What material did you use to sound proof?
I used Fibreglass Evercoat Q-Pads Sound Deadener inside doghouse and on some areas of floor, than installed Dynamat Hoodliner 3/4" Thick Self-Adhesive Sound Deadener over top of Q-Pads and under the floor on both sides of doghouse, under drivers seat and passenger seat.
Don't reley on the self adhesive to work by itself, I also used spray adhesive before install to insure good contact.
My noise level is very low now, almost can't hear motor or fan, much better, total cost about $400 and was worth every penny.
