Yup. I'm running a single JL W10 and it's perfect.

I'm planning to get the box made in the same area as this thread:

So, the biggest I can do is 1 or 2 8" subs.

Why not go with a zenclosure. At the end of the day, in a practical sense, I don't think you lose much space. Not sure how much a custom box will cost, but $130 for the zenclosure is hard to beat.

I did the silly extreme version, but they have more practical options:

I wanted to go stealth. I've always had a single 10" in my past cars though, so I'll consider zenclosures as well.

I can get a photo tomorrow, but I covered the whole thing in black speaker fabric And you cannot tell that the box is there; between the dark interior and the tinted windows, you'd have to know a priori that it is there. It also helps keep direct sunlight off the subs.

BOOM BABY!! I like

Why not take the prices you found to your buddy and see if he can match it... Always nice to at least give him the chance to make the sale.

This is a custom box i had made you do lose your spare tire :tup: but you cant even tell its there and i can still transport bags of cement ;)

It's hard for them to match ebay prices + I have to pay tax. But we were able to get the prices worked out. It's slightly more than what I can get online, but I'm getting factory warranty, a solid install, and I'm able to help my friend out. Definitely can't complain.
