At the moment I'm doing some rebuilding on my 1990 Range Rover Classic County. As for the stereo I want to build it back to the original factory spec. I know it's not the best but I want the truck as original as possible. Now my Problem: the previous ower put a aftermarket head unit in and made a real mess of the wiring. Now I have no clue how to wire the whole system back together. I have found that there is a amp missing under the cubby box. Is it the same as in the back for the subwoofer (Pioneer GM-42A)? Can anyone send me some pic. of the original system? I'm also looking to buy the headunit, cd changer in the rear and the speakers RTC7652 (front top) and one rear speaker RTC7653. Any help is much appreciated!
