Saabpunk4life is exactly right! If you haven't had this happen, consider yourself lucky! The guy over at Saabradio.com has made a killing on fixing them. Sure, some are caused by drinks spilling, windows left down, seals being broke,ect... but I can tell you that none of these happened to me. By the looks of it, a lot of other people didn't have these problems either. I am in Indiana, and it went out after we had several bad snow storms. This was the most likely cause given to me by my dealership and the guys at Saabradio.com. I'm a firefighter not an electrician so the info I have was given to me by people who do this for a living. They all stated that Fiber Optics are very sensitive and don't need to be in a flood to be fried.
They also don't run near as hot as normal coaxial powered amps. I'm not saying put 5 layers of rubber wrap on the whole thing, but sealing the bottom and a little on the sides shouldn't make it too hot. (in my thought)
The fan idea is actually very interesting and I may run a power line from the battery to a switch I could mount under the seat then to the fan. (Again, not an electrician and will get some wisdom from one before I do this)
Speakers....
I have narrowed it down to these...
3 Dash speakers:
Infinity Reference 3032cf 3.5" -$69.99 a pair
JL Audio TR350-CXi 3.5" - $69.99 a pair
Kicker KS350 3.5" - $59.99 a pair
(cant find the Bostons that fit but would like to get info)
Door Speakers:
Infinity Reference 6032si 6.5" -$99.99 a pair
Infinity Reference 6030cs 6.5" with 2 tweeters- $199.99 a pair
Boston Acoustic SX50 5.25" with tweeters - $199.99 a pair
Polk Audio DB650i 6.5" with tweeters- $199.99 a pair
Rear Shelf Speakers:
Boston Acoustic S45 4" - $79.99 a pair
Infinity Reference 4032cf 4" - $89.99 a pair
Infinity Kappa 42.9i 4" - $129.99 a pair
JL Audio C2-400X 4" - $139.99 a pair
Polk Audio DB401 4" - $79.99
What would be the biggest bang for my buck and is there any others that I should be looking at? Can I go larger on any of the stock speakers? I have no history with Infinity, but from the threads I have seen, people seem to like them. Boston, Polk, and JL I know and like, but are they worth the extra $?
