Why is my GBC continuously restarting when the volume is turned up?

So Iv got GBC, Iv fitted a Q5 OSD backlit screen, fitted a CleanPower regulator from Retrosix aswell as a CleanAmp v1.1 from Retrosix. When turning the console on with the volume low it operates fine, as soon as I turn the volume up the console restarts continuously until I either switch off the console or turn the volume down again. If I disconnect the power to the amp the console operates fine but obviously without any sound. Iv checked all wiring, nothing has shorted, Iv even redone some of the wiring and used a different amp with still no success. I suspect the amp is drawing too much power when the volume is turned up but have no idea how I would go about rectifying this issue. Any advise would be hugely appreciated.
