Well..here goes. I have an 88 hatch mustang. I have 2 shocker 12s. I have them in a makeshift box thats probably giving them each .6 ft each. For sealed they reccoment .9. Im a fan of spl, but dont have room for the ported box. What i want to knwo is what angle would be better to position the subs at to my hatch for optimum spl, if it matters much at all.
