  What is a LOUD box?? Well if you've ever started a conference you'll know that a lot of the times the conferees cannot hear you that well. Well this little BOX should clear up that problem. First thing you want to do is MAKE it, so get to that and come back when you're done. Ok, we now have the circut done, so heres what you'll do. First open up your phone and find the wires going to the mouth piece and cut them. Not connect the wires running from the microphone to the input line and the other wires running to the output line. There you have it, just turn it on, and ajust the volume control and the people at the other end will be able to really HEAR what you are saying.
