So, Great Success!!

The 6 in. speakers turned up and fitted no problems in the back (Fusion PF-FR6030, in case anyone wants to look them up for size reference). In the rear of my 110, the factory speakers are in a stepped/recessed hole in the rear trim. All I had to do was dremel out the factory hole, basically just removing the inner recessed step, and they sat in well. Four new screw-holes, plug in the wires, and we're done - no fouling/interference issues anywhere. They look fairly standard, but are pumping out a much better sound. I will admit they weren't a huge change on the 5.25 Fusions I had in there previously but there's some improve, and TBH with the price they were it was well worth a try.

Hope that helps someone, at some point.
