I think you did a great job. I would have liked to have seen a little more fiberglass for the base of your box. How thick was it? Here in Boston it is all about stealth, factory looking systems. The nice thing is that you have a great foundation laid any future upgrades when you get the itch. We did a 2011 Impreza with multi amps, fiberglass sub box, speaker upgrade, hushmatt, suede and left the factory head.He eventually upgraded to the Kenwood DNX-9980 and loves it.
