lol if all else fails just give it a quick pop with 120 out of a wall socket using a small gauge wire to the battery terminals it will be dead real quick.. just dont zap yourself.. we use this all the time to get subwoofers replaced from stubborn companies that think our customers are not worth their time.. wanna see the max xmax of your woofer lol... (please be cautious ive been working with electronics for 15 years this is and should be a final resort if all else fails)
