Hi. I've had my e60 with hifi $676 stereo for about a year. I just coded the denison 500s bt module succesfully, but after coding my car no longer utilizes the under seat woofers. INPA shows HIFI +> 6 SPEAKER and I am unable to activate the underseat woofers. FA in NCS EXPERT still shows the $676 option. I recoded the MASK unit back to factory using my original PSW MAN document but it did not fix my problem, just uncoded the denison. I recoded the denison and using a multimeter confirmed the amp in the back is geting power. I slaved in a new amp and connected the original speaker to it, and there is no output.



Any suggestions on how to reactivate the under floor woofers. If worse comes to worse I am just going to splice the rear speakers into new woofers and amp but that seems the mickey mouse way to go about this
