Yes it is bad. I'm not exactly too sure why but my best guess would be that electrical components have certain power ratings meaning they could only handle so much power. Like a balloon can only handle so much air or water before it bursts. Probably a bad example haha but I think it might be the same principle. Like I said, i'm not exactly sure what the technical reason is and i'm not gonna pretend like I do. I'll be honest, i'm a noob when it comes to the higher complicated things but I think I have a good grip on the smaller stuff. The real geniuses on here that I have seen are billboost and scottydoggs. Those guys are pretty comprehensive.
