redoing my build for a 1999 ford ranger XLT that used to house two DD 1508s. got tired of the small cone area after hearing my first 160. my dimensions are 45 width, 25 height, 10 top depth, 15 bottom depth. im looking to work with around 2k-3k watts...dont know if a hair trick is possible with that power? I want to keep my box under the rear window so those are my max box dims. my question is, do I use these dimensions to make a box for 2-3 12's, 1-2 15's or 1 18? again, if a hair trick is impossible with my wattage and space, let me know on what you would recommend. ide rather be patient to get my hair trick, than to spend money hoping that it might be enough and reach failure. speaking of which, at about what decibel does a humans lungs struggle and hair starts to move; or can you reach high scores without moving air? im a noob here, thanks for the help.
