I don't dry camp, so I went ahead and connected both wires to the battery wire. I thought about opening a gap, but the wall has a void that extends the entire length of the wall, so it should get enough ventilation. I really like the Jensen. There was an immediate improvement in sound quality and install was pretty easy.
