How is your gain set? Could just be a bad amp. It is a bottom-end brand. ------------- Support the12volt.com

Your gain is set very high!, that will cause it to clip and cut out. What head unit do you have and what is the rca pre out voltage?

No, don't just "turn it down a bit" you need to set it properly. Use the search function on this forum for "setting gain" and do it correctly. ------------- Support the12volt.com
