I modified my car radio to switch between FM radio or a stereo aux in (using the stereo radio lines to a sound fader chip)
The problem I have is the AUX is not as loud as the radio and when i turn my mp3 player up it distorts badly.
I use a 3.5 jack connector which switchs between radio / line in.
The jack wires connect to input pins on the sound chip TEA6320

I've read I need to put 4.7k resistors in the AUX L & R, but testing with 1.5k and 10k proved it didn't work.
Any ideas how I can get the aux to match the radio volume without distortion?
Thanks in advance.
