if i just run some music at listening volume with high pass filter to my stereo speakers from the amp it keeps running down to 6.2v running on an alkaline 9v battery and hasn't shut off yet i have cut the bass just to see when it will cut off and its still going

How is it able to run down to such low voltage without cutting out? does it not have low voltage protection?

its at 5.8v and still on somehow 

it finally starts cutting in and out around 5.5v
