So the guy came by with the car and the whine disappeared after grounding the HU with some copper wire like in the pic...
Re sound/clipping it was just a bad tuning on the part of the shop guys. Got rid off the +6 Low/Mid/High on the HU as well as Loud
We spent some time fiddling with the HU at high volume while moderating the amp gain till it sounded just right to his tastes. Ran the HPF on the HU at 50 as it suited him.
Iv suggested a 75.4 to him at the time he adds a sub so that the system is more efficient.
