What the ****

Ok so i hooked up 2 12"s in my friends mountaineer off a kenwood amp. He wanted to use the stock head unit so i told him he needed a LOC. After i had hooked everything up properly and turned it on i realized the subs weren't moving but there was a tiny amount of bass. Apparently he has a built in sub and amp. It does not use RCA's to attach to the head unit. How do i go about hooking up the kenwood to the head unit using the LOC? Do i need to use the stock subwoofer signal wires? He doesn't have a wiring diagram in the manual so i have no clue what wires to tap into. I used the rear speaker wires and the subs don't really pick anything up. I think there might be a built in HPF for the door speakers. Any help? This is driving me insane//content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif:verymad://content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif//content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

instead of wiring to the back speakers, tap into the wires coming from the amp..the thing i bought had rca inputs on it

That's what i thought, i just don't have a clue which wires go to the factory amp and i cant test them with a 9v battery like i did with the door speakers.
