How to troubleshoot an amp
To make sure the amp is really the problem, look to the side.
All amps have a green power led light and a red protect led light.
If both the green or red light are not on, then continue to the next steps.
Make sure the power is connected securely to the battery and connected properly to the 12v terminal on the amp. The rem tells the amp that the radio is on and it should be too.
