3rd Gen with JBL Subwoofer

Hey guys,

Just got my '17 Sport last week and was wondering if anyone tried swapping out the factory JBL Sub for a better one? I don't hate the entire system, but it does leave a lot to be desired. Crutchfield has a few 8" subs that it says will fit in the JBL system, but has anyone actually tried to mess with the box behind the seat?

 

I have done this in my '13 jbl. Purchased the Rockford Fosgate punch 8". Fit right in. I doubt Toyota changed specs so the sub is a 2 ohm dual voice coil. I ended up yanking it out and making my own 10" sub box. I still have the 8 inch I could sell you if you want.
