On monday I got my car back after having some door pods installed for my SPX-177A in which I have both the Tweeter and Woofer mounted in the pod. I couldn't mount the tweeter in the kicks because 1) there was a fuse box which would require to much work to move and 2) I was using the other kick to hide things behind.
Anyway now I find my sound stage has droped down abit probally around gear stick height. Before with the Tweeter in the part behind the side mirrors (forgot the name for it) my sound stage was higher but I was getting reflections from the glass hence why I got door pods.
Now what Im asking is how can I now bring the sound stage up higher I know I can perhaps angle the tweeters up more slightly to rasie it but that would require more work to be done to the pods which I don't want. Would I be better off installing some abmient tweets?
Also ideally where should I aim for my sound stage to be? Should it be roungly on top of the dash height?

Are you talking about stage height for CAASQ or just SQ in general. In CAASQ height should be in line with the top of the dash/middle of the windscreen. In general SQ.... if youi like it then why bother. Also you don't want to change the angle on the tweets BUT are preared to pay for ambient tweets. I would fix the problem and not bandaid it.
Hope this helps.

Honestly, to improve the stage height, improved angling of the woofer/midrange and tweeter is required.
Unfortunately, ambient tweeters will cost even more and still require stuffing around to angle them and build pods - even then, it won't improve things that much, unless the midrange and tweeter are angled as well as the could be in the first place.

You mentioned how you had reflections from the windscreen when the tweeters were mounted higher up on the sail on top of the door.
The trick is to know how to use these reflections to your advantage.
Yes it can be a very "live" part of the car and can tend to accentuate the audio band the tweeters reproduce. This can sometimes be combatted by actually facing the tweeters into the windscreen away from you so that you are then more off axis. This may tend to naturally role off the top end a tad making it a little more pleasant to listen to.
The sound will tend to bounce off the area the tweeters are aimed at therefore making it seem as it the sound is coming from slightly higher up. This will then raise your sound stage as well.
Voila...sweet sound and good windscreen/bonnet top stage height all in one.
Don't be scared to reverse what you have done with adding the pods. Sure it cost you some coin but you abviously still have concerns although they're in relation to another area now. I dare you to go back and try this approach.
I used this method in my IASCA competition Liberty when I had it. My mothers car got the same treatment for her Infinity splits in her Alfa Romeo and a few of my customers' cars now use this as well. All get great results.

Thanks for the advice seems that an ambient would be just as much trouble and might not slove it, I can live with it and I'm still happy with the results but it could be better.
What I really need to is get my hands onto a good reference disk so I can really pin point the where my sound stage is because atm with just normal CD's its varying abit also.
Thanks guys.

Chaging CDs won't change your stage height one iota. Put simply; if you place your speakers low your sound stage will be low - and vice versa. Yes, placing tweeters up high can create reflection problems but this is the trade off for increased stage height. I suggest playing around with different firing arrangements. I have found high mounted tweeters to be fine in most cars with a crossfiring arrangement that sees the aiming towards the rearview mirror. This way they are firing in a manner that will cause minimal glass reflections while not angling too far back and causing a side bias for each listener.

Mick, you can always take it back to Northfield and they can help you fine tune the speakers. Also the soundstage seems to be lower because you are so used to having the tweeters up on the sails. Give it time for your ears to adjust. And also you might be actually concentrating to hard in trying to spot the speakers with your ears.
Just somethings that i have learnt.
