It was installed a couple months ago and last night was the first time it happened that's the only reason I suspected the update as the problem. I didn't install it myself so I'll have to check the ACC wire or atleast bring it to the installers for them to check it out. I'm pretty sure it powered off last night but I'm not 100% sure because it always turns off when I take out the key so I never really think about it.
And I don't have external amp or sub-woofer.
