i have a 94 mercedes e320 wagon. just got the vehicle so i dont have much experience with it. so far ive tried a box with subs up and port up, as well as subs back and port back--these yielded the same score. trying to see if anyone has some experience they can help me out with. trying to do spl oriented only. not worried for daily. tuning peaks between 47-51 all around the same, i have a useable height of 15" (with surround on top of box), about 40" width, and every bit of 40" depth still leaving loading room. any help is appreciated. will be using 2 15s, and a single 10" aero. thanks in advance.
