A:AnswerPlease try connecting your speaker with another audio source (eg. another phone or computer) or try using a different aux cord and see if that makes a difference. We would like to work with you directly to help you with your issue so we can also check your amp and compare it with what's on our photos. Please submit a case request at https://www.jbl.com/support-contact.html and the Customer Service Team will be more than happy to assist you.
