I have searched all over the place to find an answer to this and haven't had any luck. My car has a 3.5" and 6.5" in the door and I would like to run the 3.5" off of the stock head unit and the 6.5" off of an added amp. The problem is that I have to use a line out converter to feed the amp. Is it possible to wire the 3.5 off of the headunit and then off to the amp? Should this be wired in parallel or series? If the 3.5 is a 4 ohm speaker, what resistance would the head unit see?
Thanks in advance.
