I like how stock and how much utility you get from this mod?
1. Are you able to charge and use AUX input at the same time?
2. Where did you get the parts; I haven't been able to pull the part numbers from Crownauto, Pelican or Tischer.
3. Is there anyway to improve or avoid power spikes when turning the car on of off?
4. How much in parts did it cost you?
