Unless I'm missing something, it would seem pretty easy to just drill a
few extra holes in that Leviton plate and screw in the requisite number
of single binding posts.
Even Rat Shack carries several styles, here's one:

And, I'll second and third those folks who've already told you that
"common ("negative side") isn't very common" these days as far as audio
amplifier outputs go. Don't try using them for more than one amplifier
output at the same time.
HTH,

The ideal solution would be to replace the single gang box, with a 4" square
deep box, or simply a 2 gang telecom mud ring. You don't actually need a
box for speaker/telecom/data/coax. You can get rings that can be cut-in
and mounted directly to the sheetrock.
You are going to run into problems with fitting all those wires in the box,
and putting a plate on, especially the coax.
You could also get a 2 gang wiremold extention box, and mount that over the
existing box, and use a 2 gang plate, which would give you a maximum of
12 spaces for the quickport modules. It looks like you will need 10 spaces
total, 8 speaker (4 pairs), 1 data, 1 coax. The box will stick out from the
wall about 2 inches.
If I were doing this, I would bring the speaker lines in to one 2 gang mudring,
network/telephone into another, and coax into a third. I would run a minimum
of 2 net, 2 tel, and 2 coax, and I might even go as far as 4-6 coax
(antenna, cable, 2 sat, in-house distribution, spare), run to a central
location for patching. Think dual-tuner satellite receivers. Putting 1-1/2"
or 2" conduit in to allow pulling new cables back to your patch area is a
good thing.

As previously mentioned, not a good idea. A lot of amplifiers today are
push-pull design, with neither side being grounded. Grounding either side
can kill the amplifier.

That sounds doable, but one side would require an eight port module and
the other side would require the snap in connectors for coax and
ethernet. I never saw any double gang wall plates like that, so I
would be back to square one?

You mentioned Leviton, so I assumed you were looking at the Quickport plates
and modules. They have plates with 12 spaces that you could use. You will end
up with 6 spaces on each side.
I would use the lower 4 spaces on each side for speaker, and the upper 2 spaces
for network and coax, with blanks in the unused holes. something like this:
NETWORK BLANK COAX BLANK
FRONT-LEFT+ FRONT-LEFT- FRONT-RIGHT+ FRONT-RIGHT-
REAR-LEFT+ REAR-LEFT- REAR-RIGHT+ REAR-RIGHT-

I think the 12 port is what I need to git'er done. I'm going to
carefully remove the single gang box and install a double gang old work
box.
Thanks!
