Default Fusion MS-RA70N head unit PROBLEM!!!

I just installed the ms-ra70n head unit on my swamp buggy. I've seen many of these installed on newer offshore boats and air boats. The install was simple enough, connected ground to ground block, hot to fuse block, remote to amps and rca's. I turn the battery's on and.... BOOM! Crisp, clear theater quality sound... so, I crank the buggy up and go for a spin. This is where the trouble is.... the second the motor cranks and my foot hits the throttle, the volume goes through the roof!!! Then If I throttle up and down, the volume goes up and down. I then tried to wire the unit direct to the battery with a online on/off switch and the volume still fluctuates with the motor on! So, what the hell is wrong with this picture??? Is it the unit or wiring???? Help me out guys! Anyone have this experience with fusion??

I suspect it is not a head unit problem but a power source issue. Where did you connect the hot power lead? Where did you ground the device? Chances are that one or the other is causing issues.
