Took me a while to sell mine, so I gave up and sold it at a much lower price to the point where it was a steal.
bump for an excellent subwoofer enclosure! This is MUCH cheaper than getting a completely custom made one and its literally perfect fitment!

I believe it goes on the right side.
I don't think it will work if you have a sti TMIC spray bottle in the back.
I wanted to try selling together, this is a pretty crazy sub... based on the specs I have read... I actually have never ran this.... change of plans..

I was going to buy one off another guy on this site, ran into the problem with the intercooler spray bottle being in the way like you're saying. Thanks anyway, free bump.

Given this stuff is used but in good condition, it's probably worth around $3-400 to the right buyer. The sub is the best one Alpine makes and I would have gotten a pair of them had I not found Digital Designs first. That alone is worth $2-300.
