I have a 2011 Audi A3 2.0 TFSI Ambition 8P Automatic Convertible which originally had a Symphony double din radio/cd installed. I decided to replace it with a Kenwood DMX8020S I also installed
a DRV-N520 Dashcam & Two, one rear & one front normal camera's. Everything works great but the back speakers and sub are half the volume of the front.
I have been told the RCA out are the problem. They are made for aftermarket amplifiers & don't supply the correct output to power the...
