You can cut the metal panels and weld/seam seal a cup section in there.  Other than that, cutting will result in a waterfall effect

Thank you, this is why I ask. I will continue to live with.

Maybe you can do some "out of the cup" thinking here.  First imagine that it is even possible to fit a speaker into a tiny space like your cell phone... much less a speaker that even works well enough to be able to use with the phone held away from your ear when you click the "speaker" button.  With these advances in speaker technology one would have to wonder if an improvement is available for our traditional speakers.  I did a search for "thin" speakers and found a hit on Crutchfield.  I've never used them but perhaps thin speakers like these would be able to fit in the kick panels better:  (as expected, not cheap)

With the use of better magnets, speakers can be made thin.

Take a look at iPods and Bluetooth speakers.

I may have to look into those thin speakers.

Alan…I made my own dash speaker assembly with a pair of Kicker 4” speakers…it’s tight.
Most of those pre-made assemblies have crappy 3-1/2” speakers.
Works great, however limited on low frequencies…that’s what the subwoofer is for.

I found these on Amazon for $54.00-$75.00Infinity Reference 6532EX EZFit 6.5" Shallow Mount 165 Watts Peak Power Car Audio Coaxial Speakers  . I currently have there 6x9s in my rear deck and they crank out quality sound. There only 2-1/8" deep so I think rebuilding the kick panel pods and I should have almost 2 more inches on the floor. We will see, pics to follow 

Good to know tks
