Got my new truck today. '13 F150 STX 4x4 Supercab.

To say I'm ecstatic would be understating it, coming from a 2006 Malibu.
Not sure what I want to do with the audio system. Everything is so integrated I really don't want to mess up the SYNC system since I think it integrates with my smart phone to give me check ups on systems.
So that brings me to the question: How would my system sound with the OEM HU, with a processor such as an Audiocontrol, BitOne, MS-8, etc., with external amps and new speakers.
Can I keep the SYNC functionality if I throw in a new HU? I imagine I would need to get a steering wheel control adapter, and I probably would lose some buttons from the OEM HU.
Will swapping the HU or adding a processor void my warranty? (reading up on this myself)
Otherwise I will already adapt the doors for 6.5 components as long as I have room. Also not sure about subs. I kind of have to fold up the 60/40 seat. I could fold up the 40 side, and have room for a small box, possibly a ported 12. Or I could fold up the 60 side and have a longer box, possibly fit a 15 or 2 10's or 12's. I really would prefer to lose the smaller seat so I have more cargo and passenger room.
This will be an offroad vehicle. So I want to be sure everything won't be bouncing around. I may not do all these upgrades immediately, but definitely soon. Cheap factory systems just don't cut it for me anymore. Except it does have tweeters in the A pillars so it is bearable and will hold me over, just nothing crank worthy.
