Question: Belt keeps Shredding...

My belt keeps breaking on my Pontiac Grand Am GT V6 3.4L. I have replaced the following in order to fix it: Both idler pulleys, pulley tensioner, alternator, power steering pump pulley, and removed and reinstalled after inspection the crank shaft pulley. I have not removed it but the air compressor pulley seams perfect. When I look down through the engine it looks like the air compressor and the crank shaft pulley are not lined-up, but I am almost 100 percent sure they are installed correctly. Any ideas? Any help would be greatly appreciated. Thanks!
P.S. My belts don't break they shred...

It goes without saying that these pieces wear out, but they do so slowly, meaning you may not notice they need attention until ...
