Alrighty, well I contacted the seller about the HU and he said I can send it in and he will exchange it. I jut hope that it doesn't take TOO long cuz this thing sounds amazing. The only reason that I thought of overheating is because this HU runs 70x4 watts...which is higher than most other HUs. I don't know too much about car audio components, which is why I came here to ask you guys. Thanks for the input.
