The wheel is getting refinished so we'll see how that goes. Not sure if anything can be done about the dash.
At least that one is small.
I have SoundSkins in the doors and trunk. Turning up the gain on the amplifier today made a big difference. But I still feel that tweeters are too bright to be placed by the windshield. Knowing what I know now, I would try a 2-2.5" in the factory location and see how that plays with the stock system. Add some 6x9 subs to the rear deck and be done with it. But while it would add lows and highs, it needs a time alignment to make it all sound cohesive.
Ideally something like these in the dash

with 6x9s in the doors

some kind of slim woofer in the rear side panels, and subs in the deck

all run off an 8 channel amp/DSP via optical connection.

If that doesn't sound good maybe try the NAVTV, if that still doesn't work it's not worth spending more to me.
