Twelve years ago I had Polk components installed in the doors of my Mazda Precidia. A couple of months later the drivers side midbass was fried because it got wet? What should be done to protect door speakers from getting wet? I am worried about rain water from above and rustproofing oil spray from below? I have a 2001 Mazda protege now.

I had the same problem with my polks last year. After 2.5 years in the car, the moisture in the door caused the glue holding the back plate and pole piece let go. When that glue crapped out, the pole piece shifted and siezed the driver.
Two things you can do
(1) XTC foam baffles
(2) Rubber boot for the motor structure (I'm pretty sure the Polk MOMOs come with those)

Reading Joe Pettitt's High Performance Car Stereo and he writes "... if you're planning a very high powered system, you should reinforce the door panels. Better yet, make a small enclosure to house your midrange driver." Is a small enclosure for a midrange driver a practical solution? I like the idea of this better than sound deadening the doors. He also writes "... if you're just installing a system with a hi-powered head unit, 25 watts or so, you probably won't need to reinforce the door panels with fiberglass and laminating them with sound deadening material. Wait till you've got two or three high powered amplifiers...". I've got one (not two or three amps) and will not be using my deck power. So at a minimum I will use XTC foam baffles, may build a midrange enclosure (depending upon replies) and will try to avoid expense of sound deadening. Do I make sense? I apologize for my verbosity.

^^ well I only have one amp in my system so I have to wait? And ya I don't use any head unit power/amperage either. Mmmm Anyway sound deadening is just that. Let me get this right the moisture is getting by the window. So yes enclose the speaker away from the moisture. Kinda like bulding "pods" no? This would have an added benifite in stoping ( or slowing down ) outside noise coming through you front stage.

Where can I buy XTC foam baffles in Toronto (or Canada)? Crutchfield only sells in the USA. Parts Express charges $16USD to ship a $6 piece of foam. Will order from PartsExpress if I can't purchase locally or in Canada.

^ Any decent custom shop should be able to get them. They are distributed by DLC in Canada.
Canadian Tire may have a plastic version in stock as well - better than nothing.
Also - I don't agree with the midrange box in the door. Some mids may like it but most were designed to work in a door, not a tiny little box.
