Since you say "non NAV" I will assume that you have a C6. You can get marginally better performance by swapping out the 3.5" in the doors and maybe the 5.25" in the rears with coaxials. I wouldn't bother with the dash speaker, it doesn't carry much of the sound stage. My recommendation would be to replace the two 3.5" speakers in the doors and see what you get. Folks have used Boston, Infinity and Eclipse speakers for this, depending on what you like.

I'm going this route - just ordered Infinity replacement 3.5" units for the doors and dash.
One thing I noticed after ordering is that the Infinity Kappa speakers are 2 ohm impedance - I assume the Crutchfield
site would not have recommended them if I could only use 4 ohm speakers....right?

Unfortunately it's a slippery slope. Speaker swap will give you a marginal improvement. After that it's a new amp, sub and front speakers. You have to define your goal. If you think that adding some real highs (the Bose system has no tweeters) via the coax will be enough then go that route. But if your goal is a truly good sounding system, starting over is your only choice.

BTW - was the install on a Corvette or another vehicle? If it was a vette I'm curious to know what kind of difference it made.
I'm also looking at putting the 5.25" Kappa's in the back, but I'll take it one step at a time....then again, why not just do it while I'm at it....
