Welcome to the Bazooka Forum Guzzball. The BTA8100 has a built in crossover and subsonic filter, so you do not need to use the sub option on your headunit. Not to mention, it most likely is a Low Level output on the headunit, which would mean that you would not be able to use your FAST harness. I am assuming that you have the FAST-9999 since you do have an aftermarket headunit. Here is how you should install the FAST-9999 with your headunit;
Blue/White: remote turn on
Left Front (-): White/Black
Left Front (+): White
Right Front (-): Gray/Black
Right Front (+): Gray
It is best to use the front speakers for your signal. If you do use your fader to adjust the sound, fading from the rear to front will cause a loss of signal. Using the front speakers will prevent this from happening. Please post back with anymore questions you may have.
