And all I can say is WOW! I did the MB Quarts 6.5" in the door (with my custom mounts I made) the Infinity 4 ways in the dash, a 6" 100 watt Bazooka sub in the passenger well... and a 4x100 infinity amp in the front trunk to power the speakers. What a project... but what sound. Incredible difference from what I had!!! I am very happy as you can tell!!! And I kept the factory HU.
