My amp turns on but the green LED stays on. Also when I turn the volume up, the red LED goes on and the red light under the JBL logo keeps flashing on and off. What could be the problem? Overheating? Voltage problems?
Thanks.

Fuses are fine. When I have the gain at zero the amp is fine. Once I turn up the gain, the red LED comes on and the red light under the JBL logo starts flashing with the music. Also, the trunk light turns on and off so I think something is wrong with my electrical system. I checked ground and reconnected the amp and still had the problem. Anyone know whats wrong?

if your music is turning off with the red light, its cuz not enough power (voltage, cap, battery, weak alt)
