hello there,

i just purchased my first volvo two days ago and am so happy. 167k miles, perfect condition. only two owners before me. my question is in regards to sound system upgrades. especially the speakers. from what it looks like, it looks like the doors are 5 1/4 and the rear are 6x9 perhaps? i've read on other forums that alpines seem to fit the best of all the brands out there. would love any help to point me in the right direction, as well correct me if the dimensions for what i think the speakers are, are actually different.

thanks...
