Wasn't sure where to put this because there are speakers, a sub, an amp, and a PC involved. I opted for here because my question is basically about a subwoofer. Please move this if I erred. I have a PC setup like so: 2 JBL S38IIs 1 Harman Kardon PA2000 amp 1 PC with SoundBlaster Audigy 2 Pics here I have a 1/8" stereo to RCA splitter similar to this from the sound card speaker out to the PA2000 with interconnects. Then normal speaker wire from the amp to the JBLs. What I would like to do is throw a powered SVS into the mix, but I'm not sure how I can do that. Do I have to pass the signal from the sound card to the subwoofer and then to the PA2000? Do I even need the PA2000 if I use the amp on the SVS for the JBLs? Thanks for the help.
