Default Kicker ZX1500.1 gate drive problem

Blown up, replaced power supply transistors, drivers, and the driver IC.

Only getting about a volt or so of gate drive on power supply, and 2.5VDC sitting on the gates.

so of course, the SMPS gets really hot super fast and drawing excessive current.

any ideas?
