The other day I pulled the back seat out of my 2002 AC Tundra to take some measurements and noticed what appear to be vents in the back wall. They open out between the bed and the cab. I have been very curious about the purpose of these vents. Does anyone know? I have been doing a lot of work on my audio system and was wondering if closing/blocking the vents would improve sound quality in the cab. I apologize in advance if this is a stupid question
