Looking for some help and suggestions. My car radio unit has a built in amp and has 8 wires going to 4 pair of speakers. It also supports a 3.5mm audio aux input. However, the 3.5mm aux input is treated as a source and I can only hear it when I'm in that source itself. So if I'm listening to the radio or any other source then I cannot hear the sound from the aux device. I need to somehow hardwire my aux input signal directly into the amp so that it mixes straight into the radio regardless of what channel I am in. Can anyone help advising me how I can even begin such a task? I'm thinking it would have to be mixed in somewhere in the amp inside the radio but have no idea where to even begin. I have a spare radio that I bought from a junk yard but the amp is blown on it so not sure how I can test.
Would really appreciate some help.
Thank you
