Cables are made... labelled with both ends being differently labelled... dsp end has letters to denote channel on the dsp, other end is numbered for zapco channel number... both ends contain designation... ltw, rtw, lm, rm, lmb, rmb, sub is orange currently but will be silver ones right angle adaptors arrive and the signal cabling will be complete the 3D printed cable holder for the amp end is a work in progress and will be developed but as an exercise it worked a treat and held cables to the rca inputs both secure and straight!
if anyone wants the stl for 8.5mm cables drop me a pm... very simple to make and a 5hr print 3D printers are awesome albeit a bit slow... it’s done in petg for heat resistance
