Has anyone accessed the lower dash to replace the UHFS amp?

[Muzzman1]

I got my hands on a LightHarmonic amplifier to try out on my wife's Model X. I installed on on my Model S, but ran across some instructional videos.
(the LIght Harmonic amp is a bolt in replacement for the stock UHFS amp)
Has anyone done it, or has anyone seen any video's posted?

Thanks!
