    Where is your gain set? Chances are you clipped the amp by turning it up too far and fried your sub.

    More then likely the raise in the remote control bass is what did it, more then likely distortion had set in causing the sub to go since distortion is a big killer in subs, and if you had it in the trunk you might not of noticed it happening since the back seat usually acts like a distortion baffle!
