So I've successfully taken out the stock radio, and put my new pioneer double-din FH-X720BT in its bracket. I tried testing it out and the stereo powers on, but theres no sound. I have the ground, battery, and ignition all wired up. (red, yellow, and black wires) I can't figure out where the rest are supposed to connect to. There is a blue/white cable on the wiring harness which is the amplifier turn on, which im assuming needs to be connected, but there is no blue/white wire on the aftermarket stereo except for the antenna. Could someone please help me figure this out?

The Blu/wht, is unecessary. That is for an aftermarket amp, and system if you ever add one.
I noticed the Blue isn't tied to anything? IIRC, that one has to be wired up with the power antenna on from the HU as well. This is like a secondary signal for the deck to know when to run the radio, otherwise it won't turn on that function. I had no radio recently when re-doing an old subwoofer install on my current subaru and trying to use that as the signal wire since the amp turn on is only 5v.
All I can recall was actually wiring up the RCA's and 5-6 of those individual wires. The Blk/Red/Ylw/blu/orange for the illumination. That was all I needed to do, I'm fairly certain.
