When I disabled the ANC using FORScan, it totally stopped the brum in my new subwoofer, which is only connected to my factory rear panel speakers (using them as High Level Inputs to my sub). This is true whether I'm in Normal mode or Sport mode. I disabled ANC by changing:
727-01-01 xxxx xXxx xxxx
Change that value at X... it is probably currently an A or 2 (or whatever value). Subtract 2 from it... If it is an A make it a 8, if it is an 2 make it a 0, etc...
