I'm looking to replace my Rainbow DL C6.2 components and Hertz HE2 amp (any offers?) for these Audison units:-

Audison VOCE AV K6 Component Speakers in the front doors. Tweeters aimed inwards.

Audison Quattro Amplifier to power the fronts and the sub.

Audison AV10 subwoofer (both fitted in the boot as I have no spare wheel to worry about).

Can anyone recommend this set-up? All comments or suggestions welcome :-)

Nice kit indeed, but what headunit would you be using ? Not the standard of course.

Those speakers are quite deep, they can be fitted but you would need extra thick baffles and the plastic grill needs to be trimmed off behind, the door cards won't fit properly still..you could cut out the factory speaker grille and replace it with acoustic cloth, with careful work you could make it look oem. Alternatively buy a spare pair of door cards to mess aroud with.
