I would disconnect the AMP, M2, and any other devices from the power wires. Then I would disconnect the wire from the battery hot side. Then, ehck for continuity between the positive wire and ground.
Fuses blow for 1 reason, because the amperage is exceeded. The ways for that to happen is drawing too many amps (that should not be the case) and a short of the positive to ground.
If there is no continuity, then I would check to see that all the circuit boards are not accidentally touching ground. Check the M2. How is it mounted, and to what. Is a solder point touching metal such as a metal case or metal screw that is grounded.
Check the wires, especially where it enters the car through the fire wall, to see if perhaps something sharp has cut the insualtion and is now grounding.
Otherwise, I would run some wire directly to the battery and to the M2 and the amp with out running it through the car, (just jury rig it from the battery to the trunk on the outside of the car) and see if the fuses pop.
Good luck.
