Having a Yam RXV1 that has sub outs for a main sub and 2 output for rear subs, I keep thinking of adding the rear subs to see how they'd sound. Before I go to this expense, some of yall tell of your configs if you use rear subs. Right now, I have a 20-39PC SVS doing the main sub work and I can't imagine rears making it any better. I would imagine the rears would have to be fairly strong to show up... What do yall think? ------------------ "I am part of all that I have met, yet all experience is an arch wherethru gleams that untraveled world whose margin fades forever and forever...."
