Gah.

I've got a 1994 Nissan Primera SGX with tweeters fitted as standard in
the A-Pillars. They're about 12 mm depth...

Unfortunately one of them just decided to give up over night. One day,
fine, the next day, bad. Can't figure it out.

So a replacement is in order. I picked up a pair of Alpine something or
the other, but they're about 17 mm depth because of the ridiculous
casing manufacturers like putting on.

I need solutions.

There's already a rather large hole in the A-Pillar trip for the
existing speaker grill. But it's misshaped, and would end up that I
would have 0.5mm gap at the top and bottom of the new tweeter flush
mounting kit. Also I don't think I'd get the entire kit securely fitted
due to lack of depth on the A-Pillar.

The tweeter won't fit to the bracket, or under the trim because there's
not enough depth... and I really dislike the idea of making holes.

I also even more dislike the idea of making holes when there's already a
hole.

Any suggestions? Or maybe someone knows of some slim line tweeters? Or
maybe someway to dismantle speaker and casing??? Or perhaps some way of
fitting them stylishly with no holes?
