AMP doesn't work

[BRJON]

Hi guys, I installed the Hertz Mille ML Power 4 in my audio system.

Although it was successfully started, all the LEDs were on at the same time and the audio was not working properly. I tested the AMP power cable, remote turn on cable & ground cable. They are all working fine (12v) (0hm) The RCA harness is also working fine. The fuse was burned out earlier but I have installed a new one. (The blown fuse may have been caused by a faulty wiring connection, in the previous test only one of the door stereos could make sound and the volume was very low and the sound was not clear)

I found the problem when I tested the audio wire, after I started playing music (the audio did not produce sound). The ohm value of the door audio harness kept changing from 0 to 3.8, while the subwoofer's ohm value was able to reach up to 2.5 ohms. But both of them get 0.0 AC power from the amp. I have tried reconnecting the power to the AMP and tested it after unplugging all the harnesses except for the power, ground and remote control wires. It remains unchanged.

I would like to know do you have any idea about that. Thanks for any answer!

Mixed Mono has also been around for many years from the 80s as well. Ill use a set of 4 ohm components with a passive Xover and throw in a 4 ohm mid in the mix on front stage at times.
