Is my sub blown?

I had thought my sub was blown because it was making a bad rattling noise, but now it has stopped. It is the factory sub in my 03 4runner. I turned up the bass today and played several songs. It'd hit the lows (as good as an underpowered 8" sub will do), and would occasionally have the rattle between notes. I've not noticed this before, so I'm thinking the sub is blown. The best way I can explain it is that it sounds like there is a plastic bag is up against the sub, but this is only at times. Is the stock sub blown, or would there be anther issue?

I've bought a JL amp and JL 8w1v2 sub to replace it with, but if the stock sub was still good I was going to return this and go with something different down the road. It is a DVC sub, pushing an amazing 45 watts so I'm tempted to do the upgrade anyway, but money is tight so if I could do without it'd be nice. Thanks, any other input?
