Mounting tweeters higher up and on axis

I have a set of Polk SR6500 speakers. The general consensus is that the tweeters sound better on axis than off. I'm thinking of mounting them up into the cover that covers the door mirror mounting screws, the triangular cover. Has anyone done this or have any thoughts about it? I would angle them so the would be a more direct line of sight to the driver location.

 

check itylianstalion's dont think i spelled his name right but he has his mounted there

 

Try a couple configurations and see what you like. I'm running the same speaker and I think the angled coax mount is the best solution in our trucks, but other's have strong opinions to the contrary. Discussion:

I believe your tweeters are the ring radiator type. Yes, they will sound far better on axis (or close to it). I experimented with 3 very different sets of tweets in the stock locations and was never happy with it.

Once I put them in the pillars as seen below, the detail came in and the stage was of course raised significantly. So my vote, is yes. Move them to the sail panels or a-pillars cross firing (left tweet to passenger's left ear and right tweet to driver's right ear) and you'll hear a huge improvement.

Here's a tip for experimenting on the cheap. If you remove the sail panels (those black triangles), you'll notice a bolt pretty much dead center that I assume goes to the door mirrors. I removed the nut and replaced it with (don't know what it's called) something I found at Ace Hardware that was like a 1 inch deep metric nut. That allowed me to tighten it down, but still have something to thread into. I then used PVC pieces to rig my tweets into place temporarily. <$10 at Ace and you can determine if it's the right way to go for you. (basically, mimic Italian's tweet setup)

 

Great info, thanks guys!
