10k is decent amount for good components.
Cruze takes in 6.5" at the front if I am not wrong. For online purchase, look nowhere else than Snapdeal. Snapdeal houses original products at competitive (400-500 rupee difference from market rates) prices, which I don't think other websites do. Other sites like ebay.in allow sellers to sell whatever they have (whether original or fake), so stay with Snapdeal only for this purchase.
Did a quick search on Snapdeal and found these components under 10k.

You can get any of these except Sony (not VFM
) and 5.25" Polk 5251 (priced higher than market price). You can avoid Alpine also as there are a lot of chances of fake Alpine speakers. Hertz has a sweeter tone and JBL has a good balance, Pioneer is good if you want more bass. Polk DB6501 has some really good reviews online and is an awesome product, I have heard it and it handles bass as well as vocals much better than JBL GTO components. You will like Pioneer and Polk for their bass response and quantity! JL Audio products are new in India (especially for mass market) and I haven't heard them either, so no comments.
You must audition as much brands as possible from ICE shops before ordering one online.
EDIT - Focal 165 is also good but I think you will already be having this set currenty.
