Problems with JL Audio fathom Subwoofer
I just purchased 2 used Fathom F113's to run in my 2 channel system. I am having a problem on one of them. When I power it down or it goes to standby the ARO settings are getting erased? Is there a battery that could be dead in it that holds the memory settings? Having to leave it on all the time to keep the setting!
