There's been no mods to the vehicle. It's the stock JBL stereo. As I was looking into why the Multi-infor display was on (only the clock and light stays on) the stereo unit began to go on and off on its own without the key even in the ignition. I removed the ACC Cut relay and the problem continue to persists. The only way to date that I can turn both units off is by pulling the Radio 2 fuse. With that fuse removed, my multi-info display unit as well as the radio goes on and off as normal. The only difference is that I have no sound out of the radio. Channels and various modes can be changed, just no sound. I've checked all the connections at the rear of the deck, as well as the multi-info display. All connections were intact and secure.
