Hello all !! New to the site here and had a question that I’m sure is very simple for you all but is a great mystery to me . I have a 5 channel amp that I will be using in my truck . 4 channels to the 4 doors and the 5th channel to a sub .. what I’m wanting to do is run the 4 doors at 4ohm and the sub at 2ohm . Is this possible to mismatch the ohm load between the 4 channels and the single channel .. thanks for any and all replies ..
