Music player from old portable stero?
I recently obtained an old stero with the capability of using batteries or an electrical cord on the back to play music,listen to the radio,and the likes. The case is busted up and stuff. Is there a way to repurpose this device? Id like to take out the speakers and the headphone jack. Forget the cd player and radio and all. Id like to take out just the speakers and jack and make portable speakers with a jack for an mp3 player. Im not much of an expert on this. Do i need to keep the battieres/electrical cord? or can i do away with it. How long would it last running off a regular mp3 player?
