Rotun's install is very nice, I especially like his custom work on the sub and the rear doors.

When it comes to speakers the most important thing is to listen to as many different brands as you can with the music you like. Make the decision on YOUR sound tastes not somebody else. MB Quarts are nice speakers, I ran them back in a set up I had in the 90's and left them in the car when I sold them. Just never spent the $$$ to replace them in my set up. I'm just running some cheap Pioneers that do the job.

Again, make the decision on YOUR sound tastes not somebody else. Take a CD or USB stick and spend the day cruising local sound shops to listen to different speakers.
