Switched 12V question....
I finished my Alpine install, with help from you guys, thanks. It went fine, or so I thought. I couldn't find a switched power source, so I just gave it constant power. Then after leaving the car for a week, I find the battery dead. Upon charging the battery, I hear the head unit lightly humming. Can I assume that it was related to attaching constant power where switched was required? (I hope I didn't ruin my radio!)
Thanks!
