I'm all for overpowering speakers vs. underpowering them. Given the speakers you listed, you should be able to get massive output from 2,000 Watts...
I think that the best way to be certain is to use the output from the factory amp as input for a pre-amp/processor (something like an MS-8, Bit...
No worries on the power from the battery...you could easily go up to 1,000 watts RMS before you need to worry. I say leave the factory amp because...
You would be best off to leave the factory JBL amp in place and use the output from it as inputs to the MS-8...rather than trying to get inputs...

Polyester fiber-fill (pillow stuffing) works well...you can pick some up at WalMart or any fabric store. Do not pack it full, rather loosely fill...

The short answer is "no" unfortunately. The signal coming from the factory head unit to the JBL amp under the passenger seat is a digital signal....
I can confirm that the JBL system has 8 separate channels coming off the amplifier to the 8 separate speakers.
Sometimes it's just easier to mount an amp to a board. It allows you to sink screws in more convenient places (than the amp flanges might...
