Don`t know much about the rest of the stuff, but from what I`ve read, the ring & mountingarea that you can see on the outside of the Shaker subs are part of the speaker & not a seperate piece. Also, not sure, but I`ve read that the subs are some goofy 1.8 OHMs (or something like that), so what happens is that most folks just replace the regular speakers & leave the subs alone.
Having said all that, that is the exact setup I think I am going to get for my `13 GT. I don`t know if we have to get the `12 model year speaker rings, or if these speakers will just mount to the doors as is. The `13 GT has a "component" system (sort of)
Yeah I'll probably get the kit in the link I posted, It looks like a good deal for sure!
The JL audio stealthbox will probably sound good too,
I just wish someone around me had it so I could listen to it lol.
