Having accepted delivery of my Formentor Beyond (same as V2) without the Sennheiser system that I had originally specced (no delivery date could be provided), I can't live with the basic sound system. If I was in UK, would be easy to upgrade at somewhere like Cambridge Audio but in Spain, not so easy. There are several competent auto electricians locally who could do this if they are provided with the equipment. So, has anyone upgraded the basic sound system on their Formentor facelift and with what equipment. I was thinking along the lines of upgrading all speakers and having an active spare wheel subwoofer such as the JBL.
