Adapter plates for Bose door speakers

Guys,

I know that many of you have replaced the Bose door speakers in your RX-8 with upgraded models, and that to do so you needed to fabricate an adapter panel to bridge the 8-inch hole in the door.

I plan on replacing my door speakers with Alpine SPR-17S 6.5-inch component speakers, with the tweeter placed up in the sail panel by the side mirrors.

Would anyone here care to sell their services to fabricate an adapter panel for each of my doors? I know that it's not rocket science, but if you've got the tools and experience and your price is fair then I'd appreciate it.

Lexan and a jigsaw should be all you need.

I made mine with a dremel and lexan. Not the prettiest things ever, but they work. Took me maybe 4 hours all told. I spent a lot of time trying to get them rounder with a sanding drum, and kind of succeeded.

crutchfield will give you free adapters if you buy speakers from them.

I tried that on the Crutchfield website and the only speaker choices they provided were for the rear deck, *not* the doors.

And the only adapters they showed were to fit round speakers into 6x9 holes.

Didn't realize anyone made a 9" to 6.5" adapter plate. Would have saved us all a ton of work.

I did exactly as Socket did. I highly recommend a nice thick piece of Lexan over the cheap Plexi crap. Thin or thick plexi chips and melts like crazy as you're cutting it. I cheaped out and ended up redoing it correctly with Lexan.

Same thing happened to me. Their system isn't set up for replacing the front bose speakers because nothing aftermarket would work with the stock bose amp.

Drilling holes in lexan should be done very carefully too. In my experience on an earlier project, if you chip the lexan when you drill a hole in it, it will crack from that chip to the nearest edge. This time around I used my dremel on its lowest speed setting and an old drill bit, then slowly drilled through. It was very easy, you just have to take your time.

Thickest stuff Home Depot or Lowes carrys. It's certainly not what I would call thick. But it's the thicker of the two or three thicknesses they carry. For some reason I'm remembering .097 ?!?! I think that's their cheap thin stuff.

I used quarter inch lexan i bought from OSH.

If you can find 3/8th inch lexan, That'd be even better.
