Ok, here im lining up, what has been finalised till now from you guys,
REAR SPEAKERS : JBL GTO947 .
AMPLIFIER ON BACK SEAT : JBL GT5-S644
SUB WOOFER : Ami said, I should not go for Cylinder one. So, how about this, JBL GT5-1204BR ??
But cant we go such sub woofers like JBL GT5-S12 , http://www.indiajbl.com/CarAudioDesc.aspx?ID=63 ??
The shopkeer says, for this, we have to make the boxes, which doesnt perform good, so he said me to go for cylinder, which comes from default JBL as the box.
FRONT SPEAKERS : I have no idea, whatsa difference between normal speakers and component speaker system. So, I need some of your help. Ami suggest one , but it costs 7000 and I think, that takes me to 30k, which is way over my budget. I need to stay in 20k.
yeah lol,thats the sad story and all of my 4 speakers now have inbuilt tweeters. HA HA HA!! Now I have 4 Blaupunkt speakers,which are 165 W each and 2 are on rear and 2 on front .
Can I just use those 2 speakers on the front door as it is now and use AMP and SUB WOOFER for rear speaker ??
Or do we connect the front spekaers also with AMP ??
bro,

Tweeters are already present in your blau speakers. 
Components will have tweeters. For a complete audio experience a tweeter should be present.
If you are not adding sub/amp then simply adding the blau speakers would be fine.
