as the title says the front speakers work but the rear speakers + sub dont work. i stripped the rear door to check if there was any broken wires short circuit but its all good i also checked for current but there wasnt any. not sure what is wrong with it

i read that the unit itself has a few bad pins which is why the rear speakers dont work... true?

any suggestions/ thanks
