@ nickandre , @neil : Done ! After a lot of thinking, I have decided will go step by step on some quality Audio Upgrade instead of just putting up some c**p in a hurry.
First, I'll upgrade the 4 speakers.( Budget 10 K )
Second, Put a good 4 channel Amp for the speakers ( Budget 7-8 K)
Along with wiring, fitting charges, this comes to 20K. And I think this will give a decent sound. I'll go for a sub and a mono-amp for the sub later.
Now, what is the wattage/rms of the OEM speakers ? I'll replace all 4, done ! Which are good speakers i'll get for 10 K ? (can i get rockford fosgate for 10K , all 4 ??).
Secondly, Can I get a 4 channel amp from rockford fosgate within 8K ? If not, JBL is there for sure. But will it work well with Rcokford/any other speakers ? Or is it that all the stuff (speakers,sub,amp has to be of the same brand) ? Which speakers of rockford/JBL GTO series/Infinity will directly fit into OEM speakers ? Will there be any difference in quality of music after fitting 4 new speakers and a 4 channel amp for the speakers ??How will the fitting/wiring be done for this? I am more keen on rockford fosgate or JBL GTO than any other brand. These are good.

1. Speakers :-
your budget is almost same like mine... I have 10k budget for 4 speakers . As you have no provision for oval speakers in verna in doors , you must find a round speakers.
there are very less models in Round that comes with 3 way - [Midrange woofer + speaker + tweeter ] most of the round speakers are 2 way that doesnt have tweeter in it.
I have searched in hertz/polk/rockford for Round 3 way. there are very few models but all of them are very high priced. In those brands you will only get 2 way speakers in 10 k budget.
Then finally i came down to Infinity kappa 63.9i -click this - Infinity - Car Audio
It's 3 way and has 75 rms and my sony amp output is 80 rms. almost matched. 5k for 2 speakers so 10k for 4 .... Done!
2. Amplifier
JBL - Product Support - GTO-504E - 280-Watt 4-Channel Full-Range Amplifier
It has 70 rms * 4 ... almost matched to the above speakers which has got 75 rms.
This amp has got every single feature that we need for speaker. It has Freq setting + low pass/high pass filter for all 4 ch + bass boost ..
you need to set your amp at high pass filter if you are using speakers and if you are using sub then low pass filter.
The another benefit of this amp is -
we have got 2 preouts from our stock head unit. Both of them are used in your front and rear speakers. you still need 1 more preout if you are planning to add subwoofer later on. To do so , you must buy an amp with preout. and this amp has got 1 preout in it. to which you can connect your subwoofer via monoamp in future.
This amp should cost 8-9 k Done !
3. Subwoofer
never buy sony sub. i have replaced my sony sub with infinity 1260w . Sony dont sound good. i still dont prefer jbl subs too. In rockford and all , good subs cost too much.
Best is to buy Infinity reference series {the one i have got is- infinity ref 1260w}
Costs - 5.3k
OR better one then - infinity kappa series - 7k
4. Monoamp
now this will be the costliest thing in your whole setup. you wont get any monoamp below 10k price except the sony monoamp [9k] which is again crp stuff.
I prefer this -http://www.jbl.com/HI-IN/Products/Pages/ProductDetails.aspx?PID=GTO3501 should cost 11 to 12k.
Instead of buying two amps , you can buy Rockford 600-5 the one that nickandre mentioned. but then the question arise , you have only 2 preouts in head unit , from where you will get the third one for sub if you use rockford 600-5 amp.
You need some converter and all for that but it will decrease the performance.
5 Subwoofer box
Every subwoofer need different size of box. for best , before buying sub box , read the manual and see how much cubic ft. box is needed for that sub. my sub need 2 to 2.25 cubic ft area of box.
There are difeerent types of box too. --> http://www.mobileinformationlabs.com/HowTo-1Woofer-BoxPaid-New.htm
according to me - ported(vented) boxes are best as they can handle lot of frequencies then the sealed one. sealed one gives you hard punch only but they cant handle some higher frequncies. So go for vented box.
Thanx
