The products you offer are clearly top of the line. After learning from Kyle about JL Audio and their w7 line, I could no longer settle for anything less. I feel lucky to have stepped into the right place at the right time. I might have made a purchase I'd regret if I had stopped anywhere else.

I have used Auto Trim Design many times over the years. They are true professionals. Dave is the best audio guy in the area - a true craftsman.

I've worked with other shops before for car stereo. They left my car in shambles and did some shady "engineering" that ultimately led to the product malfunctioning. Kyle was a pleasure to work with, he helped my malfunctioning parts last until the new ones arrived and restored some things that the other shop had messed up. I'll definitely be back to work with this shop.
