subthump dual 10" subs ported box
 

I bought this off a member on one of the sites (ls1tech, ls1 or ls2) about 6 years ago and never installed it due to my motor blowing up. Its been collecting dust ever since and I don't think I'll ever use it. I'm almost positive they are 10" subs but I can double check. It came with 2 Infinity subs in it (again not sure what model, but its a silvery white speaker face). I can get these details for you if needed when I get home.

From what I've seen on their site they dont offer the ported version anymore but the standard one goes for $225. Only issue is the vinyl has pulled back a bit around the one port (as you can see in the pic).

$200 or throw some trades out there.
