NO

- Maybe I have not made myself very clear sorry.
But before continuing it should be noted that I am quoting from my own personal experience of owning both a Gen 1 Exclusive model and a Gen 2 Trophy model.
As both of these models, have the upgraded stereo systems with more speakers !.
Therefore I am not 100% sure if the Gen 1 Excite or Gen 2 SE models have these extra speakers in these locations.
The grills maybe there, but maybe do not house any speakers ?.
It makes no sense to produce two different trim covers for each model to me, they may just omit installing the speaker / tweeter or maybe it is fitted on both models ?.
Anyway we digress as normal !.
So okay, you are now sat in the drivers seat, look slightly to your right and you will see a white cover over the "A" post, located between the front windscreen and the drivers door.
This white interior trim, starts at the point where it joins the roof lining and ends at the bottom where it joins the black crash pad of the dash panel.
Hiding behind these white trim panels are air bags !.
Towards the very bottom of this white trim ( where in contacts the dash pad ) you should see an oblong ( ish ) shaped white panel, with tiny holes produced into it's face.
These oblong shaped inserts are speaker grills, they houses a pretty small ( less than 2" if I remember correctly ) a radio speaker / tweeter.
It has a matching one, on the passengers side also in the same location.
Less than a couple of inches away, from the bottom of this white trim, there is much larger slotted vent holes ( three or four I think ) produced in the black top crash rail of the dash panel.
These are heater vents that you are speaking about I think ?.
I removed both of these speaker grills on our Gen 1 as the speakers where producing a rattling noise when traveling over a rough broken tarmac surface.
The speaker grill has the speaker clipped into the rear and can be unplugged from the wiring loom.
Another rattle that bugged us for ages, was hard to locate but we nailed it eventually.
One day, after numerous failed attempts, my wife just reached up and pressed up on the white surround that housed the interior light and the control panel for the sky roof - bingo got ya !.
These item can be easy (ish) to fix, but hard to locate in the first place.
Same fix for both, strip out the items and install some self adhesive silent tape, rebuild and refit.
Hours to track down and locate and about one hour to fix the lot.
This is the problem trying to get the dealer to locate the problem in the first place.
