Perhaps someone here can tell me if I might have a problem doing this since I've gotten conflicting info elsewhere.  I want to connect the speaker outputs from each of my Class D Audio SDS-450 mono amps, which have a floating ground at the speaker outputs, to my ACI Force subwoofers.  There will be one sub for each SDS amp.  The sub amps only have line-level inputs but came with speaker to line level converters as follows:



The sub amps have an input impedance of 10K ohms.

Will this work or am I in danger of damaging either my amps or subwoofers given that the speaker outputs have a floating ground?

Thanks in advance for any advice you can provide.

could you provide a link for the info of your power amp?

The o/p of your amp will be held 100ohms above ground and the amp will see about 25k of resistance from this circuit. more info when I see data about the amp.

A lot of info (too much perhaps to weed through) about these amps in this thread http://www.audiocircle.com/index.php?topic=76400.0

The actual amps in question are at http://classdaudio.com in particular the SDS series. I'm running a pair as monoblocks (full bridge mode).  Not sure it will have the added info needed.

Thanks!
