I am still noob compared to many here and hence understood half of your response. So amp cannot take balanced signals as per specification but people still use it..?
I am having issues with the amp. On low gains it sounds fine but when gains are set propely, it does not sound good and clean.
If I send only +ve signals from HU and no -ve, would it work better?
(P.s: I have used the same amp + sub in my wife's car with Alpine HU from sub pre-out, and no issues there. So amp and sub are 100% working.)
