This cup holder is designed to fit regular cans as well as larger beverages like Gatorade, Ice Teas, etc... The original cup holder could only hold soda cans. So I ended up making a deeper and wider tiered cup holder. It replaces the existing cup holder for the Pioneer 500 SxS, it may not fit other pioneers.
I am considering adding a twist lock design to securely lock the drinks. I will update this thing if I get around to it.
