Factory Sub & Sub box

[hcfd63]

I am picking up a 2011 F-350 King Ranch this weekend, based on the others I have test driven, I know there is a factory sub behind the passenger side back seat. Didn't have a tape with me at the dealership, so looking for what the size of the factory sub, and are there any direct replacements for it that will use the factory sub box? Or are there any aftermarket boxes that will fit in the same space. I will say Ford did a pretty good job with the audio system on this, but as always it can be a little better.

Thanks for any feedback.

The factory sub is a little 8" with a crappy amp buit in the box. It is not feasible to replace the factory sub with an aftermarket sub because, in turn, you would have to change the amp to get enough power.

There are boxes that are made for these trucks. JL Audio makes one for the 13TW5 that mounts under the back seat, but you have to remove the storage compartment. Also, there are many pre-fab boxes out there like Subwoofer Box | Subwoofer Enclosures | Car Subwoofer Boxes and Truck Subwoofer Boxes at SuperCrewSound, SPL2K, etc.

Here are some pictures of my system in my 2008. The only mod I had to do was trim the back carpet and dynamat the back. In my new truck I am going to take out the seatbelt bracket and rellocate the rear slider motor and put two or 3 13TW5's behind the seat.

Thanks for the info TXStateAlum. I figured as much on the quality/power of the factory amp.

Great pictures by the way - really clean install.
