What car do you have? In your first picture, it almost looks like you have 6x9's in the rear deck - but maybe that is just the way it looks because of camera angle or something?Yes, easy as heck. They already have a thick reinforcement ring, so it won't vibrate. My speaker holes weren't the same diameter, so I drilled them at an angle and I can hang off that thing if I want. Oh, I did have to peel a sound deadener cover off first. View attachment 994862 View attachment 994863
Also, how did the 8" sub work out for you? I've never heard anyone that actually thought they performed well in the rear deck - just curious what you think.
Lastly, where you able to reinstall the "cover" after the sub was installed in the rear deck? Or doesn't it fit anymore because of the sub?
