Problem splicing sub into headphone jack

[BradSk88]

Okay, but I tried those ways and the bass is nowhere near as powerful as when I do it my way? Wouldn't the white(pink) act as ground?

no it is the other channel (red is right and pink is left). your way is summing the input together, which is why it is louder.
what kind of sound card do you have?
if it is center and sub you shouldn't do it as it is send 2 different signals which would explain your first problem. but if they both are sub it would be allright

Bringing this back from the dead.

Wire got ripped apart and now I can't find the way I'd put it together. I used the ways that EricB suggested and it works fine but after about 15 minutes the speakers start going 'whump whump whump' and getting louder and louder and I'm forced to turn off the speakers.

wtf?

that's a ground loop. your ground isn't hooked up

 

[BradSk88]

my ground is hooked up

(both and single )Ground from headphone jack and single ground from sub
Then either white or red from headphone jack to red of sub
and it's still doing this, it takes a while though.

wierd. usually that is a ground loop sound. do you have a picture?
