ran into some bad luck dealing with weasel painters, stolen insurance money, and the like, so Joel finally decided to take matters into his own hands and start his very own shop. No more listening to excuses, broken promises, and snakes. He vowed to deliver on his word and not let other people get taken advantage of and would deliver quality work, on time, for an affordable price.

Joel worked hard to round up a reliable crew and opened up doors as Extreme Audio & Kustoms. Every good shop begins with the right people, and Joel had a buddy that's been with him since the beginning. Adam "Handmade" Radovich is truly a marvel when it comes to custom interior design. His vision and creativity mixed with his know-how of making things happen make him the perfect righthand man. Adam has been in the minitruckin' scene for over 15 years and brings with him knowledge, experience, and most importantly, reliability. With the rest of the team assembled, including paint/body and metal fab, Extreme Audio & Kustoms is truly a one-stop shop, so there's no more bouncing from shop to shop and missing deadlines. With builds that fit any budget from mild to wild, Joel is dedicated to giving the same care and creativity to his customers' rides as he would his own. You couldn't find a better group of guys, and as you can tell by this month's cover truck that was built by Extreme Audio & Kustoms, their work speaks for itself.
