What do you want? Meter loud or daily loud?
Port driver's side works good for comps because you remove or tilt the seat out of the way so it's not obstructed. It reacts best with the meter on the windscreen I know from experience my Volvo was loud as FUCK when you sat on the passenger side, but on the driver's side it was quiet as hell. I see this as a bad idea for daily because the port gets blocked when you're driving with the seat in so not really good. For daily the port anywhere where it's unobstructed works well for daily, but be careful where you put it, it might meter terribly if you put it in the wrong spot.
