Amp help

[BTL15 1]

Hi my roomate has a sony stereo system and were looking to take the built-in amp and have it power a 12". When we took the cover off of his amp we saw what is shown in the picture attached. My question is which wires when cut need to be ran to the sub? I will put connectors on the wires so if he ever wants to wire it back up he can. Thanks for any help

No i didn't take out the sub, but i can tell you the sub has a on/off switch and a min-max knob so im guessing it has something to do with either of them.

red = positive

black = negative

So what are the other wires for? When i rerun the wires to the new sub i would like to mount the amp to the new box which would require me to cut all wires, and i just wanted to make sure none of them would be important.
