Actually, go with the wiring in the diagram above. I don't like running stereo channels to dual voice coils without the ability to separately set the gains. Too much variance.
There is nothing wrong with using a coil on each channel as long as the signal is the same...usually the subwoofer output is mono.
Doesn't matter if one coil is getting 50 watts and the other is getting 150 watts...there will be nothing wrong with that.
Para,
I'm just curious to know if your mounting that amp in the factory location?
I'm wanting to do something similar to what you're doing. Upgrading the sub, but leaving in in a factory location.
I use my storage space way to much to put a big speaker box in.
Depending on what enclosure you are using, it might want a bit larger enclosure...

Polk Audio and Infinity are both very good quality speakers, I don't think you would be disappointed with either of them. The weak spot would be the stock enclosure...
Which OEM enclosure are you using...?

Add about .25-.4 #'s of polyfill to the enclosure and it should be dead on the Polk specs. You can buy it in 1# bags at Wal Mart for like $3.
i'm assuming Infinity08 measure was in pounds.. so should i put about 1/3 of the bag in the enclosure?
Im using the same box as you, what did you use to fill in the gaps from the "pocket" things in the plastic. When my sub is mounted those holes are still showing a little bit making the box unsealed.
