This is what I used for my E30 stereo upgrade.

Here goes:

5 1/4" Boston BACRC51 for the front (these include the tweeters) 5 1/4" Boston BACCX5 for the rear (two way speakers) 2 10" Boston BACRS10.8 subs for a custom box in the trunk I had an old amp that bridged mono to 200 watts so I used that. Head Unit is a Clarion CLADRX6175 w/CD in head unit but also has capability to run a changer. This unit is probably discontinued by now. But the replacement should do.

Speakers, as I've said before, are very individual! What I like may not be the same as you. For instance, I don't want overpowering bass for rap music but I do want to hear those low I went with the Boston woofers.
The tweeters are excellent, the best "I've" heard. If I did it again I would have gone with the same speakers in the back as the front and left off the tweeters and used an high pass filter. The highs should come from the front. in my opinion.

the whole system, without amp for sub, ran about $1200 worth every penny, esp in a convertible!(where you lose a lot of sound)
