Need Help With Building DIY Grounding Cable


I am planning to build a DIY grounding box. I am planning to connect my DAC and Integrated amp to this grounding box by connectig the unused RCA input terminals on the both. For this I need to create two cables with Banana at one end and RCA at the other end so that I can connect them via speaker binding post on grounding box.

I need help with how & where to attach (solder) the cable on RCA socket.

I also need help in understanding if I can connect both L & R RCA input sockets on same amp to same grounding box (assuming I am going to solder the wire on the shell/-ve part of RCA connector)? Also Can I similarly connect all unused inputs on DAC/Amp to grounding box.

I understand attaching multiple inputs to grounding box is not going to amplify the effect & I just want to do it for protection of those input terminals.




You might want to post this question at     Also, I recommend building two separate ground boxes - one for analog, one for digital.  Surprisingly, I discovered that even the ground wires can pass along digital nasties to analog.  When I re-routed them separately, the SQ cleaned up.  

@steakster Thanks for your reply. I am going to build two grounding boxes, earlier my plan was to make 1 bigger one..but now changed it making 2 boxes with smaller dimension. I don't have account on DIYaudio, so thats why I am hoping someone would answer all my queries here.

I have built 3 ground boxes. 1 each for my speakers with subs built in and one for my system power conditioner. I have them posted on my virtual system. I have noticed an improvement using them.
I connected my main ground box to my power conditioner’s ground lug spade to the ground box with banana. My speakers are connected spade to banana.
You can connect individual components to the box directly as well using one open rca or use one component (Amp) as a component hub connecting all components to the amp then only the amp connects to the ground box. Some use alligator clamps on open rca input but I feel rca connectors stay connected better. I soldered my rca’s to outer ground connection. I have not needed to separate digital and analog. Good luck with it. Fun stuff.

Check out this link very helpful ground box info. I own one of his RF Router for my HT system. Also, search agon thread on ground boxes.
