Attach an Amp to a Bluetooth Speaker

you have your positive and ground wire disconnected from the speaker

connect the positive and the ground wires to the audio cord

you plug the audio cord to the amp.

on the amp there are holes right behind the dc power plugin you want to solder those to the speaker.

you now have a bluetooth amp to make it louder and better bass

i used an old bluetooth speaker and just changed the speaker and added an amp instead of making a whole new speaker
