The treble strings sounds louder than the bass ones.
Do you mean when you play the bass strings with your fingers or with your thumb?
I'm self taught and for years I played bass notes much too quietly with my thumb (in relation to the treble strings). When I finally heard a recording of my playing, I realized the bass melody wasn't pronounced as it should be. It took me a while to figure out the importance of rest strokes with my thumb (I always use the fleshy part of my thumb).
I also occasionally find it useful to use my thumbnail with a slightly softer stroke to match the sound of my other fingers as well.
Its very important to coordinate the power you put into the strokes. I now carefully imagine the power I want to put in each stroke before I release, and most importantly, feel the tension released after each stroke, so that each finger is relaxed again and does not stay tense during a quick passage.
If you mean your i m a fingers aren't producing good tone on the bass strings, try turning your hand from the wrist more towards the bridge (John Williams Style) so your nails don't scratch down the strings and make that rough 'rrrip' sound. I try not to use my fingers on the bass strings unless it's necessary.
Hope some of this has helped!
