Ok, after careful research I think I've finally decided what I'm going to use for my build.
Source: Fujitsu Ten Stock, eventually replace with Ca-Fi Knock-Off
DSP: Audison BitTenD
Amp: Audison Voce AV 5.1k
Interconnect: Audison AV bit IN
Drivers:
Audible Physics NzA Duo's
Other than a sub I think that will do it. I plan to utilize the factory mounting locations with adapters. As for the transducers I may A pillar mount those, or attempt to fab a bracket to use the factory tweeter location. Using the BitTen gives me quite a lot of options for tweeking. This will hopefully give me excellent staging.
