Check all your ground, power, and speaker connections.  Also, make sure that the power lead is sufficient.  I know on a lot of the ford vehicles that have separate factory amplifiers, the fuse rating for the power lead that goes to the head unit is pretty low (sometimes as little as 5amps).

Technically such a fuse would blow before the unit overheats, but if the power lead is like a 20-gauge wire then it's starving the head unit of sufficient current and sometimes makes it overheat.  In that case I'd recommend going directly to the battery with a 12 or 14 gauge fused wire.
