Gale Force blaster UPDATE:
Yesterday I purchased two (2) Radio Shack part # 270-409 and a RCA Female plug. I connected the two 4 AA battery packs in series for a total of 1.5 volt X 8 giving me a total of 12 Volts. Then making sure the polarity was correct I attached the RCA plug. Connecting the two in series battery packs, created a extremely loud horn. My project was a total success. The battery life should be extended as all a 9 Volt battery is is 6- 1.5 volt AAAA cells with a MA rating of 500. The AA cells have a MA rating of 2000 each. ON my next ride I will test the horn in real life conditions. Below is a photo of the inside of a 9 Volt battery.
