The Nissan Path

Hey All - just wanted to know - what specific tweeters can i buy to replace the ones that come with the vehicle? You know the ones that go in the pillars by the windshield. I'm looking at changing the Bose system so just need some advice/info.

Want to try and go with an In dash DVD player. 7" touchscreen and so on - do i need to change the door speakers too? i hear some people say that the Bose speakers don't work with some aftermarket stereos. But anyhoot those are easier to change i guess.

Thanks

would you consider selling your factory raio? if so how much do you want for it?
