anybody have any experience with sub forward port forward on their enclosures?I got a blowthru in my truck and a AQ 2.5 15 in transit,should be here by friday.(a)I think sub forward firing directly into the cab,w/the port side firing will give better sq,but i dont want to lose SPL.(b)sub and port firing forward into the cab should give better spl.but not sure,any suggestions?option 'b will be easier to build.
