Invest the $800 and wait for it to grow to about $5000, then start your upgrade. 
Seriously, $800 would not do much for stock improvement, you need new speakers and amps. A new HU would be a waste w/o ditching the Bose. I'd use the $800 for sound deadening and stock speaker replacement from Dennis at DoubleD ...

If keeping the oem radio, $800 can do...
DIY ADD-GM24 adapter (see C6 audio sticky) $20
Cubby sub box w/10" sub $400 tops
Bridgeable 4-channel amp $200
Misc wires & amp kit $50
$130 left for 6.5" components in the doors
That would sound pretty good
Save up a bit more to get better components and it will sound great.
Once amp/speakers are done you can decide if you want a new HU while saving for it.

good advice.If you increase your budget, it would allow you to go with better components for the fronts. That's the key. Changing from a $200 amp to a $300 amp won't buy you a big improvement in SQ, but going from $130 to $230 components will.

Opinions are more divided on the rear speakers. Those that are going for optimum sound quality and imaging run without rear speakers and put high-quality component in the doors with plenty of power from aftermarket amps. If keeping the factory amps or doing a more basic system replacement, the rear speakers can provide "fill" and boost the volume of the system.
