If you're coming from North Ave, its to your right before you see Philam Village to your left. When you see the first Starbucks after the Caltex its the building right next to it, white building with a red and white Pioneer sign outside. If you know anyone who's into car audio ask them to go with you, they're bound to know it since it has the Pioneer service center there. When you see Mushroom Burger or Shell turn around you already missed it.
