Logitech Z-560 .. left speaker louder than the right?

[LuDaCriS66]

All of a sudden today, my front right and rear left speaker seem to be much quieter than my front left and rear right speakers. I've checked the wiring and it seems to be just fine. I just put everything back together after moving back home from school. The balances under the Play Control panel under the Sounds and Audio Devices Properties are centered.
I'm using WinXP Prof SP1 and an Audigy 2..

any ideas?

/edit

Hmm, I had different gauge rating speaker wire for the rear speakers and the front speakers... so I replaced the speaker wire I got from radioshack with the ones that came with the speakers.. it worked for a couple of minutes but it's doing it again!
wtf.. the front right speaker gets quieter and quieter...

Reload your drivers. I had an almost same problem with another sound card (not Audigy 2), reloaded drivers and both speakers work fine again.
