I remember when I installed it last it was working. There was sound coming out of it. But then I come back and turn on my system the amp does not work any more. I had my system installed professionally. But the mrd...I installed myself. What I have is two mrv-t420 just runnin to the speakers and stuff. I was thinking maybe the power effected the rca's? What they told me at the place where I got the rest of my stuff installed was that the mrd amp was not sending any sound to my eq. They tried different rca cables and stuff but no luck . So I think that the rca jack is not working right.....I was wondering if it was something I would be able to fix myself because I have no more warranty on the amp. Sorry about the length....Thanks.

The amp is not sending a signal to your EQ?  Nah, whoever told you that doesn't know what they're talking about.  Post a list of all the equipment in your system and how you have everything connected.

go to mode 9 on the amp and change it to "off"   Mode 9 should be your safe mode.  The amp will turn on and everything, but it will not work.   Its a safety feature.   Check it out.
