Here you go. I tried it this weekend but I didnt have any luck with it. That is due to the 30 mph wind that we had all day long. I went to radio shack to pick up the amplifier and the speaker and the salesman told me it wouldnt work very well and that I should just use small portable speakers. So that is what I did. It had good volume and it didnt cost me a thing because I had everything I needed. Let me know if you have any luck with it
