Hey bro I have had the jag35 PCB board for the headway setup and the jag35 74AH Lev60 pro V2 and BOTH batteries saw around a 10-15% power increase on delivery by upgrading from the PCB to bus bars for some reason the PCB board restricts the current flow there are several videos showing this on the test bench but great video and nice setup
That mfka jammin,, I have that same radio wine and can’t get rid of it 😭😭.. did the wire wrap around the rca’s.. nothing. Re tightened up the grounds .. nothing 😤 idk what it is at this point.
I saw a video terry tbo ray posted on this same problem and all he did to fix it was grounded the head unit literally pulled it out and added a small screw to the frame of the head unit with a ground wire to the frame and 🤯 💥 no whine
