2010 2011 BMW 5 Series Forum F10 - View Single Post - Trying to replace broken underseat subwoofer

Hi Guys,

Also be aware that not all BMW subs have the same impedance.
e.g. the HK subs of an F10 are 8ohms, the HK subs for the F20 are only 2 ohms....

I chose to use the HK subs of the F20 in my F10. I connected these to an aftermarket amp (Match Up7 BMW). With the 2 ohms sub, the power output of the amp is much higher.

Might be good to know for later projects.. ;-)
