FWIW i ditched my rear 6x9's for 6.5 components. One is blown right now. I dunno what i'll replace it with. Also one channel of my 4chan amp is blown as well so it works out. That's some good deals on those morel's. I might have to purchase those myself.
Also for a Sub what about Sundown Audio, or if you want to go cheap get a Kicker sub. They sound pretty good for the price. I've never been disappointed.
Use something like this on your front speakers. To seal the speakers off to the cabin.
