get pioneer 5250SD head unit. it has usb, ipod, iphone and memory card option. should cost around 13000. it has sub control as well for future upgrades. if you dont want to have a sub, i think 4150 has the same option with only 2 RCA. get fusion components and any 2 channel amp for the components. if u get 2nd hand pre or a pre with 2 RCA out, it might be cheaper.
@manofpk
bro u need an amp to run the components. for speakers it depends on speaker to speaker. e.g. kenwood 718 dont work properly without an amp but pioneer 6902 can work with or without an amp. adding an amp of course increase the sound quality if your speakers are 50 watts RMS and above.
