Just make sure you tape all around and drill away. I cant say it will be comfortable, I did mine with the doors off. As far as size its 5.5", I will say that 51/4" is what I have in mine because well.... they were free. And if you are willing to cut and keep your window up there enough room in these doors for a 10" Sub if you really wanted.
Something else I did today was drill the holes for the door speakers. This cab was an AM radio cab so it didn't come with door speakers. Consequently the door pillars weren't drilled for the wires. This was a simple, quick job. Took about five minutes to do both of them. The pillar is already marked, it has a dimple stamped where the hole needs to go. 3/4" hole saw and done.
So the pillars are 3/4" and the doors are 1" or 1 1/8"?
My daughter and I have been wanting to put a little more sound in our 1977 F100. The previous owner had upgraded from the stock AM stereo and single in dash speaker to a Kraco stereo with 2 CB speakers mounted under the dash. Needless to say, it was in need of an upgrade. We looked at several of the updated 2 **** stereos, but the cost of them versus a newer DIN style radio and the features offered, we settled on a DIN radio. We didn't want to cut up too much of the truck, but knew we would have to modify the bezel. Ours is cracked and I would really like to replace it if I can find one in better shape. We decided that we would go with some 6x9 in some boxes behind the seat and some door speakers and a decent head unit. I was able to find some Line-X coated 6x9 boxes for $39.99 a pair and grabbed those.
We got on the net and started looking for speakers and settled on some Rockford Fosgate P1692 speakers. Crutchfield had a sale on Rockford Fosgate speakers were you get the second set half off. I searched and found out that 5.25 speakers would fit in the doors so we found some Rockford Fosgate P152 (they were on sale for $99.99, normally $119.99 and we got them for half of that, $49.99). Looking around for stereos, I have Alpine in most of my other vehicles, so we got an Alpine CDE_143BT. Its a great stereo and was only $129.99. I also grabbed some XTC Speaker baffles to protect them in the doors.
I removed the door panels and test fit the speakers in the doors. These fit like they were made for the doors. Two of the mounting holes lined up and I drilled out the other 2.
My truck did not have ANY wiring in the doors, nor any grommets for wiring, so I had to get creative. Using a step bit, I drilled the doors from the inside until a grommet would snap in. When it came to drilling for the cab side, I had to scratch my head. I do not have a right angle drill, but needed one. Not wanting to go out and spend $200+ on a drill, I grabbed my right angle die grinder. I grabbed a 1/4" drill bit, cut it off so that it would fit in the grinder and snugged it up. This worked like a charm.
I plan on putting power door locks in the next time I have the door panels off, so I went ahead ran all of the wires in some fire braid, popped in the grommets and fished the wire with some TIG wire into the dash.
Here is a picture of the speaker mounted and ready for the door panel to go back on.
I don't have any pictures of the rear speaker boxes, but they fit great and allow the seat all the way back. I wired up a new harness that runs all the way to the hot side of the solenoid (way less corrosion than at the battery), as well as a new power wire for the cigarette lighter/power point. The switched accessory and illumination were found in the dash and all wired up. After modifying the dash and bezel, the Alpine slipped right in. This stereo has a microphone that we mounted on the visor for phone calls and allows this via Bluetooth. The sound is great and my daughter is happy. She did say that she is excited about thee new stereo in the truck, but was quick to point out that she now needs one in her Escape.
Nice write up and photos! I'm in the process of doing a similar project right now. There's so much mixed info regarding proper speaker size out on the net, it's making speaker selection challenging for me. I'd like to not drill extra holes if possible. But anyway, as far as diameter goes, 5 and 1/4 is the best fit in the stock hole?

The ones I used were Rockford Fosgate Punch P152 which are 5 1/4" speakers and dropped right in. I think even some of the holes lined up and I only had to drill one.
I put 5 1/4" Pioneers in, they were a little small and I think only 2 holes lined up - they aren't as nice of a matchup as some. I had a set of 6.5"s laying around, and they were too big to fit down in the hole without some modding, so I stayed smaller (have 6x9's behind the seat). If it was a 2 speaker, or if I was going to put some small ones in the B-pillar, 6.5" is very do-able, but not a bolt-in.
I've been trying to find the specs on the speakers used in the doors of the F series. The Ford truck parts catalog says they were 5-1/4" round but does not provide the impedance rating of the speakers. Can anyone help provide this information? They usually work better when they are "matched" to the radio. Thanks.
Of all the stupid things I have notes on, I've never written down the screw spacings or the door hole diameter when I had one apart - next time..... Good to know that JVC makes one that fits, are they advertised as a true 6"? I think the ones I had here were Sony's, called 6.5" on the box, and were a little big on the inner ring to lay down nice.
