I am new to this site and in need of some help. Searched around but can't seem to find answer.

I have a stock 6cd, 9 speaker radio system in the car. Recently, the battery died and after replacing with a new battery, I am getting no sound from the speakers.

Radio and CD player are both turning on and seem operational but still no sound.

I have tried disconnecting battery and checked fuses but still no sound.

Any help on next steps/options would be appreciated
