Step 2: Connect your XLR cable to your speaker

now you need to connect your XLR cable to the speaker. this part is easy and soldering is optional.
ok so depending on what speaker your using you may or may not need to take the speaker apart. 

(instructions for a speaker with wire clips on the back)
1: just connect the positive and negative wire to the back of the speaker

(instructions for speaker without wire clips)
1: if your speaker has a wire coming out the back then you can just cut the wire and connect it to the XLR and your done.
2: if your speaker does not have a wire coming out of it then you need to open your speaker. there should only be a few screws you need to undo. 
3: once your speaker is open you should see the back of the ACTUAL speaker. you will see a positive and negative connector on the speaker. just connect the XLR to that.

and thats it. its that easy. you can now talk into your speaker and it will be a microphone. simple!
