I am working on a class D amp build and will be bridging 2 power amp modules. Do I need to ground both modules together to run my 2.3 TLs with the SDA cable?
Is this even in the right place?

post a schematic of the amp.

Don't have one. The modules come pre assembled and are wired to the power supply module on one end and the input/output on the other. "Class D Audio" supplied the boards.
Looks like the modules get grounded to the power supply board which is grounded at the xfrmr. Is this what is meant by common ground? -
Bridged/balanced amps are NEVER common-ground.
You run a bridged/balanced amp, you'd better have the AI-1 or aftermarket upgrade. -
Ahaa. Thanks very much Schurkey! Now how do I get one of those?

The link above is the best start. There are many other threads but that's the one to begin with. Search for "Dreadnought" (proper spelling) and also "Dreadnaught" (commonly used spelling) on this site.
