Hi I have a Jaguar XF 2014 which has the base audio, I have recently some Meridian speakers and subwoofer and a High 12 amp, I'm hoping i've done enough research before actually completing the task, my question is if I do the CCF edit to change it to High 12 and add subwoofer then install the amp will SDD download the correct software for the amp for it to work, I have SDD 167 which is online capable and have downloaded all the files for X250 to my laptop, I also have the battery backup 600w 50amp set to 14v, I have done some minor editing already (retrofit folding mirrors and puddle lights) this worked fine, any advice before I take the plunge and thanks very much for looking, Best Regards

The Amp i'm replacing is this :
