Hey Guys

I have a Sound system set up in my car and ever since I noticed my volt gauge rests at about 14-16. Usually above 14...(it rests higher after install)

My question is will a Yellow top battery help or a stronger alternator to help keep the voltage back to its original state. When I start the car the volts are almost at 16. Thanks

 

It's fine that is exactly where it should be.
