Default Suitable as an Amp6-Basic PS?

Ok so I'm making a Amp6-Basic boombox (along with the rest of the world) and I've decided to use this: http://www.mini-box.com/picoUPS-100-...-backup-system to manage the power side of things (of course I'm using an AC/DC input in conjunction with an SLA battery).

Now I don't want to have an external power brick, so after pottering around the interwebs I found this: http://www.wellforces.co.nz/index.ph...ypage.tpl.html and this: http://www.wellforces.co.nz/index.ph...ypage.tpl.html which are small enough for me to fit into the electronics compartment.

Also, before anyone points this out: They're meant to be 15V. The picoUPS-100 needs 15-18V, so it can simultaneously charge the battery and provide power to the load. The Amp6-Basic won't be getting 15V.

So... questions:
(1) These two power supplies are the internal equivalents of a big, black power brick right? (Just not 100% sure on this... want know I'm buying the right thing.
(2) How much power do I need? The company has a selection from 5W-48W, I just happened to pick the 15 watt ones. BTW, the amp is driving two 25W Tang Bands.
(3) Which one should I get? There's essentially no difference except for the casing... though I suppose casing would be safer...
(4) Would there be any noise/buzz issues with these power supplies being in very close proximity to the Amp6-Basic? Looking in the specs there's some "ripple and noise" thing which for the cased was 150mV and the caseless 120mV, if that means anything.

Thanks muchly for any help.
