WHAT COMPLICATED CRAP SHOTS......HAVE YOU TRIED APPLYING ONE SET OF
STEREO OUTPUT CABLES TO THE STEREO PORTION, THEN THE OTHER TWO TO THE
SUBWOOFER SECTION AS IS????
WHAT CAN POSSIBLY GO WRONG?
DON'T YOUR SPEAKERS HAVE A CROSSOVER NETWORK ALREADY ???
THEN ADDING ANY COMPONENTS TO THE MIX WILL ONLY DISTORT THE SIGNAL
COMING FROM THE SOUND CARDS AND YOU WILL HAVE TO RE-ATTENUATE IT ALL
OVER AGAIN BEFORE YOU ENERGIZE THE COMPLETED "REVAMPED" AUDIO SYSTEM
YOU PROPSE, NEEDLESSLY.
