Hey, I found some old speakers from a broken lap top and wanted to turn them into speakers that connect to my iPod. I need a amp though. It needs to run off of 7 DCV - 12 DCV from a battery pack, and the input comes from the iPod headphone jack. I tried a few things, like using a nPn transistor and a mosFet, but iI could not figure it out. Any help? Diagrams and explantion would be best for me. Thanks.
