Anyone know how many ohms the stock 04 ford f150 door speakers are?

 

should be 4 ohms per speaker, sometimes car manufacturers used 6 ohms(no idea why) but since its a 2004, and these days the speakers and stereos are made by sony, pioneer and the like(just have a ford logo on them) then i would say your chances are pretty good (99.75%) that they're 4 ohms a piece.
why do you ask? i may have some advice for you.

 

they will shake the mirrors or at least on my

 

I will concur with Matt, yea they are 4 ohm

 

Becaus Im getting some 3 way speaker and to sound good with the stock radio they need to be the same ohms as the stocks. Also to sound good they need to be greater than 90DB and have a minimum watt rating of 2-5

 

bbbbbbbbumpin it to the top of this forum to get info fom that guy

 

good idea replacing the stock speakers. usually the stock stereo is pretty good if using upgraded speakers. make sure that the depth(mounting surface to bottom of magnet) is the same or less than the stock speakers. its very annoying to put in your new speakers and have the magnet stick to the inside of the door panel. (good ole' fords are pretty good about having enough depth, but its worth checking.)
