After the brief (and pretty loud) whistle, I hear a low whistling noise when driving in first gear....I dont have any problems with driving, or any loss of speed....its just the whistling noise that is really getting to me. This whistle happens every time I turn the car on, and its running at low speeds of <20mph. I live in Hawaii, if that matters - its 70-87 degs here.
When I turn the car on, it makes a whistling noise for about 2 sec What is that? on 1997 Subaru Impreza Outback

Sounds as if the AC pulley and or clutch for the condenser may be wearing out and need replaced. You need to start vechicle with the hood up and follow the noise. Need more info. to be sure but you do live in Hawaii.
