In the past I had a 2005 Tahoe that we installed a sub box for 2 10's under the middle seat. We've since sold that truck (still have the sub box) and are about to pick up a 2014 Yukon XL in a few weeks. I'm wanting to know if there is a similar box for the Yukon? All the searching I've been doing shows boxes for a 2013 crew cab available, but not much for Suburbans and Yukons. Since I don't have the vehicle yet, I can't check and see if the space under the seat is similar or not to the older Tahoe.
