Radio head demensions?

[1LowToy]

I'm building a box for behind the seat. Space is real tight and I need the demensions of a radio head i.e. sony JVC so on do I can continue.

I'd go buy a new radio head but I'm still married

Got this from wikipedia:

Head units generally come in either single DIN (180 x 50 mm panel) or double DIN (180 x 100 mm panel) size. The depth is not standardized; as a result, some cars such as the Opel Manta have the correct sized front aperture but will accommodate few DIN sized radios other than the original due to the shallow depth; this despite the vehicle being manufactured as late as 1988. The US standard for a DIN radio is 2" x 7" and the Double DIN sized radio is a 4" x 7". Some radios in Japanese Kei cars do not conform to the DIN standard however.
