Hello. I have a 2020 dodge ram with the factory amplified alpine system. I installed a after market boss 1100 amp and a kicker comp 10. i used the high level inputs on the amp for the signal from the factory head unit. first problem i am having is that the amp will only turn on if the car is running, and the second problem i am having is that the sub continues to play music even when the radio volume is turned to 0. any suggestions would be greatly appreciated. thanks in advance
