Is the reverse polarity for corner loaded enclosure - the common setup?

I was running 2 Alpine 12" subs in a sealed enclosure aimed toward rear of car, no ski pass hole - much louder but more rattle.
No harm at all, the sub works the same either way. To clarify, this is to eliminate cancellations at/near the crossover frequency, and the main purpose is to help with the integration of the sub with the mid bass frequencies coming from under the seats and to "hide" the true location of the sub. It will NOT make the sub sound louder!

When you try this, also drop the crossover frequency - 100Hz is too high, try 80.
