Advice for Car Player and Speakers

Hi everybody!

I'm asking for your kind help as I am going to replace my old Clarion head
unit.
My budget restricts my choice a lot, after some searching this is the list I
have:

Clarion CD7000
Clarion CD7100
Sony CDXGT20
JVC KDG432
Kenwood KDCW241AY
Kenwood KDCW3537G
LG LAC 3700R
LG 4700
Pioneer 2900
Alpine 9871R


In your opinion, which one is best suited? I am especially interested in FM
quality and Mp3 capabilities.
Then the speakers choice comes...What do you think about Sony speakers? Are
they crappy or comparable with JBL or Boston speakers?
Thanks a lot for your kind replies,

Kaplan
