Highliner w/ built in speakers (from lmc)

[wwotr]

I'm looking for alternatives to destroying my doors in my GMC for speaker placement.
When I owned my 67 C-10, I had the High Output "Kick-Panel" speakers, along with 5 1/4" in the doors.
I was not happy with the sound.
The Speaker placement was too low and between that and my Hearing Problems, the sound was Distant/Muddy.
So when I got my LMC Catalog, they have a Highliner, which is a unit that goes on the Headliner and has 4 Speakers Total (2) for the Driver & Passenger right above your head. The Head unit installs up above, so your Stereo and Speakers are contained IN the Headliner.

You can see it here at:

I was wondering if anyone has installed this (or similar) and how they liked the Sound/Placement.
