HELP!

So, just for my own self pity, if i turn the bass on my head-unit up and leave the volume at a relatively low level and isolate each speaker individually (right-front, left-rear, etc...) and each speaker gives me a really annoying rattling sound, that's a fair sign that they all need to be replaced correct?

I have the infinity sound system in my 04 dakota 4-door.

In the case that all 4 speakers are blown (I believe the tweeters are okay), can anyone recommend me a good solution to getting decent sound back for cheap. I'm not a music freak, and don't even have an ipod (yes, I listen to the radio) but I would like to be able to listen without the rattle. I am looking for a cheap and easy to install fix.

Thank you in advance!
