How do I tune this? Answered

I bought a passive subwoofer crossover the other day in Toronto at some crazy combination Home Hardware/Chinese ran semiconductor supply shop. It was simply bought as a pcb in a bag for $18, which I thought was a good deal for that much so I picked it up. It has a large inductor coil and a 188uF 50V capacitor mounted on it, along with a positive and negative terminal soldered on for input/output mono speaker connections. I did hook it up to try in line with my sony stereo and turned the default button on my EQ on to restore the original signal and it worked pretty good to block out most of the signals like I was looking for it to do. However even with the boost on my EQ at 30 and 60 hz, it's not coming through to my sub even like before I hooked the crossover up. I was wondering if that's because of the capacitor or not? The little peice of paper that came with it said it was a 120 hz passive crossover and that it was workable with 4 or 8 ohms. I'll post pics tommorow when I wake up as it is lateeeee. I appreciate if anyone can help me as I don't wanna take the capacitor off there to find out that it wasn't worth it.
