I have never owned a mustang before or a convertable but I do now. I got a 2004 40th anniversary edition convertable. I don't know much about it the previous owner installed a after market touch screen stereo it's a cheap one. However or works fine so I don't want to change it my issue is there is no good sound. The rear speakers work but no boom at all. I was thinking about replacing the speakers but have to clue how to take them out. There is a felt like cover over them but don't know if I should pull that off or not. Thanks
