First time poster, just saying hello and hoping to get some input on an issue after the install (I hope I'm posting this in the correct subfourm).
After playing various types of music for 30-45 minutes the amp will cut out for a few seconds and come back on. I believe the amp is protecting itself due to the fact that the amp is very hot to the touch and I can smell it also. This amp has never cut out any other time, it's only when playing it loud for a while.
The amp is alpine F450 (old AB), the 10" type S sub is bridged on channels 3 and 4 and I have Hertz HSk165's in stereo on channels 1 and 2.
Is this due to the old AB style amp? There's no fan on this amp, just heat sinks on the top. Gains are set to 60% on channels 1/2 and 75% on channels 3/4.
