Looking for some help and advice. 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 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?
Would really appreciate some help.
Thank you
