Its wired @2ohm to a single Alpine Type-R 12 in a sealed 3/4MDF box.  I have 4ga wire running from the battery to the amp and 4ga running from the amp to a seatbelt bolt for a ground(have tried another spot as well). I get 12.6V at the amp with the car off. The whine happens with the car in ACC or running and with and without RCAs plugged in.  If I squeeze the amp while its making that noise, the pitch changes.  Did I get a bad amp?</p></blockquote><p></p>
