can i ask how you managed to get the z1 to fit so perfectly in the center of the opening? i have had mine in for a while now and have just about given up...i can't get it to sit perfectly in the center of the double din hole to save my life. mad (Anyway...i just tore out all my upgraded stuff this last weekend and did an overhaul. Out went the lower budget stuff i thought would cut it and in went MB Quart Reference 6x9 components in the front doors, 6.5" components in the rear doors, and an alpine amp to drive 'em all and more dynamat than i ever imagined would fit inside the door panels. [LOL] Well...good job and hit me back...i'm dying to get this thing resolved and just sitting evenly...)
