Anyone know a place in DFW to install a subwoofer?

I've decided to forego the hifi package and instead just buy a subwoofer to increase the bass. Any recommendations on who can do the work correctly?

Love to know this too. Still waiting on my CPO but I know a sub is something I'll want sometime. Looking at some of the aftermarket options and install videos I'm not quite sure I'm ready to dive into modding a tesla myself.
