I have a question regarding the new satellite outdoor setup with sub that Triad has. Is the sub buried or above ground? seems from the site that it is a cabinet above ground but then some drawings show below ground? Also the main set, how many satellites? Finally, what amp runs the full set? a rack amp 350, saw mention of it on the site? how does everything hook up? oh ya does the amp have a line in for 1/8" stereo. i want to hook it up to one of the non amped zones on my nuvo grand concerto. right now those zones hook up to nuvo amps with a 1/8 mini stereo jack.
