Here is a quick shot for you to get the idea.

I will try to take a picture later today....the storage box was installed by the dealer, so I assume it is GM's.

I cut my box down with a gigsaw.... Followed the form of the sub box. It doesn't butt up to the sub box for fear of rattling. Just off by a hair.

I bought the whole upgrade kit. I bought it from http://www.shopgmcparts.com/electronics/2014-sierra-1500-crew-cab-audio-upgrade-kicker-powered-amp-and-subwoofer-kit/gm/19303117-p-1333.html

I got mine installed yesterday! It is perfect! I got it for $869. shipped. Hard to beat for the price.

I'd like to put a shorter antenna on....but what I have experienced is either the antenna is soft and bends from the wind when moving or the shorty antenna doesn't have the little wire wrap around it for wind noise and you can actually hear the wind in the cab. Suggestions on a shorty/stubby that won't suffer from those traits.

I had a muffler shop remove the stock muffler/flapper/resinator and install a 14" magnaflow yesterday. So far I like it.

Sorry not a great PIC, done with a cell phone and truck is dirty.

I will try to take a couple of shots tomorrow.

I had them put on yesterday, so I haven't had them all that long. I really like them!

That is exactly what I am running. I have a 2.25" level. I don't rub.
