Question about Car Audio & Video
You do not specify the make and model of your amp, so it is not possible to point you to specific troubleshooting information. However, some problems are generic and it appears that you have already isolated the problem to the amp itself.
It's still possible that the head unit does not provide a strong enough input signal, but your amp should have a level control that allows you to match it to the head unit. I'd also doublecheck the other amp settings. If the setting check out, it's likely that the amp is defective.
Hope this helps.
