Picked this up today from Steve at AmpMedics. Traded the previous owner my Skar Sk85.4 and paid Steve the $220 repair bill. Had a full ovehaul. Changed fets, drive board, and power supply! Having Robin at BHE build me a set of double stack Fi Q motors into 12's with PSI Soft parts next month to run on this bad boy. Can' wait! And my Q motors. (Yes I know one has cooling option and one don't. Both NDMstang65 and David from PSI have given the OK to run them as a pair.)
