Stereo & Electronics - TA Rear Seat Side Panel Speakers

I bought my '97 TA WS6 Monsoon with bad speakers all around.
(How did they all go bad?)

I thought great, this will be cool, I am justified in upgrading. I will keep the Amp and just upgrade the speakers for a clear hard driving sound. Easy right?

After reading many many threads and spending hours looking for Fosgates (good luck with that!) here is what I came up with:

Hatch area = Alpine SPS-100A - $45
Door Tweeter = Alpine SPS-1005 - $25
Door Mid - Infinity KAPPA 62.7i - $60 (2 ohm!)
Sail = Rockford Fosgate RFP4406 ??

I did find two seperate new Fosgates on Ebay but I bid one up to $60 before giving up and other deal required Paypal which I do not have. There are no other RFP4406s on the Web. And as you all know 6 3/4" 4 ohm subs are hard to find.

The only 4 ohm subs I could come up with is - Kicker 04SSMB6

These are kind of pricey, will they work? Any other woofer, mid-woofer ideas?

Thanks.

Wait! I just noticed this:
Pioneer Premier TS-M7PRS

These speakers are also a bit pricey but they get great reviews.

Did I answer my own question? Doh!

I have:

Door: Rockford Fosgate Fanatic Q 6.5" Components
Rear Seat: Rockford Fosgate HPC2206 6.5"
Hatch: Rockford Fosgate Fanatic Q 4" Components

I'm not sure what you mean you are having a hard time finding Fosgate's?

He's talking specifically about RFP4406's which are listed in the Monsoon sticky's but were discontinued several years ago.
