So ya i tried that...  http://i690.photobucket.com/albums/vv269/pookieh44/WP_20130529_0101_zps6f1a386c.jpg   And it just plays a constant rumble... nothing even close to the song, just blasts random tone. 

im trying to connect a home theatre sub into my pc... i already have a sub and 2 speakers, but i want to run another sub... so... 2 subs and 2 speakers.  I have a sound card, but idk how to make it work with another sub...  This is the sub ...
