Now, I can read, and can tell one is supposed to be used WITH a factory amplified antenna, and one with a standard antenna. I have a 1988 Audi 90 with the standard two antennas. I have the front one hooked up to the "powered" antenna adapter I picked up from Circuit City. I just dont know where I am supposed to get power for the antenna adapter.
