I'm not trying to argue either, just trying to not scare the guy off from trying something. $40 is still nothing. Are you talking about just an ordinary box or something custom? Because when I went to Tweeter and told them what I wanted done, they said just the enclosure would cost over 2 grand. I said forget that, went home and started building it myself. It was only like $200 in parts/supplies (not counting subs, amp, cap, etc.).
and comparing a custom system to changing your oil, come on man, that's apples and oranges lol. You wouldn't go to a meet saying, "hey guys, check out my oil that I just changed. It's so fresh and clean, and has a really nice viscosity."
But anyway, I hope the guy gets what he wants either way. Sometime this summer I hope to start my custom enclosure on the WJ. I'm fiberglassing it into the driver's side plastic panel in the cargo area that way i don't lose any space.
