[QUOTE="Mike Pfeifer, post: 6201864, member: 613312"] Hi, I'm new here, but have been into car audio for a long time. I bought a DRX9375R years ago, either in 97 or 98, dont remember for sure. I still have it and was thinking of installing it in my current car, but I have a problem. I need an auxilary input as I have a PC under my passenger seat that has all my music on it (touchscreen in dash, etc.) I have searched the net and found that it's next to impossible to get audio into the H/U unless you hack the C-bus cable and run a dummy CD changer while audio is coming in through the C-bus cable from the aux source. Now, I have a DPH7300 processor as well. I am wondering if there is a way to get an aux input with this in the system as well. So what I am thinking here is that I can wire up a simple RCA 2 pair in / 1 pair out switch, and just flip a switch when I want to listen to the aux source.
