Can someone help me please I just installed the decoeder board into my car, i connected the speaker outputs from the decorder board to the Aux input on the cars head unit. Im getting alot of crackling coming through the speakers there is no humming noise. i used the cigaret lighter socket live and ground to power the decorder board as this is fed by the cars acessory circuit. on the decorder board the left and right speaker outputs have positive and common wires i only connected one common wire as my Aux input only has one common connection. how can i stop this crackling noise
many thanks in advance Ps if i connect the two commons together on the decorder board there is no sound output this is why i only connected one and not join them together

Do you have a speaker that you could connect to each speaker output, one at a time, to see if it produced clean audio?
I haven't measured that yet. Because i was not sure if i could use it. The manual says to use a amplifier if i want to use the audio output what dc voltage is ok to connect it to Aux input
