I have that exact vibe unit in my transit, I have found I am happy with the sound now and haven't been in a rush to amp the oem speakers or indeed upgrade them.
So for the vibe, it allows high level and low level input... high level being already amped and low being the rca pre amped inputs. So you can choose.... the oem Ford system has no pre outs (rca's) so yes just chop into the back of the head unit outputs, and connect via the high level speaker wire supplied with the vibe. Power I got from the battery but I would use the f21 fuse if I did it again.
As for your amp, if it allows for high level input (which most do) then you can use that too. So it's your choice really. I really like the vibe unit and I paid 160 for it and thought is was decent value..... so at that price I would grab it. The only issue with it is the lack of remote, but as mine is under the middle seat it's easy to adjust.... I may look to see if it has a remote option.
