The last few days when I put my truck in drive the radio just cuts out. Everything is aftermarket which is why it's weird. It's a kenwood radio with 2 infinty's in the doors and 2 10" jl's behind the seats. I've checked all the connections and they're fine. Start my truck up and it all comes on fine, finish putting on my self belt and whatever else and as soon as I put in it drive the door speakers and the 10" cut out completely, the speakers behind the heads rest still work. Turn the truck off and start it again and it's fine, I'm lost

As I write this I'm thinking maybe a ground problem? Haven't checked that yet. Anyone ever have some thing similar happen?
