2003 import stereo.... etc
 

I'm certain this has been done to death but will ask anyway. Can a new stereo be fitted to an import without cutting the panel, or has anybody got a uk panel I can use? Also I want to replace the back box with a standard or standard looking one as the current oversized one scares the neighbours. Any suggestions as to where to source parts in the London/ Essex area? Any help would be appreciated, thank you in advance.
