So far ive hooked up the head unit, run the wires for the amp, mounted the amp and hookep up the sub. I ran out of time last weekend because everything proved to be more difficult than I remembered from previous installs. I wanted to be patient and make sure everything was done correctly. So far the sub sounds fantastic. I was a little worried about having too much airspace but it sounds perfect. I tuned it at 63hz LP and it hits enough to feel the kick and gets plenty loud without drowning out the mids and highs. I turned it up and got outside the car with the doors closed but couldnt hear a peep. It makes me really look forward to wiring up the door speakers and laying down the fatmat.
