check out the Maxxbass processor, do a google search on it, ive heard the theories behind it, and it makes sense, could work wonders. dunno the price tho

edit: oh, there would be some wiring behind it. as for the difficulty of the wiring, i dont know, but without a sub, i think this is your only way...

i meant aftermarket subwoofers, considering the stock subwoofer is barely noticable, and obviously inadequate for his needs
