So first you need to do is to check if you have connected those RCA wires correctly as it is the audio output from the Pumpkin headunit to the original car amplifier. They are two method, please try another others if the one you use do not work or output lower volume.
S2,If all connected correct but there is still no sound comes out from the rear speakers, please check if you have set the Amplifier field wrong in the setting.
S3,if the rear speakers just lower than the front speakers,you can adjust the output volume rotary knob in the "amplifier box" to the prefect level .
S4,If those are correctly setted, but still not luck with the sound, then you may need to use the following small parts to solve it. It is called LOC(line out converter), you can buy from your local or internet, normally cost no more than 10USD.
And you need to manualy joing the wires to the REAR speakers wire from the Pumpkin headunit's harness. And the RCA side connect with connector A and B from the previous image shows.
