Just picked it up this week...
I have the following equipment from my previous build that I will try to recycle if possible:
(2) JL 10tw3s in a sealed box
(2) Zapco st-x amps (4 channel and mono)
AudioFrog GB10s
AudioFrog GS40s
AudioFrog GS60s
MiniDSP
Fiio x3 DAP
I'm thinking about getting the AudioFrog GS690s as the doors have 6x9s from the factory... The rest is yet to be determined.
