beginner sound system questions, would appreciate any feedback Options

hey guys im i beginner to the whole celica car scene, being that i'm only 16 and just got the car not too long ago. but i have been highly interested in import cars for 3 years now.when i bought the car, the front speakers were mostly blown so im thinking of replacing them. at first, i was thinking of getting components but realized i dont have the $ right at this time. i started looking at some 6 1/2 pioneer TS-A1680R 4-ways 2-50w rms. i dont like brain busting bass, but like to hear some decent bass every once and a while. i dont realy want to take up any trunk room so im not thinking of subs right now. so i have a few questions:
1) has anyone heard anything good/bad about the pioneer tsa's above
2)should i buy 2 pairs, since they are only $70 a pair at sounddomain.com, and later buy a 4 ch. amp to get the decent bass im looking for once in a while
3)should i buy one set of the 4-ways speakers to get the highs and a pair of components to reach the mids and lows
- and if i did this could i set up an amp to power all 4 speakers if it were a 50w rms amp?

id appreciate any info possible.thanks for checkin this out and hope to hear ur replys.

well if you go that route Id suggest you look at the threads on buying electronics. I paid 250 for my amp and afterwards bubmled through the list of sites and found it for 200 (new)
