1998 Mazda 323 Repair Question
First, were the belts bad when you replaced them or did you just do it to eliminate the noise?
If they went bad very quickly, then you have an underlying problem that needs to be fixed. It could be a bad accessory on the engine (pulley/bearing) or the belt tensioner is bad.
If you just replaced them to chase down the noise, then you should make sure the tension is correct and that the tensioner is holding the tension when the engine is started.
Keep in mind, sometimes belts make these noises in very cold or wet conditions for the first few minutes and there isn't much you can do about it. Buy high-quality belts; they make noise less often.

I can't really see what your engine looks like without looking at one directly. But if you have a serpentine belt, then any accessory on the engine can cause it to fail if one/more of the pulleys are freezing up.
If you have powersteering/air conditioning, or the tension pulley can cause a belt to go bad.
If you don't have a serpentine belt (V-Belt), then either it's too tight, too loose, one/more of the accessories hooked to it are bad or there's water/oil getting on the belt.

Check the crank pulley. It is equipped with harmonic damper and when the dampoer is bad, it would result in noises, burning rubber smell, insufficient charging and premature failing of drive belts.
Note if the crank-pulley is moving in a wavy pattern, especially the inner ring where it drives the alternator belt.
