Hello, I want to make my Harley Davidson radio headphones wireless. I bought a 12 volt Bluetooth transmitter and two sets of wireless earbud headphones. I thought I could just attached the leads from a 3.5mm cord directly to the speaker connections on my motorcycle but when I do the Bluetooth transmitter overheats and shuts down. Can you not do this? When I attach a JAM powered speaker to the jack it works just fine. Is there to much power coming down the speaker line to the transmitter? Thanks for your expertise. Keith
