See this same thread on 02-14-07 where I did basically this same thing as you, except a added a quarter-inch plug in a vent hole. So I plugged in the bass drum much as a guitarist plugs in his guitar. I just had to carry around a 3-foot section cable with custom-added ends when I went to gigs but other than that, it was very smooth and worked terrific.
