So I did a little research this afternoon and it's kind of a surprise to me to find out that low volume on AUX inputs with automotive head units seems to be something of a common problem. Much more so than I would have guessed anyhow.
After you check everything out and if you don't want to try the inputs on the back of the unit, it looks like you can add a small headphone amplifier before the AUX input to boost the gain signal.
A brand that I have used in the past and I think are good quality come from a company called FiiO. The FiiO A3 and maybe the FiiO A1 would do the job and keep the cost down. Amazon has them, Parts Express, ebay, etc. It would not have to necessarily be the FiiO brand.
You would come out of the audio extractor and plug into the amplifier and then out of the amplifier and into the AUX input.
Set a volume level as a reference with the CD input. Then switch over to the AUX input and turn the small amplifier volume up until it matches the volume level of the CD input.
There is also a company called "Sound Shocker". They build a small amplifier exactly for this problem that you install in line the same way. There are some YouTube video's showing the Sound Shocker being used in cars.
