Where is the best place to ground the stereo.I recently replaced the head unit unit and i can hear that constant whistling in the background.I heard it a little with the stock head unit but now it is more noticeable.

Did you keep the stock amplifiers? If so you probably have a ground loop between the output of the head unit and the amps. There is a ground loop adapter I think one of the rover parts places that will fix it. The ground inside any vehicle dash is noisy, which is fine because everything operates on DC or fairly loud AC pulses that ignore the noise. Another quick fix is get the largest DC 35V or higher cap you can find at Radioshack and put it in parallel with your power in to the head unit. Won't completely eliminate it but it will help take the edge off it. The noise could be a sign of everall bad grounding as well, so you should check your straps from the battery to the block, frame and starter. The stereo noise might be the symptom now, but eventually bad grounding will lead to poor starting and even trash your alternator and battery.

There are earthing points in the lower front, below the windscreen behind the trim (CO551)
At each lower kick panel location, behind the panels (C0018 and C0910 R/H, C0017 and C0362 L/H)
In the centre console at the rear under the cubby box (C0552, C0708 & C0362)

The wiring schematic shows C0361/1 as the earthing point for all audio header systems, but that doesn't show on the earthing point layout drawing.
