Figured out a solution and it works great. Running 2 Alpine KTP-445U 4 channel amps now. Apparently the dash mid and tweeter were on the same channel, so it is connected as such: Left Dash Mid/Tweeter Channel 1, Right Dash Mid/Tweeter Channel 2, Left Front Midbass Channel 3, Right Front Midbass Channel 4. The second amp is: Left Rear Mid Channel 1, Right Rear Mid Channel 2, Left Rear Midbass Channel 3, and Right Rear Midbass Channel 4.

Sounds great with the new BSW Stage 1 kit!
