Im looking to replace the 1" tweeter and the 2.5" midbase speakers in my 2000 BMW 323i. I just want something that sounds decent without spending much money at all. No high end stuff here. Something with decent sensitivity would be great as I am likely going to reuse the stock amp.

I'm also thinking that I should replace the stock 6.5" paper cone speaker with a cheap 6.5" speaker that wont melt in the rain.

Any help would be much appreciated.
