Amp2 with USB HDD

I am using HifiBerry Amp2 with Raspberry pi 3B+ with connecting 3.5TB USB harddisk and supplied the 1.5A 18VDC power to Amp2 only no power to Raspberry Pi. It works ok when playing network resource, but just frozen when it try to access USB harddisk.
It looks additional current drawn to access harddisk.
Can I supply 5VDC power to Raspberry Pi even I already supplying power to HifiBerry? If so, isn't there any confliction in between two power supplier?
