98 taco xtra cab sub box question
okay, kind of vague here i realize, but i have seen on ebay in the past (once) a rear firing sub box replacing the arm rest on a tacoma. havent been able to find a picture of one since, but i like the thinking. i think it held a 12" woofer too. i'm pissed i didnt save the picture of it! i have searched all i could on here for a decent hidden box design, or just something to get it out of the extended cab portion of my truck. i've been thinking of making one that fits on the floor too, but didnt see anyone on here with that setup. can i make a weird lookin box to extend under my seat to account for needed airspace? is there a rule of thumb about how close the air needs to be to the actual woofer? never made an oddly shaped box, but willing to try... any help appreciated!
