Mrs. Doghauler here. Thank you for your reply, Stamp. The Expedition is my primary vehicle. We traded my Mountaineer for it last Friday. It sounds like my DH might have misunderstood me. The speakers in the front doors don't cut out. They fade in and out. It doesn't matter if I'm pressing on the gas or not and it happens no matter what I'm playing...the radio, a CD, etc. The back speakers are fine but because my dogs will be riding in the back crated, I don't want to subject them or their ears to our music. I'm taking the truck back to the dealership tomorrow. Any suggestion(s) on what I can tell them to look for?
