Can you wire a car amplifier ground to a car battery?

Yes it is possible to wire your car amplifier ground to the negative terminal on a car battery. The reason why wiring a ground on a audio system to a car battery is unnecessary because you need a really long wire that goes from the rear trunk to the front hood. That is why most people who install there car amp just ground there amp to there car's bodywork using a small wire because it saves time and extra hassle. You can also but extra strain on your car's alternator. So really there is no really point of wiring your car amp to a car battery unless you have no choice!
