Hello, I got my frist mark VIII ( 1998 ) It has the JBL audio every thing works good. Well it did till I tryed to play music with any bass. I have 2 of the speakers popping bad. The 10 disk player works great and I don't want to change any of that. I guess what I need to know is how hard are the door and rear speakers are to change. Also what size are they I have been told 6x8 or 5x7. I think the system would sound ok with just a good set of after market speakers. is this some thing I should try or take to a shop? Thanks
Mike.
