I have a 98 durango I recently replaced the heater core. After I had everything put back together I had front speakers then they quit working. I checked the plug behind the radio and nothing then I checked the plugs under the dash the plug by the parking was loose I pushed it in and the front speakers started working. Now they stopped working again. I checked both plugs and still no sound. I checked all the plugs I could see and still nothing. Is there another plug somewhere else I’m missing and should check?

No. Sony radio about a year old. Boss speakers from Meijer. I think this weekend I’m gonna pull one of the front speakers and take it to the radio and see if it works. I have another radio I could wire in to see if it’s the radio. Just kinda blows my mind that both front speakers stopped working.
