    Default woofer blowing fuses

    blowing fuses

    I have a polk sub woofer madol LR106476 that have worked fine for 4 years and all of a sudden stopped working,i opened it up today, and found a blown fuse,i replaced the fuse with a 1.5 amp i cant read the amp size for sure but looks like a 1.5. anyway with the new fuse it blows as soon as i plug it in,the speaker makes a humming noise and the fuse blew and only did it once two more fuses and it blows right away. any ideas?

    Hello Louis,
    Thanks for posting on Polk's forum. In all likelihood there is a problem with the subwoofer's amplifier and it will have to be repaired. It would be best to contact Polk's customer service department at 1-800-377-7655 or send them an email at They'll help you out.
    Regards, Ken
