Hey guys I have a 2017 Hyundai Elantra and there is next to no info online about how to install a high output alternator or any companies that make them. I want to get a 3k amp and my stock alternator is simply not enough. I have heard by many that it is not possible due to the computer controlling the charging system. Plus on the negative battery terminal post there is what appears to be a sensor of some type. Does anyone here have videos or pictures of one being done? Surely I can’t be the only person with a 2017 elantra that wants to have a loud sound system.
