I had this Amp in my M3 CSL but reverted it to standard when I sold it so it was removed.
I am having a 'spare room' clearout and need to get rid.
It was in full working order when removed.
Cost £140 when purchased.
See link, although price has reduced

Willing to let it go for £75ono
I would say pickup only as its quite heavy.
Thanks for looking at my advert.
