I’v the same hardware. The Raspberry is very critical on power consumption from the USBports so I feed my 2.5 harddisk (0.95 A) separate with a 1A powerregulator (TSR 1-2450). You can connect the regulator + en – parallel on the amp and the other + (5V) goes to the 5V display pin. The – you already use. Be aware of the little rainbow in the right corner but this can be switches off but I do not know. With m2p there is option for this.
