I have a 2010 town and country with the ves system but no subwoofer. My first question is does anyone know the part number for the subwoofer that goes in the rear where the jack is located or if anyone makes a after market setup that fits in that location? Next up my children broke both sets of headphones and I need to replace them but was wondering if i can use any other brand of wireless headphones or if I am stuck using the chrysler brand. Any help would be great .
