My HFi is still cool to the touch after playing. The only time I've managed to even get it warm (not even hot) was after an hour long trip with my friends with everything full tilt most of the way.
I also just mounted it vertically with space underneath it for ventilation, which should cool it off even more
Like I said I had no problems with the HF 1500 but the BRZ was an even trade bc he was selling whole system I agree the Hifonics HF at that price range is unbeatable. I think I paid $160 for my HF1500 new
