i found these tweeters which seem like they'll fit under the dash and fit the mounting backet or close enough to do some creative engineering.
found these kenwood door speakers for $20....
found these pioneer door speakers for $25 with a better frequency range...
i might go with a head unit with ipod and android functions since she uses an android and an ipod. she'll love this. there is one for iphone and ipod too, which seems to be much more popular. i guess it depends on what you have for the one you want to get. it would help her with keeping the phone and ipod charged. i like the mount too from amazon for storage.
i'm guessing i should get these...
these are the speakers from crutchfield, which i could get the same head from amazon. since crutchfield includes free brackets and wire harnesses, it would be a little less than shopping through amazon, though i like the head mount and speakers from amazon better.
