Update: The distortion returned a couple days later. I called
Crutchfield and they sent me a prepaid shipping label and will refund my full purchase price. They are completely out of stock of most JVC head units due to the chip shortage but I managed to find the same exact model listed on
Amazon through a highly rated third party seller. They had 8 in stock when I placed the order. It will be here Saturday, so I'll make the swap over the weekend. I have my fingers crossed that this will fix the distortion issue. I will update this thread next week.
