I've seen the PAC adapter that provides low voltage RCA outputs for a sub but I'm curious if I can just splice into the factory sub outputs on the 8 wire plug and run that source to an amp? Has anyone tried splicing into the sub outs on the 8 pin connector and running that to a mono sub amp? If they are already filtered for bas and low voltage they would seem to be a perfect source for a sub amp.

Any advice would be appreciated.

if you're using the outputs from the stock radio, they're already low-pass filtered. Problem is that they're differential outputs (signal on both the (+) and (-) wires) so you can't just run those to a single-ended (signal on (+) with (-) tied to ground) RCA input on an aftermarket amp. You'll need an isolation/matching transformer for each input.

OK that explains why no one does it. So if I am keeping the factory radio the PAC adapter isolates what I need? All I want to do is pout a small sub in the trunk wih an amp. The amp I have has high inputs on it, I could pull high signals off the rears too.

which PAC adapter?

AOEM-FRD24 but it looks like it just converts high voltage outs to low voltage outs. I read the install docs and it doesn't really say.

the adaptor you looking for is called a line out converter, or loc. You may need one of these depending on how high of a signal it really is as some of the ford amplified systems use a really high voltage preamp input.

A lot of amps already have the LOC included in a small area normally labeled "high level input" and that might work for you. The only warning I give about using an LOC is that you really want to tap the signal for it as close to the deck/source as possible. If you don't any noise that the wire picks up along it route will then get fed into your amp and amplify the noise as much as the music.
