Alpine Amplifier Problem	Sign In

I have an Ampine MRD Series amplifier. Around 700 watts MRS. It turns on and shows it's display and menu, but has no output voltage. I tested everything with my digital multi-meter, and everything seems to be working, except for the speaker outputs.

Any idea what part this could be, that I need to test to solve my problem?

Thanks in advance.

I would check to see if there are any fuses in the amp that are blown. If not, if it's wired correctly then you are probably looking at an internal problem......

Has the amp ever been bridged? If it was bridged, and was done improperly this could cause the amplifier to fry the internal computer.
