Aloha Jayson,
What I've learn on how to project your voice is to imagine you are singing to a person that is far away from you or at the back of the crowd. Singing is like anything else you learn, the more you do it, the better you get. Sing in the shower, normally good accoustics in there, and try to project your voice so people outside the bathroom can hear you, but don't sing in a shouting manner. A voice coach can help, or in my case the church choir leader.
I hope this helps a little...........................BO......................
