Hi Steve!!!
congrats for this amazing build you are doing... only 2 question:
1) why the tweeters hidden in the doors, and not in the pillar? you'd have a sound stage 100times superior with a sound quality unbelievable...
2) the mids (per door) work one in closed box and one in door or i mistake? if yes...why this solution?
sorry for the questions...but i follow you for a great time
