00 acura tl bose sub

I installed a radio in a 00 tl and it didn't retain the factory sub. I didn't have enough time to test the second plug that plugged in the back of the radio. But i was thinking maybe that was the plug that gives the signal to the sub. I was just wondering if anyone has intergated the subwoofer with a aftermarket deck because they don't have a 2 plug harness for an acura/honda?

this is all the info i have for a 00 tl . if i remember correctly the amp is behind the back seat .you will have to remove it to find out
