PnP upgrade to base 5 speaker stereo?
I'm planning to get our new X3 with the base (non US) 5 speaker stereo with no amplifier since the HiFi system (standard in the US) would cost nearly $2k more here.... Is there a good plug and play solution that would allow me to add an external processor (I've read great things about the JBL MS-8) without cutting any of the stock wires? If so I would like to put the JBL in the left rear compartment that would otherwise be occupied by an OEM amp and use it to power the stock speakers. I would then later upgrade the front speakers (quality coaxial with aimable tweeters?) and maybe add an external amp downstream from the JBL MS-8.
Any experience sharing or advice with upgrading the base 5 speaker system would be much appreciated!
