here in the near future, i will be glassing my doors. my original plan was for 2 7" and a 1" tweet per door. going active via my 860 in pro mode. i've been thinking lately about doing 2 7's, 1 tweet, and and a 4. i want this to be very clear, and loud. what would i need to do this? any better suggestions? i want to know EXACTLY what i'm doing before i start.
