My sub woofer

ok this is getting me ver pissed off because im sitting here chillin, bout to watch RONIN and i noticed no boom from my baby sub

so my ? is

well aside from it not werking, how do i know if my sub woofer isnt working or how do i know if it blew is there a way of checking it???

well, if you can’t feel any vibration coming from the sub, then check your commections again. also make sure your amplifier (which i assume is configured correctly) is set to direct the bass to that speaker.
