Anyone have a factory radio and speaker in thier 48-50 F-series truck? I need to know the size, length, width and depth. I have 3 different parts books and none list radio or speaker. I think it's a 5.5 x 7.5 size, Can anyone confirm this?

Thanks,

Barry

Probably a 6 x 9 which is a standard size speaker used for zillions of years going back to the forties..

I put a 6x9 in mine and it fit perfect.

Paul2748 is correct on the 6X9 speaker and most likely 4 Ohm. Check this web-site for new replacement speakers and radio updates.

He can update the old radios with solid state vibrators or replace the inards with late AM/FM technology.

PS: I think FoMoCo considered the speakers part of the radio accessory kit and due to that, you will likely not find a part number unless you find either an original speaker or a complete kit with the included parts list. Ford may have had accessory brochures or installation booklets as well but I haven't come across one yet for your model.

I've been in Ford parts for 30 years and Ford was famous for dropping things from the parts catalogs once they obsoleted a part. By 1960, 90% of the parts for the 49-51 cars and 48-52 trucks were gone from the system unless they fit later models.That's why the 48-56 truck catalogs everyone has are a joke. Most were printed in 1964, when they did a major revision in the parts system. You need the earlier ones from 48-53 or 48-54 to find what you need. Most of the radios were put in at the dealer after arrival there. The dealer made more $$ on dealer installed options. I have an accessory catalog, but it doesn't list basic part numbers to look them up. My net price book from july of 1950 shows 2 radio prices and 3 antennas, but no speaker prices. Somewhere there has to be some literature on this stuff. I haven't found anything yet. I've got a dresser full of parts dept literature and stuff, but nothing much on accessories.

Depends what radio source is to be connected to a speaker. If the headphone output or speaker out of a solid state radio is to be used then 4 to 8 ohm is the standard. The old tube jobs used speakers with a much higher nominal impedance, into hundreds of ohms rated, often with matching transformers on the back side of the speaker. That may be why old radios in otherwise good condition may sound distorted and rough is that using a low impedance speaker virtually shorts out the amp section and even destroys the amp eventually. Find an old radio guy to help sort out these matching issues. Often a tiny transformer can make things sound right. Good Luck: Fred A
