If you're doing the head unit alone don't bypass the AFBS. ONLY bypass it if you have aftermarket speakers.
In regards to iranman's case I don't know what the hell's going on there, but that's the first case I've ever heard of that happening.
jbx if you want a write up on how to do the bypass let me know. I was going to do it a while ago but I didn't think it was was in high demand so I didn't do it. I have all the pictures and everything ready.
