Well now that I have my front stage done, time for the sub stage. I am looking for something that can get pretty loud when needed but still the ability to blend well into Jazz and Rock as well. I am doing a sealed enclosure in the corner of the trunk, but un-sure of size and sub still. Right now I am leaning towards a 15" Q but haven't heard a solid review on how the sub plays SQ-wise. Realisticly probally going to look to be running around 1.5kw. Also, I may consider entering IASCA SQ comps for some fun so that may come into play for choosing as well. Does anyone have any input or opinions?
