I am new to the group and am asking a question regarding the fitting of a
Kenwood subwoofer to my 2000 model Range Rover. I assumed the fitter would
use the line out from the factory fitted (Alpine) unit but he used the "rear
speaker feed". He insists the speaker feed is just as good. Is there any
difference between using the line out or a speaker signal? Please would
someone explain the difference?

Many thanks,

David
