Hi Axel,
Yes, the 'Square Tweeter store was great every time I went in there. I was introduced to & acquired a taste for Bang & Olufsen there. [

I still have the stock speakers & a somewhat later Becker G.P. in the 560. I know if I upgraded to more modern & higher quality components, I'd be pleased. I just really like the look of the dash/console area as it is. I'll probably change the exhaust a little for a bit of V8 burble in the Summer
Years ago (10 now), I put a Kenwwood head & 10 CD changer in my 740 Volvo along with some Boston Acoustics 6X9s under the rear shelf. Made big holes! Tweeter, natch. Just Wed. & Thursday I must have put close to 600 miles on the 740 at
speed with an iPod hooked to a cassette adapter. Sweet sounds the whole ride(s).
Good luck fitting the speakers & Happy Tunes!
