You didn't say how big the entertainment center is.
If you can get parts on the router table use it if not use the guide/fence on the router after you have it as one cabinet..
BUT I don't recommend using a rabbit bit for this job.
Rabbit bits will rip the plywood out, use Carb.bit ,one small cut (3/32") 1st.then one more. (you are cutting end grain and with the grain on the plywood in one cut and plywood likes to snap out (rip))

Flat on the table is the best way to control the cut. I assume the width of cut is the 1/2" measurement accross the 3/4" ply. thickness, right? And the 1/4" cut is the depth of cut into plywood.

Think about using the 3/8" rabbeting bit with a fence to make the cut and remember not all rabbeting bits are created equal. Find the bit with a shear angle on the flutes. (router bit flutes are on an angle) The larger the diameter of router bit the better the cut. You expose 1/4" of the bit though the fence and raise the depth cut on the bit to the full 1/2".

To prevent chip out you can build a chip break on the infeed side of the router fence. Check out this tip: http://www.routerforums.com/showthread.php?t=127



Good luck, any other questions?

Thanks. I did it flat on the router table, good side up, and got fine results.
