Yea well I tried to do the most simple circuit possible it's easy to build on that. I assume it's wanted to go with the bass of any music/sound in which case should be able to add in a low-pass filter like so:
Which should filter out any unwanted high frequencies. But like I said especially if it's your first time doing something like this get like an old radio or something you can test with so you aren't worried about killing your main pc because of a short or some other problem in the wiring.
Edit: Should also be able to go from 'Sub' output from an audio card but I've never tried it and never actually measured the output of the black sub connection on 7.1 channel audio so not 100% sure it would work properly.
