I don't think that 150 will be as difficult to achieve as some people are saying. I ended up sealing my box because it wasn't large enough to be ported. (turns out it is like 1.5 cubes smaller than originally thought) Also I was having some terrible cancellation issues but thats another issue. But now I'm 2 SX 15s sealed with 2500 watts firing to the rear in a Grand Prix. If I had to guess just off of listening to it, i'd say im hitting mid 140s with music. Once I glass my trunk and forward fire them with a huge port (still sorta working with Pete Kuliki on port dimension. he makes me feel stupid sometimes though.) i expect to be hitting into the 150s with music in a d/d.
