Logic Pro 9 Volume/dynamic problem with bounce

[Brentandang]

When I bounce my output tracks from Logic, the volume seems low and it loses some of the dynamics. I bounce to aiff/mp4 file. I tried to change the dim level but no change. My brother records in GarageBand and his songs sound louder and more dynamic when posted to Sound Cloud.

Try and load one of the channel strip presets for premastering, or add some compression and limiting on your master output fader.

Also make sure you aren't turning down your master fader by accident.

I can understand it losing loudness (if as George says) there is some problem such as master fader, but it should not lose dynamics.

One way to test things is to import the mix back into the project, play back on a channelstrip with the phase reversed (gain plugin will do this) and see if it perfectly cancels out the sound of the mix.
