What's up guys? I have a 2007 Chrysler 300 C and I recently installed a cheap double din indash. I got picture but no sound so I did the amp bypass but I want to have my factory amp so i ordered the rp4-ch11 harness. It is supposed to let me retain my factory amplifier along with my steering wheel controls however after hooking it up I still have picture but no sound. HELP ME😭
