You will need to construct a panel which will hold the new 6.5" speaker. The stock Supra housing holds a 4"- three hole mount speaker. I have seen people cut the factory housing, use a bit of fiberglass and make a 6.5" speaker fit in the factory housing. I believe it is easier to just construct a mounting ring that attatches to the 3 factory mounting holes than doing the "rig" method and glass the factory housing. By building a new mounting ring you will then be able to get rid of those worthless stock grills that are 7" but only have venting for the factory 4" speaker.
If you find it too much of a pain in the ass, I will build you a set of mounting rings that will allow you to install your MB Quarts. If you use my rings and completely sound dampen the door your mid bass response will be rather amazing with even the stock amp pushing them.
Just resist the urge to mount the speakers on the outside door panel without the inside mounting ring. (ie. removing the factory housing and mounting them to the inside door panel). Doing this will cause you to break the door panel by closing the door. The stock Supra door panel is not cheap.
Mounting rings for MKIV Supras are $150 plus shipping.
