So I was listening to music and it stopped for some reason. Upon further inspection I seem to find the problem. It seems that on the end of the subwoofer box (for a truck, with 2 12", long and narrow) the covering seems to have lost its adhesive and the cover came right off. Its the covering for the original box that covers 2 holes. First, is this the reason it stopped? 2nd, can I just get some all-purpose glue and stick it back on, and how would I get pressure on it?
