hifonics bxi 1206d bass knob

[houseofpayner]

Hello I am wondering what bass knob i can buy that is compatable with the hifonics brutus bxi 1206d 1200w amp i have. i bought it off a friend and it did not come with the bass knob. i stupidly bought the hfr-3 bass knob that is compatable with the newer hifonics brutus 1200 amps but the cable connector is a 8 prong connector and my amp looks like a 6. I also found out they do not make the bxi 1206d amps anymore and cannot find anywhere the information about the bass knob that comes with it or where i can buy 1. somebody please cure my maddness with an answer to where o can buy 1!! please and thank you
