I totally agree. A custom made box would be much nicer. But it's not like everyone can just do make one themselves. And either way, a person who does it themselves isn't doing it to save $80 (as that kid said), they're doing since they can create a better product. Since parts and your time are going to just about equal out the price (if not surpass) the price of that of a JL box.
I honestly couldn't create something like that. I did get quotes for custom panel boxes, which were fairly high.
Either way, sorry to get off subject, slow day at work.
