My driver front speaker would occasionally kick out when the weather got hot, so I decided to replace the front and back speakers before that happened this year. I replaced them with some decent Infinity 6.5s. The backs are great, but now both front speakers with make a pop sound and then produce nothing when I turn on the car, like 90% of the time. They'll come on sometimes and sound amazing. But I'd like to have it on a regular basis. Any ideas what the problem may be??? I fear the lack of front speakers will cause me to descend into madness.
