Hi streakn, thanks for the friend invite.
The haunt went fine. I put my cd and three others that I like on an iPod (wav format, not mp3). I ran signal outside to an amplifier and 4 speakers in the yard... sounded great. The wife had skeletons, tombstones, fog machine and skull torches in the yard. We had a lot of compliments.
I looked at the BooBox, but I'm still undecided. I'd like to have 8 speakers in my arsenal first. It's probably something I will try... triggered effects open up a lot of creative possibilities.
Thanks for the message. If you decide to pursue the sound system and have any questions just let me know. I have a buddy in Norco that my wife and I visit once in awhile - If I'm down that way I'll look ya up.
