Sorry took me awhile to find the thread again.
Check and see if you have the same colors, but output to speakers after the premium sound amp, goes like this.
T/Y- tan/yellow stripe LR+
PK/LG- pink/light green stripe LR-
O/LG- ornge/light green stripe LF+
LB/W- light blue/ white strip LF-
PK/LB- pink/light blue stripe (can't read the LB for sure) RF+
BR/PK- brown/pink stripe RF-
DG/O- dark green/ornge strip RR+
W/LG-white/light green stripe RR-
Hope you can sort it out from there.
