Taha
i am not sure about sound system (not my area)
but floor carpet (1500 - 2000)
Door hardboards (2200 - 2500)
Roof new fabrication ( 1200 - 1500)
But you can do it yourself in less than half cost, near my house there big market of bus and coaster body fabricators, and a lot of shops of rexin (even imported rexin, that you cannot scratch with ordinary knife and is fire resistant also) that costs around 350 rs per meter (its width is 1.5 meters) your car roof wont take more than two meters, and door sheets will also take about two meters. Hard Board used for door sheets is Rs 450 per sheet ( you can cut two cars' sheets out of it) Even imported hard board sheet costs about 800 rs.
Do you understand now, its all pretty easy stuff.
I also have cut hard board to make door sheets (which will be later).
You are in karachi you can get better rates than gujranwala go to busses market you will find variety and cost that will rip your mind. I will try to upload pics of this market and the stuff there and the boards that i have cut.
And carpet for floor is also very easy to replace your can get it from any carpet shop, dont tell them you need it for car, just tell them you need a 3 meter piece (you might get it in cut pieces and on discounted price)
and dont tell us at any later stage that you did not do this stuff your self and got it done from market. :-#
