Hiya Mr Singh,
First the F1 screen i having on top of the air vent is the old F1 series the TME-M790, not the new one, i had this screen for almost 1 1/2 years, this was mean to be the main screen for my car, but damn Alpine bring out the new IVA-D300RB this month, so i got that for the main screen instead, and i though it will be a waste not to install the old F1 screen as well, so that how it end up on the top vent, hehe it will be running together with the new RUC 700 & PXA-H701 Multimedia manager..
for audio side, i will be having the Phoenix Gold Xenon series 6.5 & 5.5 inch Comp speakers, also will be using the PG Xenon 12 inch Sub too, of course amp will be from PG as well.
as for the power supply, im running a dual charging system with a 2nd Exide battery in the boot..
