have a set of alpine 6x9 3ways sitting around, was wonding if i could wire the single four omh voice coils in series to achieve an 8omh load for my denon reciever rated 90watts per channel at 8 ohms.... would this be worth trying, i have my center, floor standing fronts and bookshelf rears but am missing rear center channel, do you thing the dual 6x9 would incoperate into my current system or waist of time??? thanx for any input

If the rear center channel is MONO or some composite audio mix, you can do as you mentioned. Hopefully, you can design an enclosure that has a shallow angled baffle panel for better dispersion characteristics. If the tweeter and mids are off center to the woofer cone, mount them so they face the outside edges of the box. This gives better mid/highs dispersion. Like this:

Two 6x9's wud be too much for a rear centre channel, usually this channel is dedicated to delicate surround sounds, a set of 4" coax wud be a better option here, you wud not want those minute sounds to over power other signals. Also that channel does not have lots of bass or even MB freq, they mostly have the MR and the Higher Freq.
A 7 ch surround system has the rear centre just for the sake of transition of the surround signals between the left and right surround channels. And it usually is like swez said a mono mix of the left and right surround channels.
Prefrably you should mount the 2 speakrs at a 45' angle to eachother facing outside. this will give u good dispersion. A shallow enclosure is what wud be required here.
Also mounting this enclosure at a height bit higher then the left and right surround speakers usually gives better sense of rear space. Ofcourse speaker placement definitely depends a lot on acoustics of the room u have ur system in.
The idea here is treating the rear centre channel just as much as it needs , cause it receives a very typical signal which is very minutely detailed.
