Another way is to wire the radio directly to the battery (via an in-line fuse) using heavy duty cable. This keeps the choke in series with the +ve lead but also uses the capacitance of the battery to smooth any spikes even further. Maplin Electronics stock such things as gold-plated battery terminals and connectors, oxygen-free power cables etc ... Overkill? Moi?
On a related note, it also helps to install sound-deadening foam in the door cavities and under the bonnet lid. At higher volumes this does help to stop the bodywork rattling <img src=icon_smile.gif border=0 align=middle>
Best of luck,
Steve.
