well since no one else seems to want to post ill be kind and post....im dont know much about this but uhh... sounds like you are wanting a ported box? well ive never made a good one so i dont know what to tell you, but you say u want a daily listner for all types of music, wellll i would just say a simple sealed enclosure built to spec for the sub, it will also use less space leaving more room for other things considering this is a daily driver car n all
