Hi,I'm having a really hard time choosing a new sub. I think I've narrowed it down to these two, the new orion hcca 15.2, or the fully loaded 15" Fi BTL. It will be a daily setup in a 95' nissan hardbody. I will be running it on an orion 2500D in a 4 cubic foot ported enclosure. I would also occasionaly like to see some fairly good mic numbers. Please be honest as to which is the better sub for my application, thanks.
