Racing door cards and speakers

[piranhamatt]

Hi all

I've been toying with having new doorcards and a bit bored of the standard ones.
I want to have speakers in there as well.
Has anyone got any examples of race door cards - front and back but with speakers in too?

is the only example I have come across but would like to see one with pull strap or a pocket etc.
Also example of the rear ones

Cheers
