Cannot say enough good things about them. They fixed a botched install from the now out of business Ultimate Electronics. Jon took a lot of time away from other work to sit down and really explain my options. They also stand by their work and helped me when I had a hardware failure nearly a year after the install. At no cost for the labor they swapped out the faulty component instead of making me wait for the manufacturer to repair it so I didn't have to spend any time without my audio and Bluetooth. If you go to most shops they will not take the time to explain the products (or the salespeople don't understand the products) but that's not true at Handcrafted Car Audio. The only problem is I want to spend more money there than I can afford!
