Buying Speakers. need advice. Options

[Badkarma]

i just sold my mustang, and i have some money to spend. im looking to get a new head unit, and some speakers all around. right now i have the stock speakers, tweeters, and some random cd player.

i want to get some great quality speakers. that fit in the stock holes. (6.5's i believe) also, what is a good head unit? i don't want to get an amp or subs.
living in houston if i have subs and amp it would be gone in a week... i appreciate the help.

also, should i replace tweeters? or should i get speakers with tweeters?

looked at some polks last night. they sounded great compared to whats in there now. this was at circuit city btw. never heard of components tho. my boss is giving me his alpine deck tho. i think its a 7 series.

what about tweeters tho? tweeters seperately? or combined with the speaker?
i'd rather stick with one brand front and back. i have enough money. i just really don't want any subs yet tho. maybe if i get transferred out of houston for mercedes ill get some then.
