I took this out from behind the double back seat. Not too impressed. There is no room for a box with a 10 behind the seat with the rear window motor, seat bolts, and other **** in the way. Anyone put subs in yet?

 

I've always built my own. I don't have a new truck but in the old ones I would cut away all the carpet and padding under the rear window and build an L shaped wedge for the driver side. I built a standard wedge that fits on the passenger side. If I remember right, on the old cab, the wedge was 3.5" deep at the top and 7.5" deep on bottom. I think passenger side is 18" wide and driver side L 20"? It's been a while since I messed with them.

It's not hard to figure out, you can do it.

 

Since we now share a cab (mostly) with the 150, I searched the 150 forums and some guys have replaced the sub in the plastic box with success. They upgraded the amp as well. Kicker also makes a complete replacement. Kicker SF150SC15 VSS? SubStage? Custom-fit powered subwoofer for select 2015-up Ford F-150 SuperCab or SuperCrew pickups at Crutchfield.com

I'm guessing these options will work with the SD and I too will be looking to upgrade after delivery.

 

Does anybody know how long it should take to break in the sub?
I know I home theatre it took awhile.
When I got my 2015 platinum is sucked!
but improved over time.

Is there room for a head unit upgrade?
like a kenwood DNX 893s?
sweet unit with the idata maestro link!

 

 

Didn't realize a Honda Civic that much rear leg room!

Just kidding!! Looks like a nicely crafted custom sub box.

 

did you change out the head unit unit?
