So If you want full range sound, you'll probably want to consider alternative locations like the TT cabinetry or your own cabinetry design. You'll probably find it easier to get decent speaker wire to alternative locations as well.
I did notice some electrical wiring sitting up in the ceiling cavity behind the speaker and gave some thought to installing baffles like these: http://www.amazon.com/DEI-050330-Rou.../dp/B0039Z3SRA
... to decouple/dampen the bass resonance in the roof that might cause things both seen and unseen from rattling around. I was scoping out possible alternative speaker locations after having a similar thought on ignoring the existing ceiling speaker locations.. the cavity above the tuner head-end unit is a slam dunk, a second speaker would require losing cabinet space and was a non starter with my wife. The baffles seem like a cheap compromise to limit rattling things in the ceiling from the stock speaker locations while avoiding a reduction in precious cargo space. The other "problem" I'm hoping to solve is how to get audio from the undermount TV/DVD player location from the above fridge location to the audio system which would require either running a cable between the two locations or using one of these 3.5mm line level->Bluetooth adapters: http://www.amazon.com/Wireless-Porta...dp/B00BTIM8FC/
.. which will accept power via a 5v USB port <which charges a small internal battery on the unit>.
Hopefully I'll get some time on the roof of my RV this weekend to nail down the second question of what a safe cable routing location will be to run the cables from my solar charge array and then I should be able to get rolling on installation once the humidity drops to a sane level. I'll document the design, where I purchased the various components and some photos of the solar and AV upgrade installs once I get rolling (along with stories of the inevitable "doh-I forgot x, broke y, etc..). Thanks for your insights!
