Going from
a single ended output to a balanced input with no isolating transformer
won't be helping.
I suspect the OPs "speaker wire" is probably an RCA cable with a mono 2
pole TRS adapter on the end.
What connection that is making within the 3 pole TRS input is anybodies
guess.
Presumably pin 1 screen, pin 2 hot, and pin 3 bonded to pin 1.
Maybe the XLR shell also bonded to pin 1.
