First - The Camaro is in the garage and I am trying to decide whether I work on the system now, save a little more cash and do it later or save even more and buy a set of wheels and just wait on the system.
So, there is the first set of questions.
Second - If I do the system now, I am looking at OEM integration now and adding an aftermarket head unit later...
Here is the wiring diagram for OEM integration:

the question comes in - knowing that eventually I will put in a new aftermarket head unit - do I bother putting in the system now with a LOC or the MX2 that I have (and somehow figure out how to turn on the amps) or do I just continue to sit on everything and wait?
as for gear:
Roadster66
PPI 356cs splits
RSDc 10's
(MX2 if I decide to use it instead of a LOC)
lay it on me.
