I've had this subwoofer for about 2 years now, and it has served me well. It gives me the perfect amount of bass with my sound system. Recently, however, I've began to experience a problem with it. When I press the power button, I wait for about 4-5 seconds, and then there is a click noise (the usual noise it makes when it turns on), and then there is a low pop or boom sound, and then it makes the click noise again. It is almost as if it is kicking itself out and the overload protection is initiating and turning the speaker back off. I opened up the back of it a minute ago and sprayed some air on it because it was extremely dusty inside, and tried it again, and it turned on, but when I tried to turn up music at all it once again kicked out. I'm pretty upset as my music sounds empty without the bass to go along with it. Any tips/advice/help would be great!
