mahapederdon Posted December 16, 2017 Share Posted December 16, 2017 I just installed a 2400 watt amp and a 1200 watt 6 channel amp in my 2011 fusion SE. I read somewhere that some of these newer ford cars have a (smart charging) where the car will sense load and demand more or less from the alternator depending on what it says it needs. And using aftermarket amps connected directly to the battery will adversely affect charging. How do I know if my car has this. I don't see any shunts or anything on my visible power wires to from battery/alternator. I'm worried if I turn my stereo up I might hurt something on this car. Thanks in advance on any input or help any of you throw my way. 0 Quote Link to comment Share on other sites More sharing options...
