thanx for the suggestion buddy ....but how that alpine pre in comparison with 5250sd and what will you suggest if i go with all pioneer things?

Sir Pioneer 5250SD is much better then Alpine CDE100 but will cost you at least 4K Rs more, Alpine will get the job done in your budget.
You can get all Pioneer but it will cost you an arm and a leg, all pioneer products are not best, so its no good.
Kenwood 3012 is better in sound production (I can confirm that for sealed enclosure) then 308D and also in build quality, also look for these SUBS, if you can afford, they are the best at a reasonable budget.

A 4 Channel AMP will either power your front 2 components with 50-60W RMS or the same power to rear 2 6 X 9 speakers, remaining 2 channels of AMP will be bridged to sub for a combined power of 100-110W RMS depending on the AMP and the remaining 2 front components or rear 6 X 9 will be powered by the Head Unit.
In future you can buy a dedicated Mono AMP to drive the SUB with full power and the 4 channel AMP can power your pairs of front components and rear 6 X 9.
Do not go for a 4 Ohm SUB.
Get a good tuned enclosure or a sealed one with a 5/8" Lasani or good MDF with around 1cuft or 1.5 as per the SUB you like.
