looked around for an answer on what size i should make a sealed box for 2 12" inch hcs but have not found anything specific. I have very limited room in my trunk so going with a ported box has been ruled out. I have right around 3.5 cubes to work with (i know its not much) but with two 2 12" hc's what would the recommended size be to achieve the best sq while be able to get semi loud. Remember i only have a little over 3 cubes of space. Thanks for the help.
