recently replaced my stereo system and two rear speakers, are any in the door?

How do I do that if I have to, and can they not just be disconnected?

Thst is not what you ask!! Simply turn the speaker fade to the rear speakers only,, if you dont care about stereo sound! Why not FIX the system? Speakers dont cost that much, it's your car, do what you want to!!!

When I had the new system installed I just replaced the rear speakers. I am going to call best buy and see if your suggestions could be the problem, thank you
