18 re mx 4 cubic feet sealed or 12 in solo x sealed 3 cubic feet at 600 watts soon to be 1200 watts
If looking for SPL why are you looking at SEALED.
But of those two, the 18 is gonna move more air.
Why are you so bent on sealed. Build your own ported box for the RE. Get some plans from one of the box builders on here for cheap and go buy some wood and glue. The subs in your 2 choices are best in ported boxes. Especially the Solo X. Like pretty much everything Kicker makes but the Solo Classics. Don't do sealed man. You're going to be disappointed.im looking for bass to shake my windows and eveything , i hae the re mx but the box is gonna cost me 180 dollars or i can trade the sub for a solo x 12 in 3 cube sealed.
