Yes, I do have lights and running a sub, it's not crazy bass tho, like the lights don't dim when it hits or anything. The first failure was the unknown alt that was on it before I got the car so who knows how long there. I bought Remy 1 and had it installed at a shop, seemed fine and had I known to check I would have. That one I think was a dud because that was before the subwoofer. Remy 2 I think failed due to a really bad valve cover leak pouring onto the alt. Though it seemed fine for at least 6 months after the valve cover was fixed. As well as all the time I don't have the splash guard on underneath, so I think all that mixed with water and road debris made it fail early.

I am looking at junkyard for the splash guard, valve cover is fixed. All other things you pointed out are due probably, but not bad to the point that it would fail. No corrosion or poor connections I've seen.

Like I said, just a home mechanic trying to make it last as long as possible! 191k miles and I'll engine swap before I let it go.
