How do you export logic projects, and into soundcloud without ruining any quality?

Question

I export a song, and it lost alot of volume. I found a way around that by adding adaptive limiter to the entire mix. It helped alot. Now I post it to soundcloud and then some of the instruments quality degrade. And when i play it in iTUNES or even the finder window, it is how i want it to sound. When I hear it on soundcloud, its quality and volume degrades. Is there a way around this???
please help! Thanks!

Just to clarify before I make any suggestions is that what most DAWs call exporting isn't called exporting in Logic, it's called Bounce. If you use the export command in Logic it will give you seperate WAV files for each track and .midi files for any midi tracks you have in your project. The Bounce command is right below the export command in the file menu, though.
The settings you choose when bouncing really depends on your preferences and how big of a file you care to have. If you have no mastering or mixing left to do you should choose PCM saved as WAV or AIFF (I'm honestly not sure of the pros and cons of the two), but you can bounce the project as more than one file format at once so you don't really have to choose only one.
If you bounce to an MP3 go ahead and choose the highest settings which I believe is 320CBR (320 constant bitrate). You can also bounce as AAC, which I prefer because Apple Lossless results in a fairly small file (compared to WAV) while maintaining good quality. You can also manage the file's metadata from this menu so your ID3 tags are good to go.
Like I said it's really up to your preferences and what you are going to use the file for.
