Pretty Sure one of my Kicker 10 inch cvr's is blown, the one on the Passengers side started makin a really weird rattling noise when the bass hits a certain note??? The other one sounds fine, theyre both running off a Kicker Z750 Amp Should I look at getting the sub repaired? Or buying new subs? PS Theyre both mounted under the rear seat in a 2002 Supercrew Thanks in advance

 

You can probably get a better idea if its blown if you take it out of the box, and manually push the cone up/down and listen for any scratching, etc. If you are hearing it rattle, there is a good chance its nuked, but, depending on how close you are with the place you bought it, you can probably get it repaired/replaced pretty easy.

If you do end up going with a new one, just get the same make and model, dont try to mix and match brands, makes, etc.

Good luck!
