alright, so i have a pioneer in dash double din dvd head unit. I also have have aftermarket kicker speakers up front and the stock 6x9's in back. sometimes when i start my car up theres no sound though. the head unit has power, but nothing is going to the speakers. i'll turn off the head unit, wait like 10 minutes and then turn it back on and all of a sudden there's sound. It doesn't always happen though, but it happens more often when its cold outside. I'm thinking that it could be my battery isn't strong enough, what do you guys think? i didn't install the head unit, best buy did. But i also have footwell LED's, so i'm wondering if i just have to much draw on my battery. IDK though, i'm baffled by this. anybody have any ideas?
