Why my sub only work with just one pair of input

I have a problem with my DS7200SW sub.
when I try to hook up all five input wire there is only one pair of negative and positive input work.
I try to hook up all the negative and for the positive wire I just put them together to the positive input that work. That will give me all the sound for five speaker.
I wonder why the redt of four positive input not workingxdjytbmafrga.jpg

    While the problem could be with the amplifier inside the sub it could also be that the problem is inside the preamp/processor. That is an old unit and no parts are available. I'm afraid it's time for you to shop for some new gear. You can use the speakers, but you'll need a new AVR, sub and source player.
