2009 Si Sound System Upgrades

I just got an 09 Si, and am looking to upgrade the sound system. I was looking for some opinions, as there isn't too much talk about stereo upgrades for the 09 yet (Crutchfield hasn't even fitted speakers to it yet):

Has anyone tried fitting an aftermarket subwoofer to the original subwoofer location? Is there room to fit a speaker larger than 8" with a bit of modification?

If I replace the subwoofer and power it with a dedicated amp, would the rest of the speakers then get more power/better clarity?

Is the deck decent? 350 watts (assuming I add a dedicated subwoofer amp) is a good amount of power for the system. If I upgrade the speakers, would the stock deck be sufficient?

Does anyone know what company actually manufactures the electronics or the speakers on the 09 Si's?

I know this is a lot of questions, but any help is appreciated. If anyone has made modifications to the soundsystem on their 09 and has some pictures, please post them, I'd be interested to see some ideas.

Thanks for the advice.

I'm guessing nothing has really changed audio wise in the 09's...The factory deck isn't too bad at all....There aren't many options for replacing the factory sub...I definitely don't think anything bigger is gonna fit even with modification, the hole isn't that big. I'm sure there have been a few people amp the speakers with stock deck. Search in the audio section. Tons have done set ups.
