Hello everyone.
I have bought an '83 924 about two weeks ago, all bone stock except for the aftermarket stereo head unit and the AC system from the 924S.

Last week i have replaced the stock 80's rear 4x6 speakers with a pair of JBL Stage3 6427's. Needless to say its an improvement yet quality still isnt as good as i'd like, and to be honest looking back i would have gone with Alpine speakers since i trust their brand more in the end.

I was poking around under the door panels and saw that there is a hole in the door metal for the door speakers which my 924 isnt equipped with. So here is the thing, has anyone tried fitting 6x9 inch speakers there? Or 6.5 inch ones like the Alpine SXE-1725S.
I am also thinking of installing Alpine tweeters at the base of the A-pillar trims and also perhaps an Alpine amp somewhere, and perhaps something else under the center dash grille which is a vacant space.
Any ideas?
