Connecting headphone jack to standard speaker?
I took a speaker out of an old CD player and I have an old headphone jack with the wire that I want to connect to it. I have done this before but I have one problem: the sound. When I plug it into my Ipod it is only as loud as the headphones were. Would a transistor amplify the sound and make it louder? If so how do I do that with only two wires? I am trying to figure out how to make it louder. Thanks.
