Need Help setting up 4.2 speaker setup on Computer

[NitroxideOG]

I have 2 Klipsch Heritage 2.1 systems and a Sound Blaster Z sound card. I want both 2.1 systems to get the full power but it seems like the rear channel jack is not giving as much juice as the front channel jack is (maybe b/c it's meant to power a 2.1 and rear up to 2.0?), the rear 2.1 system is much quieter and the sub does not hit nearly as hard.

My question is how to resolve the issue and get full power to both systems? Is there a soundcard that would support 4.2?

Looking for any guidance, thanks!

Did you install the soundblaster software? There's a control panel in there where you can play with the volume of individual speakers. Having said that I don't think any soundcard is made with X.2 setups in mind and rear channel is always going to be less intense/loud than front channel just because of the way people's hearing works. There may be a way to do "dual 2.1" where both setups get full power as stereo setups but then you wouldn't get surround sound. What you're trying to do is very outside the box both in terms of combining 2 speaker kits and using 2 subs. Personally I'd shoot a detailed clearly worded email to creative labs and see what they suggest.
