I am currently changing out the entire shaker/sync system in my 10 mustang gt premium, all is going well so far, managed to retain sync/bluetooth/etc, just back on riverboat and cant check something i need to know and wanted to see if you guys can help me, i need to know on the door subs, where the actual mounting lip for the sub, how far does it stick out from door panel, usually the factory trim ring covers this step like mounting area, but i am making a new ring that the sub will mount in but need to know how far the lip sticks out on door panel. Looks to be about 1/2 inch but need confirmation. Any help is appreciated.
