guys i need your help. i have a sundown sax-1200d powering 2 sa-12s. lately the amp has been making this high pitch noise as soon as i turn my car on, and after 20 minutes of playing it will go into protect mode and it gets pretty hot. is the amp screwed up or is it something else? any help would be greatly appreciated, thanks

    are those amps strappable? if they are, make sure it's in the Master position.

    Other than that.. it's most likely a signal issue.

    Take another source like an ipod or somethin and run it's line out to the input side of the amp and see if it still whines.
