Hi, I have a 2007 pathfinder with a non-bose with navigation ( see picture)
Im planning to change out speakers and add a sub to this car, and my question is how can i add amplifier(s) to the factory head unit?
Is it possible to do anythig to the factory unit, or do i need to replace everything?
I have no problem to run new wires, add amplier, sub etc, but i wonder how i can hook that up to the headunit i have now...
Anyone thats done the same with this headunit?
