After reading much about this subwoofer and it dying all the time for people I am afraid this will happen to me. I am going to Nashville wed to pick up the sub which I got for 46 bucks online. I just want to minimize the chance's of me hearing the machine gun sounds at 4 in the morning and ahving to look for another sub or ship it back to JBL. I am thinking that if I leave it unpluged when I am not watching movies so that it will have a longer life. Any ideas or suggestions on what I should do?
