Query: One of them blew within a day.

I bough these with no expectation of them being high quality speakers. They were just something to replace by tired old stock speakers in my '97 Wrangler. However, after only one day (and no more than 3/4 volume from the stock radio) on of them developed a noticeable crackle. I guess I'm not surprised, maybe I even broke it putting it in (doubt it). But, in the long run I'd say you usually always better off spending a bit more to get something better...someday I'll learn.
