Looking to upgrade the Titan

Have a 04 King Cab LE 4x4 and starting to collect parts for it. I decided to fix it up some when I was looking at new trucks the other day and WoW!! Expensive. Thought to myself there is nothing really wrong with the Titan, it just needs a little upgrading. Here is what I have so far. I plan to round up all parts then do it all together.

RC 6" w/RC traction bars showed up yesterday
Kenwood DNX 892 navigation w/metra kit will be in Monday
Kicker KX800.5 will be here Monday

Still need to get the following

Looking at 6.5 Focal components for the 4 doors and 1 10" subwoofer image dynamics????
20x10 Fuel Mavericks with 35x12.5 Toyo???
Plan to replace factory leather with Katzkin

Looking to have complete by the end of the year.

Last will come fresh paint. The body is almost perfect few dings nothing serious.

Any suggestions on speakers i would like to hear them
Thanks
