When you mount the sub backwards with the magnet facing out it’s called inverted. The only advantage of inverting the sub is for looks. If you invert the sub you also need to reverse the phase +to- and -to+ so the sub will be in phase. You will also want to subtract the subs displacement from your enclosure volume. On the flame Q's I would not suggest you do a free air set up. I would suggest 1 cu/ft sealed or 3 cu/ft ported.
