Are speaker level outputs my only option to add an external amp to the stock sync, non-Sony system? I don't know if I want to keep this car long so don't want to do any modifications. Or rather, I want to take the equipment with me without a lot of work to get the car back to stock.
2012 Ford Fusion SE I believe.
