New stereo head unit help please: A single or double DIN size? Im changing out my 130 head unit in my '14- my current project. I'm not asking for a particular recommendation on the brand, model or whatever. I'm looking for which size to use. Does the single din type look small in the dash? They both will fit in the dash, with the double din requiring some mods as crutchfield says. I posted this a while back and didn't get any useful responses, so I'm hoping to here. I need to narrow the selection to one or the other soon, as that cuts down many of the units. Thanks
