There is another option that you do have, but it will require you to cut-off the connector of the FAST-BTAH that plugs into the Tube, which means that you will not be able to return the harness. You will also have to decide if you want to use the High Level or Low Level Inputs for the Tube first. If you decide to use the High Level Inputs, then you can do this;
Keep the Remote Turn-On wire, and your speaker connections at the headunit connected and disconnect the +12v (on the FAST-9999). Plug the FAST-9999 in the FAST-BTAH and then go to the end of the BTAH and cut the connector off of the harness. Find your Remote Turn-On Wire, and your 4 speaker wires and attach them to the harness at the BTA6200. You will then only have to run a seperate power cable and ground.
