Hey bone, you have posted the following brands: jbl, infinity , sony , pioneer , kenwood , alpine , jvc You have spent Rs12000 on the Head Unit. So you are left with Rs13000. My recommendation is the following: First, select a good installer that does the justice to the word "ICE installation". Now, for Rs13000, I will do the following if I am you: Front doors: 6.5 inch JBL Components (upto Rs6000) Rear Doors: 6.5 inch JBL Co-axials (upto Rs3000) Damping Rs1500x4=Rs6000 (Its worth the money believe me). or you can forget the damping part and go for Infinity Kappa components in the front and infinity/JBL co-axials at the back. Just make sure that the front speakers are comps and rear are co-axials.
