SPL Difference in 1 15 vs 2 12s

The left side port should have helped the dash score. I'd guess the 12s would gain a hair more with that same port. But I'd doubt it would be audible. Yeah the wind is more then likely the center port.

Possibly, but all the loud trunk guys in my area (guys doing 55+) run center port...so I'm partially following their lead.

Wasn't necessarily looking for an audible gain going to the 12's, but it did give me the gain I expected (around 1db was what I was expecting).
