Hi all.
I'm new to this board and a total noob at DIY audio. About a year ago I put together a cooler speaker to take to the beach with me and tried to use a bluetooth mp3 decoder (Here) for extra input options. The problem is that when the MP3 decoder is hooked to the amplifier (Here) I am getting a loud humming and thumping.
I built everything into the walls of the cooler so the interior could still hold ice and beer. I am running two 6X9 speakers on the side and one 8 inch subwoofer on the front. Playing it directly from the 3.5mm jack it sounds great. Lots of volume and plays for 5-6 hours on a charge. I would just like to have bluetooth capabilities.
Any help would be appreciated.

Have you tried other any other sources on the auxiliary input? And have you tried running the MP3 through the 3.5 jack? This may help rule out a bad mp3 board or possible problem with the aux input.
I am running a 3.5 mm jack off of the auxilary and plugging my phone directly with no problem. I connected the mp3 through the 3.5 jack and I still get the humming and the thumping. The thumping starts when I switch input channels on the mp3 board and keeps going like it's stuck in a loop.
