Thanks Guy's, I live in Tassie so I'm hoping that Temp issues wont be too much of an issue and winter is coming fast down here!! I do like the look of this unit and the specs are great. I would like to mount it under the bonnet and have seen pic's of it mounted on the firewall on the passenger side of the engine bay. Is this area ventilated enough to keep the temp's down or do I need to place it somewhere else?
