Do they have the tweeter location too?
Under the grill guard, is there a mounting location?

 

Don't believe they have tweeters. Under the grill guard a mounting location for what?

 

I notice under the grill, where the factory speaker is, there is a tweeter location for some of the 04-05 f150s. Is this on all 04-05 f150s are just the ones with the audiophile sysytem?

I know the stx doesnt come with tweeters standard, but is there a location for them?

 

Just pry off the panel and see if you have the opening. I don't think any standard systems come with the tweeter (not sure on audiophile) but my screw had the holes for a tweeter behind the panel.
