I know it’s a week later but I’ll chime in too. The Punch 300-10T I think is a little different dimensions than the -10 or -12” ones. I think it’s less “tall” so it fits under seat better. Just measure for yourself.
I have the same model for a year now and it’s perfect. While it won’t rattle the neighbors, it’s more than enough for the hip hop/rap/electronic/dubstep I enjoy. I also replaced the door and dash speakers. I hooked up the subwoofer with wire taps on the speaker wire bundle under the steering wheel before it goes into the front door.
