radio comparison: sc901 vs hu850 (hu850 in p80 series?) P.S. Sig updated

[CIK7]

I have an sc901 in the Squall. I bought an hu850 from lkq about 4 months ago. Who here has had experience with both the sc901 (p80) AND hu850 (p2)? Which one sounds better? Would the hu850 be able to handle a 6.5" 2ohm DVC sub? Has ANYONE ever tried to put an SC faceplate on an HU radio or mod the hu850 to fit somehow? I see that the metal box section (holding radio contents) on both radios are the same size side-by-side. Who has some awesome info about my issue? If this doesnt work I will sell ithe hu850.
