Right Rear has two (-) connections 7 & 10
Either the polarities are wrong, or the locations are wrong
or my understanding is wrong...
AH, from earlier in the thread I cut some of JesseJamessrt6's post, and this makes more sense even though he includes that image with the labels for the POWER AMPLIFIER A - BLACK 12 WAY connector.

speaker polarity and location according to pin # (thanks ppro);

AMP pin 6 - Right Door speaker input (-)
AMP pin 7 - Right Door speaker input (+)
AMP pin 10 - Right Sub input (+)
AMP pin 9 - Right Sub input (-)
AMP pin 1 - Left Door input (+)
AMP pin 2 - Left Door input (-)
AMP pin 8 - Left Sub input (+)
AMP pin 3 - Left Sub input (-)


duplicated diagram from previous posts showing which pin from the amplifier goes to which high level speaker input from head unit.
