subs wired wrong?

hello everyone i had a friend of mine install my system awhile ago and i got 2 Audiobahn AW1200Q dual voice coils,700 watts rms 1400 max, hooked up 2 a Power Acoustik LT1920/2. im not shure but i think they are WIRED WRONG AND I WANTED 2 KNOW IF THEY WOULD STILL EVEN WORK. i unscrewed them 2 look at them. apon looking at them they are wired like this, on the left side up and down are both negatives and on the right side of THE SAME SUBWOOFER the top is a negative and the bottom is a positive! and it is the exact opposite on the other subwoofer. so will some one please tell me how to wire these or TELL ME IF THEY WOULD STILL EVEN WORK because when the bass hits at mid to high volumes it sounds like its pushing out a lot of air and sounds like its hissing. btw i got a 95 civic and the subs are faceing the back end of my trunk bc i cant stand the hissing sound and it hits harder. and i want to wire them so they can get the most power . THANK U 2 NEONE IN ADVANCEi came,i saw, i forgot everything
