I have some 6.5 inch speakers just sitting around and I know without the 4 inch speaker pod the holes are 6.5 in the front doors of an 06, LS sedan. What size spacer would i need for it to clear the window but have the door panels still go on. I DO NOT want to cut the speaker grill on the door panel, any help is awesome! Thanks. These are the speakers I have as well : Sony Xplod XS-R1644 6-1/2" 4-Way Speakers ? Walmart.com
