New radio with factory look

[Stepper86]

Hi guys.
Im quite new to the site (been lurking for a while)

So I want to put in a new radio, but I want one that will fit in to the original dash. Had a look at RetroSound, but they seem to be a bit limited if you want to expand the speaker system. Im not going to build any "monster, wake up the neighbourhood" system. But would like to add a bit more punch than you would get out of the original "4 in the corners" system:-)

Anyone here that has some experience with these "retro/factory look" radios, and could give me some pointers?
