Hiss is usually a result of gain structure between the HU and amp. The DD-1 isn't looking for hiss but clipping. Hiss is likely with that method. Lower the HU volume used or decrease amp gain or both. Likely you won't be as loud to elimate hiss.

I don't see adjusting passive crossovers as a fix, that is just adding a resistor in series with the tweeter, making them quieter.
