yeh, i need to buy a grill.. the box is all mdf and has .88 cubic feet. i bought it from an ebay seller named 'xk-xtremekustoms' for about $90 shipped. the pioneer subwoofer that i put in was supposed to be good for .7'-1.3', but it still sounded too small so i put in about 3/4lb of polyfil and now it sounds really clean.
