I haven't had an XD in a few years and likely won't again. So it's time to let go of this showpiece of an item and piece of EXD history.
What your looking at is a fully fitted custom fiberglass square Sub Enclosure with 12" Kicker L7. It was made on his XD1 and designed specifically for the L7 for that year.
Others who have installed custom evilcalvin enclosures: Bdiggy, Matrixloader, Snoozeone
Most pics are dead since the posts are 5 years old, but there is a great pic of it installed way at the end of the thread here.
It has been in an XD and an XD2 no problem, i didn't build my floor up like evilcalvin did, i just installed it right as is with no mods and it fit great!
All i used to secure it was strong velcro and it held great for the 2.5 years i ran with it before i traded in the car.
Sadly, whoever hosted the images from years back is gone, so all my threads are just dead links, that pic above is the only one of it installed i can find.
It weights about 55lbs with the sub, it's super awkward too. So i have No Idea how i'm going to box and ship it.
Pickup in Pittsburgh, PA or I can get shipping quotes. He shipped it to me so i know its doable. (if anyone has experience shipping heavy stuff pm me!)
Sub surround did lift on one corner, never cracked, never blew, no puncture or tear. Just the glue came up a bit, it was repaired and last plugged in it worked no issues.
I'll give it another test before sale to be certain.
Not looking to separate at this point so selling as the pair, box and sub.
Let's say $300 and see what happens. Might entertain offers.
I might be slow to respond, but i'll definitely be checking in.
