Turntables ground to mixer. Mixer connects to pre power, 2x4 sits inbetween with jumper cable with outs to power amp and powered sub.
Any issue there?
Loosen off your phono plugs, you may find they’re making contact with the case and creating additional ground loops.
Start at the power amp and work your way backwards.
