I have adquired this sub box without the 8 pin cable and I found in archive section that the acoustimass9 has a serial data wire and I want to no were do I connect this wire to use without a receiver.
Yeah. I'd like to know this also. Anybody? I have the acoustimass 25 (II) with 13pin cable. I'd like to hook-up directly to my media center PC. I can provide the audio signal to the RCA but not sure how to provide the voltage to trigger the power to turn the powered sub on.
