Question for the group. Did any of you add an aftermarket subwoofer to your fusion energi? If so, have you been able to find a way to stop the sub from turning off when the gas engine turns off? My sub only works when the gas engine is on or when the car is 100% in full EV mode with a full charge. When the car is operating as a hybrid the sub doesn't work when the car is on electric mode and only comes on when the gas engine comes on. Have you encountered a similar situation? If so, have you found a work around? I've had three shops try to trouble shoot this issue so far. I've had a separate dedicated battery installed, tried different amps, and even had a switch installed but nothing seems to work. I'd like to know if anyone was able to resolve this issue. Thank you!
