Audio upgrade - 2007 Autocruise Starspirit

markhp

We would like to upgrade the factory head unit in our 2007 (57 reg) Autocruise Starspirit motorhome.  We would also like to replace the door speakers.

Does anyone know what size the door speakers are in the vehicle?  Also, if anyone has upgraded, I'd be interested to hear what you upgraded to.

Many thanks!
