Hi, I have built an amplifier using the icepower 50asx2SE board and I have the Case kit from Ghent Audio for it. Im only getting sound out of one channel at moment nd not sure why. I have gone through and checked continuity through all the cables and they are fine as is the soldering for the speaker terminals and the RCA inputs. Now I was watching a video made by a Youtuber DIy person, TOIDS and he had a video showing the build. One thing I noticed was that the color coding of signal cable included with the case and what is in the cable kit only. I had ordered the cable kit before deciding to just get the case form Ghent Audio as well. Also the diagram of the cables in the manual for the board is different. Im confused. here is a picture of what I have. Now the way I wired it was usng the first cable that caame from GHent with the case. Pink went to pos or right RCA and Black went to negative. Then for the next RCA or the Left It went Black to center and the white to the ground lug of that RCA. This is how it was shown in Toids. Fire it up and only one channel the right. Can someone please clarify this for me and psibly tell me wher Im soldering these guys too. The diagram hows the cable even more different that these twom with looks like two wires with a ground or some thing tying the last two??? I dunno Im burnt been working on this all day.

Fixed it, I had the signal cale wired wrong. All good. Sounds great but not as powerful I guess that I anticpated but I am driving ELac Ub51 straight out of my dacs Variable output. Pssibly need a buffer? Im running the Beresford Caiman 7520 currently and a Mojo
Pic I attached is upside down to your picture.
For Channel 1 - Input Positive is RED and Input Negative is BLACK (pins 7 and 6)
For Channel 2 - Input Positive is WHITE and Input Negative is BLACK (Pins 5 and 4)
As long as all other connections are done correctly.
Your pic you posted --- RED/BLACK/BLACK/WHITE wires connector --- Red and Black INPUT wires go to your RIGHT Input RCA Connector - RED is CENTER (positive) and Black is the Lug(Negative), then the WHITE and BLACK INPUT wires for to your LEFT Input RCA connector - White is CENTER (positive) and Black is the Lug(Negative). Sounds like opposite of what TOIDs video showed you.
Sounds like you have the Left Channel RCA connected backwards? But could be something else, because if connected correctly, you would get signal, but be out of phase with Right channel.
The pic below is from Parts-Express.com, search for 50ASX2SE, then go to the Manual&Resources link towards the bottom and pull up the datasheet - has very good pictures and descriptions for hook-up.

I'm too slow, or you're too fast. Glad you got it going. Yeah this is really meant for at least 4 ohm speakers, and better yet 3 ohm. Otherwise you are only getting 20-30watts at 8 ohms.
My speakers I’m driving are the Elac Unifi Ub51 at 4ohm and love some juice but sound wonderful at low volumes as well. My other current set is a set of a/d/s Sat-6. I also drove them with TPA3355 and that gets louder by far albeit its supposedly much higher wattage. Only had short while to test it iurd
