speaker level sub hookup on class D?


I have a W4S ICE amp and was wondering if it would be OK to use the hi level speaker inputs on my Velodyne DD-15 sub? Reason being that the amp is fully balanced differential something and my sub seems to sum both channels to a mono signal. Since my amp does not use a common ground is it OK to do this? I have already asked W4S and they were not sure. Velodyne tech help is away until after the New Year. I would like to run wires from my amp output to the subs hi level input. Thanks for all replies.

Good to know.....ICE is 'half bridge' topology and makes sense for the whole thing to 'float'.
Thanks for half/full notes:
I think the IR module I have out in the garage is ALSO half bridge. The IR white paper lists some considerations for the designer when choosing to go with full or half bridge.

Isn't the 500ASP also 80v? My spec sheet lists 'Nominal DC voltage 1=50v' and 'Nominal DC voltage 2=80v'
Kij,
Yes, and I'd expect the 250ASP to also have 2 voltages. Since I own the ASP500 I haven't bothered to look at the other 2 modules.

Don't forget...and I don't know how this plays into it, that these modules are designed to power other B&O modules....from another series which are not self powered. So, for the ASP500 powering a lower power module, it may make sense to tap the 50v rail and if powering a 500 watt module, use the 80v rail.

If I were doing 'professional' sound reinforcement gear, this would be an option to look at.
