The speaker did end of fitting after a little engineering. They did came with spacers which I ended up using just in case. I was only able to actually only use one of the hole on the door to screw in the spacer. With the other 3 holes, I ended up using washers and screws to wedge it in tightly (hard to explain without pictures).
Could you maybe explain or show pictures on how you used washers and screws to wedge it in tightly? I have the exact same speakers, and I'm having trouble getting them to fit.
How does it sound with the new head unit? I have an aftermarket head unit too, and I'm hoping they sound good.
Thanks for any help!
