i have a pioneer DEH-P7700MP cd receiver and im hooking up a 4 channel highs amp and im confused on the rear output settings non-fading output,subwoofer output i got my subs hooked up on the S/W output and i have 2 other outputs a front and rear output but when i get into the settings of the deck shows like (REAR SP:FULL) (REAR SP:S/W)???? IM LOST WITH THIS DOES THIS EFFECT MY HIGHS OR JUST MY SUBS??? INFO PLEASE

ALSO THE DECK HAS 3 OUTPUTS IN THE BACK REAR OUTPUT, FRONT OUTPUT, AND S/W OUTPUT I GOT MY SUBS ON THE S/W DO I HAVE TO RUN 2 OTHER SETS OF RCAS FOR THE FRONT AND REAR AND HOOK THEM UP TO MY AMP?? THE AMP HAS INPUTS FOR FRONT AND REAR THANKS FOR THE HELP
