The Capacitor block was blinking because the device it was supplying a filtered DC voltage to was drawing a lot of current. Your amp has a fault somewhere, more than likely the power stage. Could be a shorted output transistor.

Amp Power LED Display blinks red and no sound


With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. Does the voltage on either the B+ or remote pulse below ~11 volts when the LED flashes?

Generally, the power light is green and the protect light is red. If the protect light is on there could be a short in the wiring or there could be an internal fault in the amp.

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down (goes into protection), the amp likely has blown output transistors.
