Yep.  The car environment is pretty rough with very high and very low
temps. plus humidity.  It is entirely possible that the cone has warped
slightly causing the voice coil to rub - this makes the fuzzy noise.
It is also possible to warp the basket of the speaker by mounting it on
a less than flat surface and/or overtightning the screws.

If switching the speaker leads (switch left & right) doesn't cause the
fuzz to move to the other side of the car, you can be sure it's in the
speaker.  If the problem moves, then it is in the radio/tape unit.

If the speakers have a long warantee, you might get a free replacement.
I know that most home systems have at least a 5 year warantee but I
don't know what car speakers typically have.  Good Luck.
