Awesome! I ordered the same speakers and brackets you did (cause I’m unoriginal like that).
My OCC acquired an aftermarket CD player (late 1990’s, I’m guessin) that I took out and replaced with a GM factory stereo.
So I’ve been sorting thru some hatchet-wiring. Reason I bring all this up is to ask....is speaker polarity important? If I have it backwards, does it effect sound quality/component longevity?
On an unrelated note, let me remind you how lucky you are to have a missus that appreciates wagons! Not all spouses are down with B-bodies, and, umm, makes it harder, uh....what I’m tryin to say is....the speakers I just ordered are being shipped to my work.
