Well, that is where I'm having difficulty. I paid over $1500 for the box to be built, including the subs and the amp ran me around $350. Of course, there is no way I'd get what I really want out of it but I have had offers of $500 for the box (with subs) and around $200 for the amp. So far, I have no cash in hand so that's why I am listing them here (instead of craigslist).
