Altering door to fit 6.5 splits.

Hey all, first post, here it goes

I have recently bought a pair of 6.5 " pioneer component speakers for my subaru impreza rx.  However, the stock speakers are a mere 5.25".  How would I go about altering the current bracket to fit the larger speakers?  Should i just use a hacksaw to modify the size of the hole to make it fit?  I do not think it would be to difficult.

Thanks

Oh yeah i forgot to mention that. The speaker magnet (with the spacer) was very close to the window glass so be very careful if you are cutting the metal to fit the 6.5" speaker cause it might prevent the window from rolling all the way down. Good luck

Example of a homemade spacer.  I used some particle board that was salvaged from some thrown away furniture (not the best material to use but it can be waterproofed pretty well with urethane).  The surface is white because that was the paint color of the furniture.  Cut the piece to fit your door;  the door panel will hide its ugliness, so it doesn't have to be pretty.  Cut the hole so that the speaker fits into it.  In this case I recessed the hole with a routed mortise so that the driver fit flushed.  The baffle is screwed into the door sheet metal and then caulked all around the edge for a good seal.

Keep in mind the room that is needed between the driver surround and the door panel that you have to put back over it...as well as (mentioned already) the room behind the driver's magnet.  You can fit just about any size driver into any size hole using a baffle like this.  This one is a 6.5 driver fitting into a 5.25 hole.
