Hello, I'm having some issues with my system that I can't quite pinpoint. When I bought my subaru loyale it had an aftermarket deck and front speakers. Since I bought it I have put in a new deck, a sub, and just recently upgraded the speakers. I bought some 6x9 hertz that I put in the front, and moved the 5-1/4 infinitys to the rear. I am powering all four off of my kenwood head unit. Obviously a bit underpowered but taking it easy and will be upgrading the amplifier soon. Anyways, my problem is that the speakers are popping and crackling whenever I set the fade either to rear or front(not even all the way, they even pop if you set it a little bit. Any help would be great!!
