Thank you see the only shallow mounts that I have ever done were the Rockford fosgate p3 shallow , the mb quart shallow mount 10 inch and the kenwood 12 inch ( non excelon) I really wasn't impressed with any of them but u guess the better of the 3 was probably the kenwood but I am doing a build for someone who wants to save the space and wants alot of bass but he also wants a very clean sounding bass because he has spent alot of money on the highs and mids in the truck thanks for everything
