Hello, new here 1st post!
I'm trying to figure out the speaker/ subwoofer ohms (2/4?) of the 2015 focus titanium stereo system. I'm considering replacing just the speakers and subwoofer but don't really want to change anything else so I want to make sure I'm matching whats already being powered by the 8" system. TIA!

 

This can involve knowing the output of the matching transformer for the speakers. Usually the transformer is matched with the required output of the speakers.
