Question about Car Audio & Video
I have a Boss 4400 4 channel amp. It is currently bridged to two subs and at first after ten minutes of running it the red "diagnost" light comes on. After four days now Green "power" light is on but not producing any sound.
Plz help us out
It sounds like the power supply may have failed. I'm not familiar with that particular Boss amp but many amplifiers will light the power indicator even though the amp isn't operating.
Have you checked your speakers to see if they're blown?
Have you checked the wiring to make sure the speakers are still connected to the amp?
