i had an amp that did the same thing your amp should not be doing that i dont know how old it is but mine had internal overload switch in it which kicked on if the amp was getting to hot and in my case i would say it was because of i had the amp bridged to a set of of some 100rms 4ohm speakers very nice speakers but by bridging the amp i was over loading the ohm load to the speakers and that was cause of my amp light staying the color that its was it was an old alpine amp with duo B circuitry but i hope you get your situation with this amp straited out check your contecions and if its bridege make sure the amp itself is not over heating cause that can be a problem you dont want mess with that.

Run 2 RCA cables from the two Purple connections on your Receiver (Labled "PRE OUT SUBWOOFER") to the Red and White connectors on the back of your Sub (it does not matter which Purple connecter you plug into either the Red and White)
Set the volume control on the Sub to about 75%, and keep the power switch in the "ON AUTO" position. To set the Low Pass value, look at the back of one of the front speakers in your setup, and note its frequency range (will look something like 100Hz - 17kHz). Set the Low Pass at a value slightly higher than the low value on the back of your surround speakers.
To set the phase switch, stand in the middle of the room with some music on (something with some bass, but not over the top bass) and have someone switch between 0 Deg and 180 Deg. Listen for which setting sounds "Louder and Fuller". This is the one you want. You will need to do this each time you move the Sub, as its position may change its phase in relation to the rest of your system.
