I'm going to replace my factory speakers with components .I was wondering where the best place is to place the tweeters and the crossovers in 2002 f350.

 

If your doors are anything like my 08, I put them in the triangular sail panels that hide the side mirror bolts in the upper front corner of the doors. Gives an uninterrupted stage for the highs. I did have to mount the crossover in the door itself.

 

I mounted my Infinity Reference crossovers and tweeters in the doors and I get plenty of sound from the tweeters!
