Depending on the model of your Mazda 626, your stereo system may come with the optional Bose sound system. This will typically include a double DIN factory stereo and a CD changer that’s mounted in the trunk. Eliminating the double DIN OEM radio is easy to do, from there you can use an install kit to mount your single DIN stereo.
