New Rear Speakers & Cut Power Button For PRV175

The PRV175 I have has a problem that occasionally prevents it from starting. If it happens, the only way to clear it is to cut off power to it completely. I don't always want to shut off the bike to do this and so I installed a "Cut Power Button" that I can use to cut power just to the PRV. I also installed some slightly larger speakers in my lids for a little deeper bass. The schematic is the way I used a relay's Normally Closed (NC) contacts for normal PRV operations along with a momentary switch to open the relay contacts and interrupt power to the PRV.
