Are the subs connected to your amplifier as it does this??Remove the sub wire from the amplifier and see if it continues. Turn system off then back on without the subs wiring connected to see if it continues.

Yes, one W7 is connected to the amp. It's easier for me to disconnect wire at the sub end. Will that serve the same purpose? Thanks for the quick response.

What Sub woofer or subs do you have hooked up to it?? What Final OHM load are you at with the sub/subs? If it is the amplifier Im thinking that it is.. It is only rated from 4-1.5 OHMs only and will have issues at a 1 OHM final load

Is your W7 a 3 ohm Sub?

!st // we are seeing if there is actually an issue with the amplifier without a load on it other than just power/supply. if it does the same.. Then possibility issue with a ground or loose supply connection. If It Lights up Green and seems fine without the Sub wired up. the amp should be ok.. turn back off wire sub back up.. If It goes back to amber/ect.. Its possible that the Sub would be the Culprit/Issue, possible bad coil, or even Loose connection within the enclosure.This would be the Time to Pull the sub and remove from the enclosure, and wiring from the amplifier and check the Coil/coils with a Digital Multimeter(Walmart has one or Orileys for like $30 bucks)@ Ohms value

Im Kind of leaning towards a Bad sub at the moment
