Wow... that's a lot of weight. You're almost 1k lbs over stock with driver!
I'm afraid you may be right about your last conclusion. A stiffer spring rate will help BUT it may still be bouncy due to all the extra load AND anything over a 10 spring rate on rear will not b compensated by shock valving. At the end of day, no guarantee you'll solve anything. You'll have this issue regardless of what coil-overs you run - the kits are designed and R&D for stock applications, never intended to add 550-1000 lbs of weight.
This is the same thing I was asking you about Ken, although I am not adding the 300lbs of driver weight, pretty much the same situation.
So, bottom line, take out the audio or live with the ride quality, I guess.
