Hello All,
This is my first time posting and my first amp build. I'd appreciate some feedback even though I can eventually sort this out. I'd like to do further research but am limited in time due to family commitments and work. Once completed, I'd be happy to write it all up for the community. The customer support from Ghent has been helpful.
I'm building a monoblock amp to power a subwoofer. I have purchased the ICEPOWER 1000ASP board and the Ghent GK-ASP-MXR case. I chose the case with both the XLR and RCA to have flexibility in future stereo endeavors. However, if that imposes a lot of trouble, I'd be okay with just hooking up the RCA for now.
Here are my questions:
1. Ghent also sells an RTX module that converts an RCA input (+/GND) into balanced signals(+/-/GND). I'll be starting with an RCA input and possibly switching to XLR down the road. Do you all recommend the RTX module? This is only a subwoofer so I'm thinking the loss of quality may not be unacceptable.
2. If I choose not to use the RTX module and just do RCA only, would I just connect the board + signal input (P2) to the XLR connector, and buy an XLR to RCA converter cord?
3. From the AC connector (P3), I appear to have an extra black lead for the ground wire. I thought it would cut off the connector and attach it to the case ground screw just to add extra assurance the board is well-grounded. Any input?
4. When I do go to test, what do you all recommend for safety if I have to open it up again? How much time might be needed for the capacitors to discharge? A week?
For reference, the amp board data sheet is here:

Thank you!
