Great idea, although it depends on how big your A pillars are. I just got a couple from the scrappy, but then realised that it won't work on a mark 2 Golf as they are nowhere near wide enough, part of them are also covered by a rubber seal. The only park that be wide enough is at the bottom and to the inside of them, but of course down there it's too low and the sound will be going across the front of the windscreen toward each other instead of towards you!
