So im driving down the road and notice that the bass isnt hitting as hard as it normally does and i suspect that only one sub is hitting. I get home and inspect the box and sure enough only the right sub is hitting. I checked all the connections and everything is fine. I was going to go back to bestbuy to see if they can find out what the problem was, but the left sub started working again.

So i drove around with both of them working for about a day and then the left one cut out again. I got out to look at it again and pushed the sub in and out and it felt normal. Then i grabbed the cap in the center and pulled outward and the sub started working again, then stopped. Is the sub blown?
