I got a 04 Isuzu Ascender, and I already put in a new deck and amp, but I need to replace those old speakers. But I can't figure out what size they are! Everyweb site I visit says that they are somthing diffrent from the last! I think they are 6.5 components in the front and 5.25 in the back. Can anyone confirm this? and can I put a component speaker in a non-component place?
