yea tuning is going to be a cast rion bitch. the av8533 I have now has TA and so does the anv7000 so I can do everything with my current head unit then just transfer all the settings to the new one when I get it.

With the subs only getting 600wrms each getting a decent stage should be ALOT easier than giving the subs 1500 each like I was originally thinking. the 5.1 will be a completely other story though. Its going to be hard to find a mounting point for the rear speakers so they wont be overpowered by the subs. Thats something that I will have to figure out when I get the rest of it installed though.
