Has anyone had any experience with this chip - http://www.parallax.com/detail.asp?product_id=30075
. It is priced good and looks liek something i would be interested in getting. But i have a few questions as to what sort of amp/speaker i would need. Can i hook it up to any little speaker i can find? Also can it power it or do i need to amplify it some how, and if so any suggestions.
