I am trying to add an amp/sub to my completely factory system. The amp I am using has high and low level inputs. I would prefer if I could run low level inputs, and since the signal from the headunit to the amp should be low level, it seems like a valid possibility. What I am thinking of doing is tapping into the LR+/- (from the head unit to the amp) wires, and running parallel to a soldered rca plug which should be able to plug right into the amps low level inputs. Also, while I am asking, if I do have to resort to running high level inputs, do I have to "use up" one of my rear channels or will I run into difficulties if I run it parallel? I measured the amp resistance at about 12 ohms, so using ohms law the channel would be about 3.5 ohms which might be too low for the factory amp.
Anyone have any experience with this?
